The silicone exterior thingy does well for Americans and Europeans with bigger opening ear size, not all Asians would find this a good fit as our ear openings are smaller. To fix the problem, a longer sound tube would actually help for it to stay in place. Calvin had to replace the short eartips come with the package with custom longer ones so it does stay in place and have better sound isolation. As the original eartip does have decent sound isolation but not the best.

You can power the earbuds by placing them in or taking them out of the case, or hard long press would do the trick. You can also use one sided if you want too. The multi-button only handles call, media and power control. Volume adjustment is done on your device, as that’s not a big issue as most true wireless earbuds user stay at one volume most of them time.

Technical Specification

Audio quality

Pop/EDM:

Tiaan – Be Ok (Low bass frequency)

Low bass frequency is superbly energetic and highly notable, you can feel the air pressure booming in your ears. It doesn’t eat into the vocals and no bass distortion but do hear at lower volume. The subtle bass vibrations fade smoothly. Low bass frequency is well bodied. The low bass overpower the vocals.

Pia Mia – Do It Again (standard bass)

Bass is superbly energetic and firm, you can feel the air pressure. The bass fade smooth especially at the 2:05 mark, the vibrations is good but no eargasm. Bass doesn’t overpower vocal much and feel balanced, clear separation between the two. Standard bass is well bodied. EDM tones sounds fun.

looks good

Vocals/Instrumentals:

Violinder – Raindrops (high frequency instrumental)

Piano/Violin tone sounds right and natural, leans closer to the crystal-clear type not the warm-sound, I prefer crystal-clear type. It has right amount of shine at the highs. Tone are well bodied doesn’t sound half-hearted.
 Bass/Drums slightly overpowers Piano/Violin in term of audible levels, tho there is clear separation between the two.

Pentatonix – See Through (high frequency vocals / vocal separation)

Mitch Grassi’s hi-pitched-male Tennor vocals perform very well at the highs with the right amount of shine, little more would be nice. Each singer can be identified easily. Every diction and pronunciation is crystal clear. Vocal beatboxing, echoing and humming is eargasm but slightly overpower Mitch Grassi’s vocal in the song.

This true wireless earbuds performs well from the lows to lower-highs, good all arounder IEM. If it had little bit more shine at the highs it can closely rival the Sony WF-SP700N that we review earlier.
