This is Treblab’s sport IEM featuring IPX6 water resistant and has a magnetic ends as well. The package comes included with a hard carrying case, a charging cable, 3 pair of ear-fins and 6 pair of eartips (3 silicone and 3 foam). The foam eartips and ear-fins does perform well for high mobility movements. Though, I wished they included extra 2 cable management tab so the cable can be shorten like Jaybird’s way.

The Accessories

The control center is located on the right side where it houses the microphone, charging port and the typical 3 button array. The buttons have a tactile bump, which is great to identify each button and the buttons are easy to actuate.

The cable does not touch the face and the mic is near to the mouth area for better vocal pickup. This is great for those who is constantly on the move or multitask. The sound isolation is good as the sound tube goes deep into the ear canal. | Calvin Pixels | Treblab J1 Review | Bluetooth Sport Earbuds
The Hard Carrying Pouch

The Treblab J1 is powered by a pair of 8mm Neodymium Dynamic Drivers. It uses Bluetooth 4.1 for connectivity with a maximum stable line of sight of 11 meters. The rated battery life expectancy is around 8 hours. Our battery life test is based on the iPhone 6 at the 1st volume bar after maxing the volume on the IEM first. The battery lasted up to 9 hours on a full charged.

Tiaan – Be Ok (Low bass frequency)

The low bass frequency is superbly energetic and highly notable, you can feel the air pressure booming in your ears. The bass doesn’t eat into the vocals and it has zero bass distortion. The subtle bass vibrations fades a little too quickly while the low bass frequency is well bodied.  Overall the low bass slightly overpowers the vocals.

Pia Mia – Do It Again (Standard bass)

The bass is energetic and presence, you can feel the air pressure while listening. The bass fades with a decent drag especially at the 2:05 mark, though stronger vibrations would be nice.  The bass doesn’t overpowers the vocals too much and it feels somewhat balanced. There is a clear separation between the two. The bass is well bodied and the EDM tones sounds safe and shy in my opinion. | Calvin Pixels | Treblab J1 Review | Bluetooth Sport Earbuds
The Magnetic Ends


Violinder – Raindrops (High frequency instrumental)
The piano/violin tone sounds right and natural, it leans closer to the crystal-clear type not the warm-sound, I prefer the crystal clear type. A little more shine at the high frequency would have been nice because at the moment the tones feels reserved or safe.
 The bass/drums does slightly overpowers the piano/violin in term of audible levels, but there is clear separation between the two.

Pentatonix – See Through (Hi Frequency vocals/ Separation)
Mitch Grassi’s hi-pitched-male Tenor vocals performs really well at the high frequency with the right amount of shine. A little more shine would have been nicer. Each singer can be identified easily. Every diction and pronunciation is crystal clear. The vocal beat-boxing, echoing and humming is an eargasm but it does slightly overpowers Mitch Grassi’s vocal in the song. | Calvin Pixels | Treblab J1 Review | Bluetooth Sport Earbuds
With/Without The Ear-fins


This sports IEM performs well from the low bass frequency up to the upper-mid frequency. The high frequency is acceptable but it feels rather safe and not expressive enough. The Treblab N8 sound better at the highs frequency than the Treblab J1.
