This is Edifier’s affordable wireless sport IEM. It has water/sweat resistant so you can clean it after a sweaty run in the park. The package comes included with a hard carrying case, micro-USB cable, total 3 eartips sizes and 1 earfins.

Sound isolation is good as the sound tube goes deep into the ear canal. The sound tube is 0.6cm long and is angled 60 degree for better in-ear grip and comfort. Thus you can use them without the earfins; shaking your head aggressively won’t make it fall off. The earfins are big in size compare to market average but is comfy and does its job well, wished Edifier makes them slightly shorter and soft material like how Sony sport IEM fins are. Maybe in the future version we will see it.

Jaybird-style cable management tab.

The flat-style cable length is 50 cm but they included a cable management tab similar to the Jaybird X series that shortens the cable to your desired length so it won’t dangle around (check our video). Control center is located on the right side; houses the mic, call function/media control button and volume rocker. It has a thin profile and the buttons are clicky. It uses Bluetooth 4.0 with build-in NFC function with maximum stable line-of-sight range of 11 meters. Microphone is good overall.

Our battery life test uses the iPhone 6 at 1 volume bar we manage to get 6 hours and 30 minutes. Yes is that loud even at 1 volume bar, other brand usually average out at 3 to 5 volume bar. So is good that Edifier amp-ed it up.

Audio quality

Pop/EDM:

Tiaan – Be Ok

  • Low bass frequency is superbly energetic, you can feel the air pressure moving in your ears.
  • Low bass frequency is well bodied and doesn’t eat into the vocal but overpowers it slightly.
  • No low bass frequency distortion.
  • Low bass frequency fades butter smooth.

Pia Mia – Do It Again

  • The bass is highly energetic and solid body.
  • The bass doesn’t eat into the vocal but overpowers it slightly.
  • The bass fade smoothly at the 2:05 mark you can hear obviously while it fade.

Vocals/Instrumentals:

Violinder – Raindrops

  • The Piano/Violin tone are well bodied and has good sharpness at the high frequency but it lean towards the warm sounding type, not the sharp-crystal-pitch sound but still good in my book. No extra shine needed just ok for now (and for the price).
  • The bass/drum overpowers the piano/tone slightly but doesn’t cause any muffle sound to the piano/violin tones, there is a clear separation between them.

Pentatonix – See Through

  • Mitch Grassi’s Hi-pitch male Tennor vocals perform well at the high frequency, good amount of sharpness (borderline).
  • Each singer in the group vocal can be identified easily, vocal humming and beatboxing is 3 dimensional feeling. The mid-range is top quality when in comes to the sport IEMs market.

I would say this Sport IEM is good from the low bass frequency to the upper-mids. I feel audio quality wise is much better than the W293BT that we review (here) especially at the mids to the high, is clearer. The IEM is also much powerful even at lower volume (audible levels). Check out some of our edifier review here. I hope to see Edifier updating this sport IEM with active noise cancelling or improve the battery life (the battery place at controller side + buds) in the future since they got the basics right.
