I just got to know Longines M600 because of its shape. In fact, it is somewhat similar to B&O BeoPlay A2, which is very attractive. Longqin, a brand belonging to Shenzhen Longqin Audio Technology Co., Ltd., is a young enterprise established for 7 years. Its product line should be positioned as a low-end market. This time, it launched its flagship product, the M600 speaker, which has changed its previous product's youth and beauty, and is more stable and qualitative. In terms of appearance, the transformation is very successful.

I just got it and found that the size of the outer box was still quite large, but unfortunately it was violently lost by the express delivery. In fact, if you don't want to add another transport package, the sales package directly facing consumers should be made stronger. This three-layer 140 high-strength paper should not be able to bear the load, although it has good foam protection, But consumers' first impressions of the products will be greatly reduced.

Both the front and back product drawings are decorated with water splashes. I think there are two implications: one is fresh, and the other is its splash proof function.

Among all the functions, my favorite is the switchable folder and the mobile power function.

The speaker is surrounded by thick foam, and even the portable part is filled with foam. Its internal damage prevention is still in place. The accessories are simple, just one audio cable and one power cable A simple manual is of course necessary. Because after careful study of the manual, we know that it is a long press of the up/down button, which is the opposite of the usual volume button.

Holding the speaker, I feel that it still has a certain weight. It's just right for boys, but not for girls.

The workmanship of the speaker is very fine, and the protective cover on the front has a primary waterproof effect. It is recommended that the material of this protective cover should be harder. Now because of its large area, it will be pressed in the middle. I am very worried about its anti-collision ability. If I am not careful, it will directly damage the internal speakers.

The hand strap with its own leather has enough texture and is heavy but convenient to carry. Although the surrounding area is made of plastic material, it doesn't have obvious plastic feeling with elegant gray color.

These two on the back are the sound generating positions of the passive bass speakers.

The 2.1 channel loudspeaker system consists of a 10w 3-inch woofer and two 3.5w 2-inch full frequency loudspeakers, which work together with the two bass passive units on the back to produce a shocking bass effect.

The cover above has a good sealing effect, and is also designed to be splash proof. The switch, TF card slot, audio input hole, power input and output hole are all protected inside.

The top is the position of its control keys and status lights.

The volume key shares a key position with the switch key. The setting of short press is for switching, and long press is for volume adjustment, which is contrary to the usual operation. Press the mode switch key to switch the sound source and there is a voice prompt. Here is a suggestion. The volume of the voice prompt cannot be adjusted. The default volume is still large, which frightens the baby.

The anti slip mat at the bottom also takes into account the effect of shock absorption. No wonder it is said in the publicity that it can also prevent the body from vibrating. The body has a clear sense of vibration when encountering bass. If it was not for this mat, the speaker would really go out on its own!

Bluetooth connection is also very convenient. After switching to the Bluetooth mode, there is no need to set up a pair separately. You can directly connect to the M600 after mobile phone search. It's very convenient!

When I got it, it showed that there were still 2 batteries left. After a few days... There are still two batteries. Of course, although the listening time is not very long, the endurance is also very satisfactory. It's just that the power indicator is red, always thinking it's a reminder of low power!

Its folder switchable function is particularly suitable for playing music by category, especially for children's favorite songs and fairy tales. Daddy must give a compliment!

In terms of hardware, the 2.1 channel speaker system and the 20W Texas Instruments 5-series chip with DSP digital sound effect processing fully meet the needs of good sound quality.

After listening to the voice and instrument respectively, the sound effect is very satisfactory, especially the bass part, which is amazing, thick and not muddy. The shock feeling in the hand is indescribable, and the volume is also suitable for outdoor use. And it takes into account the role of mobile power supply, also suitable for playing an emergency role outdoors.

In short, M600 has given me a new understanding of Longines, and I am looking forward to his next work.

PS: It's better to add a display screen, of course, when the price is not increased.
