A beautiful wireless IEM that can be easily mistaken for an Apple product (they call it earphone but doesn’t look like one). The housing is made out of Aluminium with a soft matte exterior finish that is nice to touch. The flat style cable is 54cm long from earbuds to earbuds that can be untangle easily. The control center houses the microphone, volume rocker and call/media controls on the right side. The left side house the battery and the micro USB charging port. I wish the the battery box and the control center follow a similar design to look more symmetrical and refine. The IEM sits flush into the ears and looks good, no dumbo look.

I find it hard to use the the metal clip to manage the cable from dangling around as I often wear collar shirt. I wish Sudio had follow Jaybird style of cable management. Sound Isolation is good, it can be improve if the the tube is 1mm to 2mm longer.

Comes with a leather pouch, metal clip, USB cable, quality assurance card and total 4 earbud size. Its using a 10.2mm dynamic driver. Bluetooth 4.1 with a 10 meter range from our test it can go 12 meter before signal degradation happens. Total weight is 14 grams, lightweight.

Audio quality

Pop/EDM:

Pia Mia – Do It Again
The bass has the right amount of energy and body, kept under control thus no distortion, eats tiny bit into the vocals. 2.10 mark, bass vibrations is really good.

Tiaan – Be Ok
Low bass frequency is punchy, no distortion, right amount eargasm and well bodied.

Vocals/Instrumentals:

Violinder – Raindrops
Drum/Bass more noticeable than piano/violin, violin lack shine feel muffled.

Ed Sheeran – Touch N Go
Vocal range is nice, vocal humming is good, guitar tone needs some shine. Vocal slightly muffled additional EQ setting needed to feel better.

Pentatonix – See Through
Group vocal humming is super eargasm, tho Mitch Grassi hi pitch voice at 0.42/0.52 is flat, need more shine in the high range.

Overall the Bluetooth Wireless IEM feels safe (little muted/muffled) for the mid range but does well in the low range. This is great for Pop/EDM and bassy songs. If their improve the cable management and have longer tube, can be use as a wireless bluetooth sport IEM.
