Ever since he visited the ZASV and PT80 music forums, he has started to play with earplugs. For a long time, he always feels more and more boring. The earplugs are not so powerful. They haven’t had the kind of surprises before, and they have decided to enter a thousand yuan after a long time. Active speakers, although the portable Bluetooth speaker is relatively hot recently, I feel that the portable speaker is not so forceful. After watching JD for a long time, I finally saw a speaker. Picking up, go in. . .
Box box is quite large, the weight is not too heavy, there are product patterns and some parameter information on the packaging, the box marked the two major features of the box to support Bluetooth and U disk playback. The box has a handle and it is convenient to handle it.
Open the outer layer, the inner package is a protective paper box, shock and drop resistance. The protection box will not be bumped during transportation. Speaker is intact
Speakers are 2.0 active speakers, the main and auxiliary two cabinets, a single speaker size is wide 15CM, high 24CM, deep 19CM, the size of the general desktop speakers. Speaker cavity with black imitation wood grain design, the appearance is still pretty good-looking, with wild colors and computers, TV have wood problems.
The speaker uses a 4" metal face low frequency unit and 1" wire film tweeter. There are three buttons in the upper right corner of the main box, the power button and the volume adjustment button.
The main box back panel has a knob to adjust, the top knob is to adjust the treble and the bottom knob to adjust the bass. Below the knob is a USB interface to support mobile storage input, below the USB interface is the audio output interface, and then below is the main and auxiliary box connection terminals, when the main and auxiliary boxes are connected to pay attention to the connection of the line, usually the silver side of the black terminal, Copper side is connected to the red terminal, as long as the two sides can be consistent, do not cross connect. The bottom is the power cord.
The big feature of this JBL CM102 speaker is that he supports a variety of playback methods, wired, Bluetooth and USB three modes, adjust the three modes is to press the power switch, blue (Bluetooth), purple (U disk) And green (wired). Bluetooth connection is more convenient, as long as the bluetooth open search device on the phone is connected, the connection is still very convenient, the signal stability is also very good, there are no problems in the indoor through the two walls, barrier-free transmission distance It is not clear that active speakers cannot be tested. Currently, the USB transmission mode only supports WMA and MP3 audio formats, and does not support lossless formats such as OGG, APE, FLAC, and WAV. If you want to use USB to play, first of all talk about lossless format into MP3 or WMA format, in general, 320K of MP3 is enough. I can't hear the difference in the quality of the lossless audio formats of 320K Mp3 and APE and FLAC.
The sound of the speakers is full and clear. The thickness of the vocals is moderate, slightly brighter, the high frequency is clear, the brightness is normal, and the extensions are good. There is a good performance on Laura Pausini-Un'emergenza D'amore, which made me listen to the single loop. Several times. The details of the instrument are not rich, and they are still in place for rock and roll. Bass thanks to the 4†metal surface LF unit, which has a certain depth and elastic dive, the knob is recommended to adjust in the middle, too small to feel the bass is too stiff, too much sound is too stuffy, every wall is rumbling Treble knobs are recommended for treble knobs in the two-by-two and two-thirds positions, too little voice is too boring, too much, the sound is a bit sting, the sound style is suitable, popular, rock, pure music, classical, symphony is not too Suitable for.
to sum up:
Advantages of the product: attractive appearance design; variety of playback methods, cable, Bluetooth, USB. Bluetooth transmission stability. The sound is full and powerful, shocking enough.
Disadvantages of the product: Functionality: USB mode is not compatible with audio files in lossless format, the performance of the sound field is not large enough, and listening to the classical symphony is still somewhat inadequate.
In general, it can be considered as a thousand-dollar choice. It is worth considering.
