Karma: JBL Synchros S700 headphones

edited August 5 in The Clubhouse
I've had these for 4 years sealed brand new in the box and I finally opened them up earlier tonight. Tried them out for 5 mins and put them back in the box, so they are practically new. They sound good, but I have too many pairs of headphones.

Info: https://www.jbl.com/factory-refurbished/SYNCHRO+700.html


They're unique in that they have a built in rechargeable battery and an option to turn on what I'm guessing is a type of built in headphone amplifier/active EQ.

To enter the Karma giveaway, pick a number between 1-100 and post it here, the random number will be drawn next Saturday night the 11th.

    These don't really require a headphone amp since they're only 32ohm, and they also have that built in active DSP thing. They come with those three ring cables, I believe these headphones are primarily meant to be used with phones/tablets. So don't let not having a headphone amp prevent you from entering.
