[Preface]

With the popularization of smart phones in recent years, various corresponding connection device technologies have also been developed significantly, and Bluetooth speaker technology has benefited greatly from this. The technology in terms of sound quality, sound color, battery life, material quality, cost performance and other aspects has also been greatly improved. Thank you for trying out a Roentgen M600 Bluetooth speaker Love to play computer games Platform.

Longines Audio was established in Shenzhen in 2009, and has been a national high-tech enterprise focusing on digital audio development for seven years. Longqin has always adhered to the product positioning of elegant design, superior sound quality and ultimate technology, and has striven to create highly portable and reliable audio products. Brand positioning: "delivering noble fashion art with elegant design", product positioning: "noble design, high-quality material selection, ultimate technology, superior sound quality".

This Longines M600 is a new product of Longines Sound Company in 2016. How does it perform?

[Unpacking and detail display]

▲ The packing box was unexpectedly large.

▲ The package is very simple. The commonly used hard carton is not used, which is slightly thin and slightly deformed under violent transportation.

▲ The back and side are the technical parameters and functions of audio, such as voice broadcast, mobile power supply, card reader functions, etc.

▲ Open the packing box, and there are thick shock absorption foam omnidirectional packaging products inside.

▲ The shock absorption foam space is very compact, and the frame amount is small, so as to avoid damage to the sound caused by vibration.

▲ A family photo of Bluetooth speakers and accessories, including USB power charging cable, 3.5mm AUX audio cable, instructions and a product card. The quality of the attached wire is pretty good, and the material is soft.

▲ The speaker is of fine workmanship and rectangular design, with a size of 250mm * 147mm * 69mm. The front is covered with a splash proof nylon fiber silk dust-proof mesh, which feels good. Elegant gray color looks low-key without losing texture, and looks very classy.

▲ Solid keys with clear identification are easy to use. However, there is an obvious click sound when using it. If you can use the touch button, it may show more B grid.

▲ The bottom is a full-size anti-skid shock pad with good effect. But it is usually carried with a handle. In order to facilitate placement, it would be better to have a non slip pad on one side.

▲ There are obviously two passive units on the back, and the upper and lower parts in the middle are waterproof rubber covers and product nameplates.

▲ Below the back rubber cover are TF card slot, speaker switch, AUC input hole, charging hole and USB output interface.

▲ There is a brown leather handle on the side, which is convenient to carry. The leather texture of the handle is natural and soft, with the logo of "Longines" printed on it.

[Function and Use]

Longines M600 has three connection modes: 1. Bluetooth; 2. TF card; 3. AUX cable, focusing on Bluetooth and TF card.

1. Bluetooth: Bluetooth connection is very simple. After opening the speaker, press the "M" key to select the Bluetooth mode, open the mobile phone Bluetooth to search and connect, and the connection speed is fast.

2. TF card: TF card supports 32G at most and MP3, WMA, WAV, APE, FLAC full format decoding, greatly expanding its scope of use. After inserting the TF card, press the "M" key to select the card reading music mode, and the speaker will automatically read the music in the TF card. What I particularly like here is the function of "folder switching". In the TF card, you can create different music folders, such as "nursery rhymes", "crosstalk", "pop music" or "rock and roll". You can switch through the folder button to meet the different needs of your family.

▲ Since the whole speaker has no status indication other than the Bluetooth status indicator and battery power indicator, it uses voice prompts very humanized, including prompts such as switching between different modes and low power. The Bluetooth 4.0 transmission used by Longines M600 speakers is very powerful, with stable quality and longer distance. In the room, two walls can still play smoothly.

▲ The Langqin M600 Bluetooth speaker weighs 1.3KG, which is as heavy as a thin notebook. This is because four 2200 mAh batteries are built into the speaker to form an 8800 mAh battery pack, which makes the Longines M600 have strong enough endurance. According to the actual test with the mobile phone stopwatch, after being fully charged, the battery only went down one grid after nearly 5 hours (the volume was 20% - 50%, and the playing content was children's songs, rock and roll, and audio novels, about the same time), and went down two grids after about 8 hours.

▲ The splash proof and dust-proof net makes it suitable for more life scenes, whether it is placed on outdoor grass or hung on trees. However, the volume should not be too loud, which is easy to disturb people.

[Audio quality]

▲ Longines M600, built-in 2.1 channel speaker system, 20W Texas Instruments 5-series Xincheng chip, 17W rated power, one 3-inch woofer and two 2-inch full frequency speakers, and two 90 × 60mm passive woofers on the back. This hardware standard reflects the sincerity of the manufacturer for a Bluetooth speaker.

▲ The rated power of 17W brings enough energy, which is measured in the indoor environment and reaches 104 dB at the maximum volume.

▲ The music type I like is mainly gothic metal, and I also listen to some heavy metals such as hard rock. This Longines M600 is still very popular with me. It uses the patented technology Turbo Bass dynamic bass technology of Longines. Compared with ordinary Bluetooth speakers, its bass performance is good, and it also has a certain depth of diving. When it is held in the hand, it has a very strong shock, It gives people a feeling of full energy. The built-in 2.1 channel performance is commendable, and the performance of mid-range and treble is satisfactory. The disadvantage is that the resolution is not enough. When the music is large, it is easy to confuse the layers. Of course, the requirements for a 399 yuan Bluetooth speaker cannot be too high.

▲ Usually, I play some nursery rhymes to my baby, but the requirements for sound quality are not high. Longqin M600 is competent.
