Treblab J1 Review | Bluetooth Sport Earbuds
This is Treblab’s sport IEM featuring IPX 6 water and sweat resistant as well as magnetic ends. The package comes included with the hard carrying case, 1 cable management tab, 3 pair of earfins and 6 pair of eartips (3 silicone and 3 foam). The foam eartips and earfins does well for high intense movement and activities. Tho I wished they include 2 of the cable management tab so the cable can be shorten like Jaybird’s way.
The control center is located on the right side, houses the microphone which is clear during call, the charging port and the typical 3 button array. The buttons have a tactile bump great to identify each button and the buttons are easy to actuate.
The cable does not touch the face and the mic is near the mouth area, great for calls. Passive (hardware based) sound isolation is good as the sound tube goes deep into the ear canal measuring 0.7cm.
It’s powered by pair of 8mm Neodymium Dynamic Drivers. Uses Bluetooth 4.1 for connectivity with a maximum stable line of sight of 11 meters. The rated battery life is 8 hours. Our battery is based on the iPhone 6 at the 1st volume bar after maxing the volume on the IEM first, lasted us 9 hours on a full charged.

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 has zero bass distortion. The subtle bass vibration fades a little quick. Low bass frequency is well bodied. The low bass slightly overpower the vocals.
Pia Mia – Do It Again (standard bass)
Bass is energetic and presence, you can feel the air pressure. The bass fades with a decent drag especially at the 2:05 mark, stronger vibrations would be nicer. Bass doesn’t overpower vocal much and feel somewhat balanced, clear separation between the two. Bass is well bodied. EDM tones sounds safe and shy.
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. Little more shine at the highs would be nice as the tones now feels reserve or safe. Bass/Drums slightly overpowers the Piano/Violin in term of audible levels, tho there is clear separation between the two.
Pentatonix – See Through (Hi Frequency vocals/Separation)
Mitch Grassi’s hi-pitched-male Tenor vocals perform good at the highs with the right amount of shine, little more would be nicer. 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 sport IEM performs well from the low bass frequency up to the upper-mid frequency. The highs is acceptable but feels safe and not expressive enough, Treblab N8 sound better at the highs.
