There are many audio contacts like this and that, but they can't compete with the sound of the car flute. Especially recently, the national road that Xiaoyou rode suddenly saw a surge of trucks. The roaring engine sound, the flying dust of the big car wind, and the sharp whistle sound make many of my friends' voices look like duckweeds on the sea. They are constantly submerged by the sea water, and constantly rise out of the sea. Let's not mention the anxiety of listening to songs.

With the appearance of Longines M600, children finally have a sharp tool to listen to music without fear of car speakers.

1、 Large and portable

One of the highlights of Longines M600 is that it is designed with a hand strap, and this design has been extended to the outer packing box. ha-ha! It doesn't look like an expensive gift box.

Product list: 1 Longines M600, 1 Micro USB charging cable, 1 3.5mm audio cable, 1 user manual.

The front of the fuselage is made of waterproof, dust-proof and abrasion resistant fabric, which is very practical and beautiful with texture, feel and visual impact.

The back is designed with a mesh cover. Although it is made of plastic, it is very metallic. wait! There is a good comparison here couplets.

Upper link, bass passive unit; Lower link, bass passive unit. The match is neat.

Horizontal batch, silicone cover. Inside the cover, there are holes: TF card socket, power switch key, AUX socket, Mirco USB interface, USB power (data) interface from left to right.

Maybe it is to consider the need of outdoor waterproof, but I still disagree with you. I can't help but complain for the first time: as a necessary key, the key switch can't be crossed and simplified every time I use it. It's set inside the cover. In this way, every time the machine is turned on and off, three steps are needed - first, then the cover is opened, shut down, and then the cover is closed. It is recommended that the power switch key and the mobile power wake-up key be built together on the top.

At the top are function keys: pause/play, short press: switch to the previous song/long press: volume decrease, short press: switch to the next song/long press: volume increase, folder switch, mobile power wake-up, Bluetooth phone answering, mode switch, a total of 7. The abundance of keys indicates the power of functions.

In addition, there is a row of holes: Maikong, Bluetooth, and power indicator.

Friendly prompt is also the place where I was confused: volume adjustment and up and down music switching share the same key position, but the length of the manipulation is different.

One thing was said, Xiaoyou complained for the second time: the default volume after the initial startup or mode switch was too high, and Xiaoyou's fragile one should be careful not to get dirty!

The bottom of the audio is a non slip mat of the same size (i.e. symmetrically distributed) as the top button, which has excellent anti slip effect.

The surrounding frame of the audio is made of plastic oil spray technology, which is round and solid, and seems to be inlaid with a ring of bright metal edges.

Longqin M600, I won't get used to you just because I love you. For the third time, I complained that because of the plastic material, it is easy to scratch around and leave scars.

The reason why Longines M600 audio dare to claim "portability" is that this soft leather hand strap, Longines LOGO, metal rivets, and fine stitches, no matter in material, process, or design, no matter where they are, no longer show the majestic spirit of the king.

The Longines M600 sound system is designed in a standard strip shape, which looks like a silly brick shape, but because it is covered with mesh fabric and leather handles, it looks simple and unusual, clumsy and grand.

2、 Multi functional, different

The real strength and high-end of Longines M600 audio is its outstanding functions. With regard to these functions, we can roughly perceive them through their outer packaging.

The back of the outer packaging box and the left and right sides are either outlined or detailed, or text or graphics, bombarding users with many functions of the Longines M600 audio: Bluetooth wireless, voice broadcast, hands-free call, mobile power, card insertion play, external speakers, folder switching, card reader, and splash proof. Each function is so shiny and dazzling, fully meeting the different needs of different users.

As a sound, no matter how complicated its auxiliary functions are, we cannot give up the requirements and pursuit of sound quality.

After connecting Longines M600 and playing games on the tablet, the shock is called immersive.

Recently, there are too many vehicles riding on the road. For safety reasons, the outdoor sound effect experience of Longines M600 moves to the sea and sky where the sea breeze is roaring and the sea waves are surging. The sound effect in the card reading music mode seems to contend with the tsunami, and the outstanding king style of Longines M600 can be seen naturally.

The external sound source mode is also competing with the sun and the moon, which shows the dominance of Longines M600.

After the outdoor Bluetooth wireless connection to the Longines M600, the sound effect is the same as that of the external audio source mode, which can clearly sense the crispness of the midrange.

People are on the journey. There are too many beautiful sceneries. My mobile phone has no power. The Longines M600 can be used as a mobile power source to charge mobile phones. It's really a creative function and play! In the future, if you travel outdoors, where will your mobile phone be without power?

Friendly Tip: When charging your mobile phone, remember to press the mobile power wake-up button on the top!

Folder cut songs, dad's storytelling, opera, wife's pop music, son's reading nursery rhymes... haha! Clear and orderly, no matter how complicated the listening needs are, they will not be in a hurry. They can be easily handled with one click!

It can also realize the function of card reader. After connecting with the computer through USB power cable, you can directly operate the files in the TF card, which adds the ability of convenient experience.

3、 Strong sound effect, professional quality

In terms of channel system selection, Longines M600 uses 2.1 channels. That is, one 3-inch 10W woofer in the front and two 2-inch 3.5W full frequency speakers in the rear, and two 90X60mm bass passive units in the rear, making the treble crisp, the midrange mellow, and the bass deep.

In the actual playing effect, Longines M600 has a magnificent sound range and a strong bass. When they are in the square, the sound effect is no less than the outdoor speakers of the square dance ladies.

Longines M600 adopts TI's new 5-series class D chip, which contains DSP digital sound effect operation and supports full format decoding of MP3, WMA, WAV, APE, FLAC, etc.

In addition, the 20HZ-20kHZ frequency response range of Kuang Longqin M600 enables children to clearly feel the vibration and tremor from music playing when holding it in a single hand, which is a kind of enjoyment of pounding the body and hitting the soul, no less than the thrill of disco.

For speakers (especially outdoor portable speakers), there is also an important performance parameter that needs to be focused on - signal-to-noise ratio. Signal to noise ratio refers to the ratio of the normal sound signal played back by the speaker to the noise signal (power) without signal, expressed in dB. The higher the signal to noise ratio, the lower the noise. Therefore, for speakers, the higher the value, the better. Because when the signal to noise ratio is low, the noise is serious when small signal is input, and the sound of the whole range is obviously turbid, so it is not recommended to buy the one with the signal to noise ratio lower than 80dB. My little friend's heart immediately became uneasy. I had fallen in love with Longines M600, but whether he would capsize in the gutter made my little friend's heart feel sick and confused. A closer look shows that its signal-to-noise ratio is up to 97dB. You should be careful! I finally fell to the ground.

Longines M600 adopts 17W rated output power, with strong penetration and no fear of obstacles. It can achieve the best sound quality both indoors and outdoors.

Other parameters, such as size: 250x147x69mm and weight: 1354g, show that the size and weight of Longines M600 should not be underestimated, and the battery capacity of 8800mAh shows that its super long standby and mobile charging function is not a false name.

The Longines M600 mainly focuses on the Bluetooth function, but the Bluetooth version is slightly lower, which is not as powerful as 4.2.

4、 It's so comfortable, enjoying a leisurely journey

Longines M600 is suitable for home and outdoors.

The piano complements each other.

Before the computer, Ben is the same root.

In front of the window, help and stare.

Next to the TV, add another scene.

On the tea table, accompany the sofa.

A tent is set up by the sea, and the harp is playing.

Looking for historical sites, Longqin breaks the time and space.

In a word, as long as the sound of Longines M600 is heard, you can enjoy yourself forever.
