They seldom listen to portable speakers, mainly in terms of sound quality. Their performance is too poor. Unless they are foreign brands, domestic portable speakers are usually inseparable from the label of "cheap". However, portable speakers can be separated from computers, and the advantages of independent use have been favored by many people. Moreover, with the tireless improvement of Chinese people, most of these speakers also have lithium batteries FM radio, built-in memory card and other functions. I was lucky to experience the Longines M600 wireless Bluetooth speaker, which gave me a new understanding of domestic portable speakers.

1、 Appearance appreciation

Usually, I don't pay too much attention to portable speakers, so I don't know much about Longqin. Later, I learned from the data that Longqin is an enterprise focusing on the development of small volume speakers and portable speakers. It is also a relatively qualified enterprise, and has a pursuit of product quality and functions.

Accessories of Longines M600 speaker: speaker, charging cable, AUX cable and instructions.

The sound box has a distinctive shape design, similar to B&O A2 A rectangular shape with a bracelet. Maybe it's because of the built-in battery. It's still heavy to carry, just like a brick.

The bracelet is made of leather and connected by rivets. It is retro and textured.

The key is set on the top of the speaker, and the surface of the key is covered with soft material. In addition to the commonly used playback control keys (pause/resume, previous song, next song), there are folder switch keys, battery mode, Bluetooth phone and M key (AUX and Bluetooth connection switch). The powerful function is my first impression of the Longines M600. I am also drunk when I imagine holding it to answer and make phone calls.

The nylon fiber woven mesh covered on the front of Longines M600 is different from the ordinary plastic mesh. It is dustproof and has a splash proof function. The splash proof function is very practical outdoors. It would be better if it could be fully waterproof. I think a little too much.

The side frame is made of plastic. You should pay attention to it when you often go out to use it. Otherwise, it will be hard to see after scratching. The speaker can be placed horizontally or vertically, and there is a large soft anti slip pad at the bottom.

On the back of the speaker, the hollowed out cavities on both sides are two bass passive units. It seems that the low frequency performance of the speaker is very good.

Open the rubber plug, which contains the TF card socket, power switch key, AUX socket, Mirco USB interface and USB power output port. Longines M600 can read TF content and support folder switching. Another feature is that it can be used as a mobile power supply, which is a rare feature of other speakers. I just didn't expect to set the power switch here. It's a little inconvenient to use.

2、 Sound quality experience

(The picture is quoted from the official)

Officially, Longines M600 is a 2.1 channel loudspeaker system consisting of a 3-inch woofer, two 2-inch full frequency speakers and two 90 × 60mm bass passive units. The 5-series chip of Texas Instruments can guarantee the 17W rated power output of Longines M600 speakers. The power of 17W is obviously too abundant for a small speaker of this size! 2.1 Channel also makes the speaker more suitable for scenes, not only listening to music, but also watching movies, playing games, and even square dancing.

The Longines M600 supports AUX and Bluetooth, which are also the mainstream connection methods at present.

At the beginning of the first day, I felt that the sound was quite dull, probably because of the new speakers, especially the small speakers. After several days of continuous auditions, the sound improved a lot, and the low-frequency performance was very good. The low-frequency speakers were close to the passive units, and the energy loss was also small. There was no feeling of being burnt, but it was clean, Low frequency is also a feature of this box, which is worthy of being a mobile subwoofer.

The performance of the other two full frequency speakers can only be said to be satisfactory, not as good as that of low frequency speakers. Longqin M600 is suitable for playing slow roll, DJ and dance music. Later, I changed Suhe's slow roll and some dance music, which is suitable for the expression of Longqin M600.

The built-in 8800 mAh battery, which is officially said to be able to play continuously for 7 hours, has not been verified. My personal experience is that it works well. After listening to it for several days, it still has power. Another special feature is that it can charge mobile phones and other devices, but only when the phone is turned off.

The nominal output can reach the maximum current of 2A. The measured current is 1.82A. Throw away the accuracy and attenuation of the instrument, this 2A is still worth affirming. It is both a speaker and a portable power supply. This concept is very good, and it is really a design that is convenient for users.

3、 Conclusion

Longines M600 has broken my impression of "cheap" domestic portable speakers. It is meticulously made, full of low-frequency elasticity, strong standby endurance, supports TF card expansion, and can also be used as a portable power supply. This is also the traditional virtue of domestic speakers. It has powerful functions, but I don't know why Longines has not added the traditional FM radio function, The Bluetooth connection also enables speakers to better connect with other devices, such as micro projection and TV, and bring good audio quality experience when watching blockbusters and playing games. Another use, I think you have also thought of, is to dance square dance. Longqin M600 can turn on the sound very loud without breaking the sound. It is very suitable for square dance.
