With the rapid development of technology and economy, people who yearn for leisure after a fast pace have incorporated portability into their lives. Portable audio, which can provide people with high-quality music anytime and anywhere, quickly integrates into modern life and becomes an indispensable part of modern life; The original intention of portable audio design is to better let the majority of music listeners enjoy this simple, convenient, anytime, anywhere music festival. With the support of high-tech, portable audio products have gradually become more functional, and the sound quality is better than before. Because "portable" is loved by people, portable audio can be found in many leisure places. With the improvement of living standards, the demand for portable audio is increasing, and the demand for portable audio is also increasing. I am here Love to play computer games Fortunately, I applied for the chance to try Longines M600. Now let's take a look at how the portable audio system with one 76mm woofer, two full frequency speakers, two passive bass units, 2.1 channel loudspeaker system, 8800 large capacity battery, Bluetooth 4.0 and card plug and play function performs? Can it stand out from many portable audio systems and win the favor of many users?

Unpacking impression

After receiving the express bag of Longqin M600 from the courier, I felt a little heavy at first. Longines M600 are portable The outer package of the paper box is printed with the physical picture of Longines M600 on the front. The shape of the square brick is stable and low-key. Good music comes from good products. After listening to it, we know that it has connotation, simple appearance, powerful functions, graceful music, and leisurely expression. After listening to it, friends who come to visit home praise it repeatedly, which means it is called the "magic cube" of music!

The hardness of Longines M600 packaging carton is obviously not enough. In addition, the express delivery is a bit violent. When the express delivery brother handed it to me, the outer packaging box had been slightly deformed. When I opened it, I felt it was unnecessary to worry, because the whole packaging protection of Longines M600 was in place.

On the back of the packing box are the eight main functions of the Longines M600, and the lower part has the official QR code, as well as the accessories and performance parameters contained.

The packaging and protection of Longines M600 audio are good. The audio and accessories are all packed in thick plastic foam foam shock absorption boxes, which can effectively avoid collision damage to the product during transportation.

In addition to the fact that the whole stereo is wrapped by a plastic foam sponge with high elasticity, even the handle is stuffed with a semicircular fixed plastic foam sponge. The gap between the plastic foam sponge and the packaging box is identical, and it feels useless when taken out.

Here is the family photo of Longines M600: Longines M600 audio host, audio cable, data cable, instructions and a two-dimensional code card of Longines.

The data line adopts the flat line design, which is convenient for line management and is not prone to winding. It can be seen from the measurement that there is more than one meter, which is very convenient to use.

The audio cable adopts a soft cable with a non slip texture, which is soft and elastic, and is not easy to get entangled. It can also be seen from the measurement that the material is thick and convenient.

On the upper left corner of the outer packing box, there is a special label for trial use, indicating that This product is provided for trial use by Aigoji. Netizens who are familiar with Lei Feng's website know that the predecessor of computer trial is Lei Feng's trial. It's the first time to see the icon of computer trial!

See the words "splash proof" on the upper right corner of the outer packing box? We have seen splashes on the packaging box in many fruit advertisements. This is not designed to look good. The Longines M600 supports splash proof water. Of course, we do not understand that it has the waterproof function of throwing into the water like a waterproof mobile phone. This is to deal with some accidents in daily life: for example, accidentally knocked over a drink bottle during a dinner party, It is just splashed on the sound, and the splash proof function can greatly reduce the probability of damage to the sound caused by some accidents.

From the features marked on the package, Longines M600 supports eight major functions: wireless Bluetooth, voice broadcast, hands-free answering, mobile power, TF card plug and play, AUX input, card reader function, etc.

According to the performance parameters, Longines M600 supports the standard 3.5mm input interface; The weight of the product is 1354g, and it is still very important to weigh it by hand when opening the box for the first time; The built-in 8800mAh battery can be used as mobile power to charge other devices. This capacity can basically charge ordinary mobile phones twice or three times; Card insertion It supports a maximum capacity of 32GB, which is sufficient for copying and playing audio data; In addition to charging, the data cable interface can be used as a card reader to read and write TF cards inserted in the audio.

Appearance details

Longines M600 audio has two colors: Charm Black and Elegant Grey, with matte paint and metal paint respectively. The front mesh panel is made of new waterproof nylon fiber silk, and the back is designed with organic plastic mesh. The products are well made, and their excellent appearance and workmanship are not inferior to those of international brands. The test machine applied for this time is elegant gray. The main control panel is on the top of the audio system. There are seven main control buttons, MIC, Bluetooth indicator, power indicator, etc.

There is a ring of hard plastic material around the audio, and the front is made of anti splash nylon fiber silk weaving material, which can prevent daily water splash and reduce accidental damage.

The frame and back of Longines M600 are not made of metal, but of baking plastic. The metal paint surface feels smooth and the painting process is of high standard. Symmetrical design is adopted on the back, and the left and right hollow openings are bass passive units, Two large woofer windows bring a shocking bass effect to the M600. The nameplate below shows the machine model, input current, company name and other information. With a volume of 250mm * 147mm * 69mm and a weight of 1354g, Longines M600 is a big player in portable audio.

There is a wide black rubber anti slip strip at the bottom of the speaker. On the one hand, it can stabilize the effect of the speaker and reduce the wear caused by the direct contact with the desktop. On the other hand, it can also reduce the resonance with the contact surface when the volume is high to a certain extent, increase the friction, and avoid the displacement of the speaker caused by the resonance caused by playing music. The anti slip strip is not resistant to dirt and needs to be wiped with a wet cloth to clean it.

With the portable design of hand strap, the Longines M600 portable audio really deserves its name. The dark brown soft leather hand strap, Longines LOGO, metal rivets, and fine stitching make this Longines M600 more fashionable. The Longines M600 is a little heavy, and it is not afraid of falling down when you have a hand strap. It is very convenient both for indoor mobile audio and for carrying out.

Functional experience

Main control panel on the top of the audio Compared with most Bluetooth speakers, it has several more keys, and the rich keys show its powerful functions. Follow the instructions to be familiar with and easy to understand. The main control board has a large area. Although it is covered with a silicone layer, it feels good. The M key is used to switch between Bluetooth AUX 、 There are three sound source modes for card reading. The Bluetooth/Phone key is used to disconnect the current Bluetooth device from the new device; Answer the call when calling; In the answer state, it is to switch back to the phone call. Short press the battery key to display the power. When playing the songs in TF card, the folder switch button is used to switch the tracks under different directories in the card, which is convenient for users who like to classify. Long press one song/previous song to adjust the volume. The key panel is covered with integrated silica gel to wrap the keys, which can be waterproof in addition to good hand feel. The only disadvantage is that the keys are not easy to identify in a dark environment.

The following is a screenshot of the schematic diagram of the product manual. We often see some function keys, and we all know their functions. There are other function keys that are not available in the audio system: the switch folder key (for music in multiple folders, you can press the key to switch folders. This function makes it convenient to select and listen to classified songs according to your needs or mood. For example, if you dance square dance, you can choose to play the music in the square dance folder; if you practice yoga, you can choose to play the music in the yoga folder; The parents' opera storytelling, the wife's pop music, the children's reading nursery rhymes... each set up a separate folder to play in an orderly manner, and it is easy to select one button to do it. If they are all copied to the root directory, it will not be so convenient to select them!) The mobile power wake-up key (short press to set the power output mode when the machine is turned off to charge the mobile device) and the mode switch key (wired mode, Bluetooth mode, card insertion mode) have voice prompts for different mode switching operations, which are good prompts for elderly use and blind operation. It is easy for everyone to operate according to the instructions, and it should not be difficult for elderly children.

The following is a screenshot of the interface diagram on the back of the product manual. It should be noted that the Micro SD card slot has the function of a card reader. Just use the USB data cable to connect the computer and the speaker. After the audio is turned off, you can directly read and write the TF card content of the speaker by operating the computer, which saves the trouble of plugging in and out and is convenient to use. For the mobile power output socket, this function is turned off when the power is on, Power output is available only when the machine is turned off. Take the Longines M600 with you when you travel. You don't need to worry about the power loss of your mobile phone any more, so you can have fun and be more comfortable.

According to the official data of Longines M600, the configuration and audio unit materials of this Bluetooth audio system are quite sophisticated.

The front three active units (one 76mm low-frequency radiation basin+two full frequency units) form a 2.1 channel structure, and the rear two 90mm60 bass passive units can provide a shocking bass effect; Built in four 2200 mA batteries form 8800 mA capacity, rated power: 3.5 * 2+10W, rated impedance: 6 ohms (bass), 4 ohms (high pitch).

Longines M600 is defined as a portable audio system. It is considered as a "luxury" to use such a configuration on portable audio systems, and it is no exaggeration to use luxury to describe it.

Although the Longines M600 can play songs in many ways, the most common one is Bluetooth connection. After the power is turned on for the first time, the blue Bluetooth indicator lights up, the speaker defaults to Bluetooth mode, and there will be voice prompts. Find the M600 on the playback device with Bluetooth, and click to connect. Longines M600 will remember the last use mode. For those who like to insert TF cards to play music, it is not necessary to switch the mode every time they start up. Gently press the battery key to light up different numbers of red indicators to indicate the current power.

Answer the phone at a distance of 1 meter from Longines M600, MIC can clearly pick up sound.

To charge the device, you need to press the battery key briefly in the shutdown state to set it to the power output mode.

The Bluetooth version of the speaker is 4.0, and the transmission distance officially marked can be up to 30 meters. The actual signal is stable, without automatic disconnection or annoying bottom noise. This is commendable. There is a voice prompt when switching between different functions. The size of the prompt tone is synchronized with the speaker volume. The prompt sound is very abrupt and disturbing when the volume is high. I hope the official can update the firmware to set the volume lower, or can choose to turn it off. TF card music playback, supporting MP3, WMA, WAV, APE, FLAC full format decoding.

With the AUX external audio input interface, it is convenient for those playback devices without Bluetooth to access, and can also output higher quality audio sources.

Sound quality test

For a sound system, no matter how many functions it has, the final view is the sound quality. Since I received the Longines M600, I searched the bottom of the box to find out how to cook music when I was free. Although it was not a high-end speaker, it was still good to cook. After several days of cooking, the results were obvious. Of course, it's better to try out in the dead of night. Find out the test disc. To avoid affecting family members, choose the day of duty. Take everything with you, pack your bags and go to the duty room of the unit to begin the audition experience of Longines M600. A few familiar tracks selected for testing relatively high quality speaker equipment have been overused, but the more familiar the songs are, the more you can compare the trial products and distinguish the performance of the products?

Track 1 "Ferry": Cai Qin's "Ferry" is a required track for testing at ordinary times, because it can intuitively hear the expressiveness of tri band. Listen to the Longines M600. The first drum sound gives you a very good sense of immersion. The drum sound is amazing, and the banging sound is not muddy. In the dead of night, listen to the voice of Cai Qin, the queen of folk songs, with Longqin M600. The treble is sonorous, powerful, clear and not harsh; in The frequency is prominent, round, natural and textured, and the vocal processing is quite mellow; It can restore the guitar, bass and drumming; The articulation of middle and low tones is also clear, but the convergence of residual sounds is not enough. Of course, it has no comparability with high-end speakers.

Track 2 Hotel California: The classic song of the Eagle Band. Without hearing the song of the Eagle Band, you can't understand what real rock music is. This fast and cynical song is very strange in melody. The skillful guitar skills and hoarse voice interweave a luxurious and casual music magic space, which is a big test for the portable sound of Longqin M600. On the whole, Longines M600 performs fairly well, and its sound field, musical instruments and content are also rich. Although the sound lines of the guitar are not exquisite, they are OK. In the frequent bass impact, they can be analyzed, which is amazing for this portable sound. The low-frequency elasticity is also available. The vicissitudes of the male voice are well explained, but the bass still has obvious buzz.

Track 3: Pipa vs Saxophone: This special piece reflects the blending and collision of Chinese and Western cultures, focusing on listening to the Longqin M600 to analyze the performance of the pipa in high frequency, and can be compared with the low-frequency saxophone. Listening to the Longqin M600 to analyze the sweet and sharp treble in the quiet night, you can also feel the sound overlapping between the left and right ears.

Track 4: Qinghai Tibet Plateau: This is not a song you usually listen to. This is the test song in Anqiao Test Disc II, a song performed by various musical instruments. After listening to the analysis of Longines M600, the drum sounds elastic at the beginning, but the diving is not enough. The next gong sounded, probably because I turned on the viper sound effect. The sound rendering is pretty good. Xun's voice is thick and deep, but it is a bit humming. The flute sound is melodious and crisp, and the high frequency is extended, but the sound field is not wide enough. The last few drumming sounds are elastic and slightly inadequate. When the viper sound effect is turned off, the effect is much worse.

Track 5: White Haired Girl: This is also the test song in Anqiao Test Disc II. Although it is 2.1 channels, Longqin M600 does not accurately locate the sound production. High frequency has fair performance, almost burr feeling, and the sound quality is general; Low frequency is relatively inferior, lacking quantity, and the dive is not deep enough. The overall analytical performance is more than that of many ordinary portable acoustics. The sound of various musical instruments, especially the flute and erhu, has retained some sound details, but is not rich enough.

In general, the sound of Longines M600 multi-function wireless Bluetooth portable audio is natural and pure, and the subwoofer effect is excellent. Even if the volume is adjusted to the maximum, there is no broken sound. The low frequency is short of quantity, the dive is not deep enough, and the performance of residual convergence is not enough. After all, it is a hundred yuan product, which has no comparability with high-end speakers.

Take photos of life

After writing so much, play a piece of pure music "Mystery Garden" with Longqin M600 to have a rest and take some photos to see what my life has changed since I owned Longqin M600.

On the weekend, about three or five fishing friends took fishing gear to the river to fish, set up fishing gear, and played some light music. Be careful not to play too loud! Don't scare away the fish.

When you go camping, don't forget to bring the Longines M600, which can create an atmosphere of infinite joy for outdoor life. In addition, it has the reverse charging function, which can charge mobile devices such as mobile phones and tablets. The 8800 mA battery is enough to charge the phone 2-3 times. With this function, you don't take or forget to take the mobile power when you go out, and you don't have to worry about what to do when the phone is out of power.

Longines M600 is mellow, delicious and spiritual food, which can make your life full of emotion! Have a picnic with friends, drink some wine, and have some background music. It's just fun to be cheerful, and push the cup and change the wine to be sincere!

Three or five friends, a pot of tea, Steal a half day's leisure, quiet and indifferent, taste life, put a piece of heartfelt fragrance in the jade pot, play a zither song "Spring River Flower Moonlight Night", watch Maojian dancing in the teapot, take a mouthful in your mouth, let all taste buds feel the natural fragrance and pure sweetness, and have a faint smile in the center of music's comfort to the soul.

Sitting by the floating window on the weekend, listening to music and reading books, I seem to find some sustenance. My heart is as flat as a bend in the lake in the deep mountains and forests, with no one to step in, no wind to stir, no ripple; Occasionally, the inextricable complex, the inextricable result, and the unattainable desire are slowly relieved.

Whenever you drag your tired body home, take a comfortable bath with warm water in the pool, play the last song "Fishing Boat Singing Evening" or "High Mountains and Flowing Water" with Longqin M600, listen to music while taking a bath, relax your body and mind, and have no fatigue. Longines M600 is splash proof and can answer the phone with one button!

Longines M600 is equipped with a handle. Its portability is very good for middle-aged and elderly people who like walking and morning exercises. It is absolutely a good choice as a gift for the elderly.

Summarize recommendations

After this period of trial, the Longines M600 has left a deep impression on me. Both the workmanship and the functions are relatively good. The stable appearance is low-key and has connotation. Wireless Bluetooth, voice broadcasting, hands-free answering, mobile power supply TF card plug and play, AUX input, card reader function, splash proof, reverse charging of large capacity power supply and other features are powerful as portable audio functions; In terms of sound quality and sound effect, the high frequency is abundant and powerful, the mid frequency rebounds moderately, and the low frequency diving also exceeds the ordinary portable sound. The sound color is natural and pure, and the high, medium and low frequency performances are relatively excellent. For products worth several hundred yuan, they have no comparability with high-end speakers, while the price in the same price sound has a strong cost performance ratio and good competitiveness. We don't expect to buy 1000 yuan sound quality at the price of 100 yuan, but at the same price, the Longines M600 is definitely worth the price. In the trial, only to do better, Suggestion:

1. The keys are not easy to identify in a dark environment. If you are worried about the cost and do not consider adding electronic light displays, you can consider using luminous paint.                                        

2. It is a great pity that there is no radio function. It is recommended to add optional models with FM radio.                                                             

3. It is recommended to increase the voice prompt volume setting for the abrupt and disturbing voice when playing music on the mobile phone.
