Notifications:
They are without a earphone jack, they need a earphone jack on the audio source device( computer,laptop,etc) to work with.
These are USB powered with small output, sound volume cant compare with those expensive AC powered speakers with big output.
If the on wire controller is inconvenient for you to adjust the volume, pls try to adjust on the computer or the media player.
PLEASE PLUG IN THE USB AND THE AUX BOTH FULLY, OTHERWISE THERE WILL BE NOISES OR LOW VOLUME.
IN MANY CASES, NOISES OCCUR FROM BAD CONTACTING OF DEFECTIVE COMPUTER USB PORT OR AUX PORT. PLEASE MAKE SURE YOUR COMPUTER USB PORT AND AUX SLOT BOTH FUNCTION WELL, OTHERWISE THERE WILL BE NOISES.
THE CAUSE OF STOP WORKING MIGHT BE THE DEFECTIVENESS OF THE SPEAKERS, OR THE DEFECTIVENESS OF THE COMPUTER USB/AUX PORT AS WELL.
Amplifier IC is most important for the sound quality of small speakers. Cheap IC hardly can produce a clean and loud sound. Moloroll M4 adopted with IC PAM8403, of which the cost is very high for cheap small speakers, but can produce a clear louder sound with less distortion.
Drivers play a essential role for speakers. Drivers too small or too thin are difficult to produce a strong sound. M4 adopted high quality 2 inches full range drivers with additional magnets, to make sure the sound strong enough, or at least march their dimensions.
Moloroll M4 speakers are selected from many other models. Limited production costs and limited power supply( DC5V 2A) limited the sound fidelity and output of M1/M3/M5. We select less but worthy models.
Reviews which complaining cords too short are common. M4 speaker to speaker cords about 39 inches, AUX cord and USB power cord (from volume controller to plug ) about 43 inches, which may work well with most laptops or big size monitors.

Metal Mesh Many costomers had experiences that the drivers got damaged or ripped off when there were no protection for them. Each of the M4 driver is fixed by 4 screws,and protected by a metal mesh. |
Surface DealingMany small speakers are with flat original plastic colors, to save the cost. M4 surface is with fine rubber oil painting, just for a decent looking and better touch feeling. |
Passive WooferSince small 2.0 speakers without a main woofer box, many of them cant performance the audio bass part well. M4 with passive membranes at back side, they wont creat a super bass but at least could enhance some, better than without. The beats hit on a dram sound better than hit on a desk. |
Volume Controller M4 are with a handy independent volume controller, very easy to adjust the volume when enjoying the music or movies. |
