This is aim toward sports or high mobility travelers. Wearing it on with the rubber hook shape ear-loop takes time, I wished the used memory frame/wire helps to speed up the process and adapts to different ear sizes. A concept that is follow by brands like Audio Technica, KZ and high end Audiophile IEMs.

You can run, jump and fly, it will stay put in your ear with the rubber hook. If you worry about the cable dangling around, they did provide a tab for cable management (essentially shortens the length) but it can go missing easily so a better alternative would be great. | Calvin Pixels | Calvinpixels | Treblab RF100 Review

The cable is 74 cm long earbud to earbud, Treblab should make it short to 40-50cm range like some of their competitors(less dangle and cut production cost). The control center house the mic, playback/calls button and volume control. The package comes included with total 6 eartips size (3 silicon and 3 foam), a round shape hard carrying case and usb cable for charging. I recommend the foam for sporting activity. Weighs 20 grams. | Calvin Pixels | Calvinpixels | Treblab RF100 Review

Battery rated to last 9 hours, our test lasted 7 hours and 20 minute on 5th volume on iPhone 6. Charging take around 2 hours. It’s water resistance IPX6 rating. Running on bluetooth 4.1 with support of Qualcomm’s aptX. Our second IEM where it has magnets to keep the bud attach when not in use. The range maxed out at 11 meters line of sight. Sound isolation is very good as it goes deeper into the ear canal.

Audio quality


Pia Mia – Do It Again
Bass is okay tho it eats into the vocal a bit and the vocal feels muffled or pushed back. Bass has the energy (air pressure).

Tiaan – Be Okay
Low bass frequency is powerfully, you can feel the vibration and fades well. Again feels muffled for vocals. | Calvin Pixels | Calvinpixels | Treblab RF100 Review


Violinder Raindrops
Piano/Violin tones tone good sounding more “warm”, short on shine at the highs (I personally prefer super sharp sound type). The bass/drum overpowers the piano/violin tones.

Ed Sheeran – Touch n go
Guitar tones is okay but I feel it ends quickly especially towards the guitar chord vibrations, vocal tonality through the song is good tho I wish for more clarity.

Overall the IEM is well suited for modern pop and bassy songs, it does well in that department. Vocal requires some in-device equalizer tuning as naturally is muffled sounding so boosting the mid frequency is recommended. The bright side is the foam and ear hook works well for sports especially rock climbing and does well in rain (tried running 20 Km under the rain?).
