At first glance, the M15 seems to be a reduced version of the Edifier M1 series, which is equally bright and white.“Skin tone”, simple shape, but is it really the case?

A closer look will reveal that there is a clear difference between the M15 and the previous Edifier M1 series. The first is the shape and structure. Compared with the flat body shape of the M1 series, the M15 is closer to a boat shape, with the front panel relatively straight and the rear panel presenting a clear arc. The M15 shell is similar to the M1 series. It is finished with high-gloss material in one-time injection molding, which is very delicate and feels good. The specially treated Edifier M15 has excellent abrasion resistance and the same color table. It will not fade after long-term use. It does not need any spray decoration, and it follows the new concept of health and environmental protection. In addition, the seams of the front and rear panels of the M15 are very tightly welded.

The high-efficiency digital power amplifier provides sufficient power output for the speakers, and the overall sound quality is also very good. If you close your eyes and listen, you will never imagine such an excellent sound coming from such a small speaker.

In addition, a white strip-shaped guardrail is used on the upper part of the two speaker units, which can effectively protect the unit, and inadvertently make the overall shape look like a pair of big flashing eyes, a very imaginative design.

The outstanding design of M15 lies in its built-in SD card socket and direct reading function of common audio formats. Although this SD card direct reading function is not new, it has been adopted by the Edifier C6 before, but the introduction of this function makes the portable speaker no longer restricted by the sound source, further highlighting the connotation of portability.

In terms of control, M15 has designed the ultra-popular playback control buttons nowadays, and the use of rubber materials makes the buttons feel good. In addition to the power button and volume adjustment button, with the introduction of the SD card direct reading function, a music switch button and a pause/mute button are also added, which can play and adjust the songs in the SD memory card, compared to the previous mini speaker control The operation is more intuitive and convenient. In addition, the M15''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''''s power switch adopts a wave switch, which can completely cut off the internal power supply, reduce internal loss, and extend the service life.
