Lab Partner Jr. v1 or v2? How to tell them apart
The Lab Partner Jr. v2 (LPJ2) replaces the original Lab Partner Jr. v1 headphone and headset (LPJ1 and LPJ1m), which are now discontinued. Same headphone, same sound, same ear cushions. The one change is the cable socket: the v2 takes the same plug-in cables and SpringBoom™ microphones as our K6d and BKd headphones, so one set of spare cables now fits all three. Need a microphone? Add the SpringBoom™ mic to your LPJ2 order, with a 3.5mm or a USB-C plug.
| v1: LPJ1, LPJ1m (discontinued) | v2: LPJ2 | |
|---|---|---|
| Earcup socket | Small round hole, flush with the bottom of the earcup | Raised, eye-shaped port on the bottom of the earcup |
| Cable plug | Long, slim 3.5mm plug that goes deep into the earcup | Short, standard 3.5mm plug with a chunky white grip |
| Replacement cables | CBL-LPJ1 Lab Partner Jr. v1 cable | Any K6d / BKd cable: standard 3.5mm, 110° angled, USB-C, 3.5mm magnetic breakaway, USB-C magnetic breakaway |
| Microphone | LPJ1-MIC SpringBoom™ microphone (v1) | SpringBoom™ media microphone: SPD-MIC, 3.5mm plug or SPD-MIC-C, USB-C plug |
| Ear cushions | LPJ-CUSH replacement ear cushions fit both versions | |
Not sure which one you have? Look at the bottom of the earcup where the cable goes in. A small round hole, flush with the shell, means v1; a raised, eye-shaped port means v2. The cable plug tells you too: long and slim is v1, short with a chunky grip is v2. Order cables and microphones for the version you have. Questions? Contact us and we will help you pick.
