With the explosion of Internet digital entertainment, online music has become the main way to enjoy music. Wireless speakers are good partners for online music, allowing us to enjoy music at will. At present, wireless speakers are mainly divided into Bluetooth speakers and WIFI speakers. Bluetooth speakers have the advantages of simple connection and good compatibility, while WIFI speakers provide better sound quality. Today's Longines M600 is introduced by Love to play computer games A portable Bluetooth speaker for trial use.

Product introduction/unpacking

Founded in Shenzhen in 2009, Longines Audio is a national high-tech enterprise focusing on digital audio development. Longines M600 is the latest multi-functional portable Bluetooth speaker released by Longines Audio in 2016, which supports multiple playback modes such as Bluetooth 4.0 wireless connection, card playing, and AUX external audio source; There are also functions such as Bluetooth hands-free call, real-time voice broadcast, one button folder switching, memory card reading and writing. The 8800mAh battery provides an extremely long playback time, and can also serve as a mobile power supply to provide 5V-2A output current.

Longines M600 is packed in cartons, which are traditional in both form and design. The corners were slightly deformed when the package was received, which didn't give a good impression.

There is a thick buffer layer in the packaging box to wrap the speaker, effectively avoiding damage during transportation. In addition to speakers, there are instructions, membership cards, AUX cable, charging cable and other accessories.

Summary

The packaging texture of Longines M600 is not good, and the carton hardness is not enough, so it is easy to be squeezed and deformed during transportation. Since charging requires 5V-2A current, it is better to configure a power adapter as standard.

Appearance/details

The Longines M600 is rectangular in shape, with two colors: Charming Black and Elegant Grey. Charming black is black matte paint, elegant gray is gray metal paint. This trial is Charm Black. The volume of 250mm * 147mm * 69mm is a big block in portable speakers, and the weight also reaches 1354g. The speaker is surrounded by a ring of hard plastic, and the front is made of anti splash nylon fiber silk, which can prevent daily water splashing and reduce accidental damage.

One of the highlights of Longines M600 is the leather portable design. The leather is soft, and Longines logo is embossed. The thread and rivet process are simple and elegant. With the portable design, it is very convenient for both indoor mobile speakers and carrying out.

The top of the speaker is the main control board, covered with soft rubber, with control keys MIC、 Bluetooth indicator, power indicator. The key area is large and the touch is 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 TF card songs, 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 back of the speaker is made of hard plastic, which is designed symmetrically. The left and right hollow openings are the bass passive units, and the lower nameplate is marked with the machine model, input current, company name and other information.

Careful friends may have noticed that there is no power switch button in the control button introduction. The secret is hidden under the rubber plug on the back. Open the rubber plug downward to see the TF card slot, power toggle switch, AUX input, Mirco USB charging port and USB power output port.

There is a wide black rubber anti slip strip at the bottom of the speaker, which is used to shock absorption and increase friction, reduce resonance with the placement platform and speaker displacement caused by bass. Like the top rubber, the anti slip strip is easy to get dirty and needs to be wiped with a wet cloth to clean it.

Summary

The Longines M600 gives the impression that it is powerful, and the body workmanship is satisfactory, with tight joints and no burrs at the opening. However, there are also some problems, as follows:

1. Although it has a portable design, its large size and 1354g weight make it a little inconvenient to carry it outside.

2. The power switch is set under the rubber plug on the back. It is not very convenient to turn on the power switch every time.

3. The interface is designed above the fuselage. Although it is more convenient to operate, it makes the fuselage easier to be knocked over when charging, AUX external audio source, etc.

4. The rubber at the top key is easy to stick and not easy to clean. There is no backlight, the touch of key icons is not easy to distinguish, and blind operation is not allowed in dark environment.

user's experience

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 device 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. Personally, I think it is more beautiful to use one indicator light with different colors to display the power.

The Bluetooth version of the speaker is 4.0. The official transmission distance is 30 meters. The actual signal is stable without automatic disconnection. When answering the phone, the MIC can pick up clearly at a distance of 1 meter. To charge the device, you need to press the battery key briefly in the shutdown state to set it to the power output mode. It is more practical if you can charge the device while playing music.

TF card music playback, supporting MP3, WMA, WAV, APE, FLAC full format decoding.

Longines M600 sound generating unit consists of one 3-inch woofer, two 2-inch full frequency speakers and two 90 × 60mm bass passive units. 2 × 20 Watts Texas Instruments 5 series chip, 17 Watts rated power, is a "luxury" configuration on portable speakers.

At the beginning of listening, the sound of Longines M600 was relatively stuffy and tight. After several days of playing, although it has improved, the sound still can not come out. The seamless design of the front panel not only blocks the entry of splashing water, but also affects the transmission of sound. Three songs of different styles were selected for this listening test, namely Vitas Onepa 2, Song Dongye Anhe Bridge and Xiao Jingteng Princess.

Vitas' treble is not the highest in the world, but it is definitely unforgettable. When playing Onepa 2, Longines M600 was quite ordinary and behaved in a normal way. Because only full frequency units are used without independent tweeter units, this performance is also expected.

In "Anhe Bridge", the drum echo did not delay, and Song Dongye's low male voice performance was quite up to standard.

Xiao Jingteng's "Princess" is a popular rock song, which uses more electronic sounds. Due to the use of independent bass unit+dual passive unit, the atmosphere of the whole song is rendered in place, the voice is clear, and the bass can be freely played, which makes the performance satisfactory. The disadvantage is that the resolution is not enough, and the background instrumental music is difficult to distinguish, which is also a common problem of Bluetooth portable speakers.

Summary

The Longines M600 has only been recharged once during its use, and its endurance is satisfactory. There is no annoying background noise when Bluetooth is connected, which 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.

Although the official claims that Longines M600 is a 2.1 channel loudspeaker system, it does not actually use a frequency division design, but only adds an extra bass unit compared with the general portable speakers. The bass does not give people an amazing feeling. The advantage is that the response is fast without procrastination. The disadvantage is that the bass volume is not too much and the diving is not enough. Thanks to the 17 watt high rated power provided by TI's 5 series chip, the speaker will not break or distort at the maximum volume. Everyday listening to music, the high voice performance is average, and the low frequency is basically satisfactory; When used to watch movies, dialogue and background music are better separated, but the effect is not as good as the real 2.1 integrated speaker. Overall, the sound quality of Longines M600 is not very impressive.

Outdoor Scene Painting

Longines M600 can be placed horizontally or vertically; It can be hung and reclined at will. Let's enjoy its enchanting posture outdoors.

Experience summary

I prefer wireless speakers, and I know a lot about wireless speakers. Used wireless speakers include Libratone Zipp, Harman Carton onyx studio, Sony X77 MIFA M9、Auluxe X6、 Le Pao Magic Elephant, among which the volume of Sony X77 is Longines M600 The price of Auluxe X6 is the closest.

The volume of speakers is opposite to the sound quality. In the same situation, the speakers are bigger and stronger. Sound boxes also apply to the principle of "one penny for one thing".

Only by clarifying your own needs, determining the purchase price and reasonable expectations can you choose a wireless speaker that you are satisfied with. Finally, summarize the writer's personal opinion.
