Langqin M300 is already the third small speaker I purchased. Of course not for my own use, but for the elderly mom and dad climbing outdoors. The first is the Longines X3, which was sold to Dad a few years ago. He often listened to music while he was walking. At that time, the small card speakers on the market were mixed, and the X3's sleek appearance attracted me. The second is the Longqin T900. At that time, the pickpockets were only used for rendering cool lighting effects. They found that the gameplay was very strong. Of course, it was also lost to the father to listen to music at home. The third station was today. To say the M300, mom and dad often participate in some outdoor trekking activities on weekends. The M300 is small and compact, with a portable hook. It is very convenient for listening to music on the way. Someone may ask me why I do not buy BOSE soundlink mini. The reason is very simple - poor.  After obsessed with HIFI, several devices have been continuously contacted in recent years. The recognition of music and sound naturally has a corresponding height. So, you don't have to worry, I don't think I'll shoot such a small speaker. Just briefly introduce his features and intuitive feelings.  The M300 gave me a personal first impression of being small, with 176 X 90 X 58MM measurements and a weight of only 275 grams. However, on the positive side, the cross-sectional area is smaller than that of the iPhone 6, official information indicates that the M300 is a pocket that can be stuffed Good sound. I tried it with LEVIS 514. Hey, I can really stuff it in. However, I personally think that it may be more appropriate to use a hook to hang on the waist or an outdoor backpack. The M300 is equipped with a “skin-lined†fuselage that can not be hung with its keys. It is a fine workmanship. Under the tight wrapping of the “skin texture†material, it is dust-proof, splash-proof and splash-proof, and can withstand a height drop of 1 meter. It is more appropriate for people to listen to music when performing outdoor sports.   Features M300 also has the same rich features as the T900, support for AUX IN, Bluetooth wireless, card playback, card reader features, hands-free calling and voice broadcast, in addition, actually with a USB sound card function.  Of course, parents only use the card to play music. Many functions have yet to be learned. The voice broadcast function is really good for the elderly, "Bluetooth mode, external audio source mode, USB sound card mode, Bluetooth is connected, Bluetooth is disconnected," and even "the power is not enough, please charge in time" and other information will be through the voice broadcast function To communicate to users in a timely manner. This feature, in my opinion, is especially affectionate for the elderly.  If it is young people may prefer Bluetooth. The Bluetooth function of the M300 adopts a 4.0 transmission module, which saves power and stability, effectively avoids disconnection for no reason, and can support 10-30 meters of wireless connection, sharing and exchanging music in the mobile phone anytime and anywhere.  In addition, if you use a laptop during a business trip, and the built-in speakers sound bad, do not put a langqin M300 around. With the USB sound card function, you can change the speakers to your laptop by simply connecting the speakers to your laptop.  The Longines M300 supports up to 32GB TF cards, which is apparently not large enough for some users. But given that the user community is most likely just listening to some MP3 files, 32G space is obviously enough. Of course, the M300 can not only support MP3, but also supports lossless music format decoding such as WAV, FLAC, and APE.   Sound quality The M300 uses two 3.5W full-range dual-magnetic loudspeakers for higher sensitivity and sound effects. At the same time, the M300 uses a large-scale low-frequency radiator to effectively increase the low-frequency sensation, with better dynamic response and lower low-frequency distortion. The 6V inductive boosting brings less electromagnetic interference and can carry a large current continuous output under higher boost conditions. M300 uses FT2820 Class G audio power amplifier, low power consumption, loud sound, better play anti-break sound effect.  In terms of sound, M300 has a good sense of low-frequency volume and strength, which has an inevitable relationship with the structure of the speaker. At the same time, Long Qin M300 has a good vocal performance, clear, natural, without breaking sound. Strings and pianos can also bring good musicality. This structure also leads to certain deficiencies, such as small sound fields. Usually go out to climb mountains to listen to enough songs to use, I believe this product's positioning and design considerations are also true.   to sum up Compact and portable, dust-proof, splash-proof and splash-proof, it is all-in-one and sounds good. The official suggested retail price of 299 yuan, the current Jingdong and Tmall official store has a special price of 149 yuan.
