My new go-to head strap - Use my promo code "BRIANSLOAN" for an extra 5% off.

I've been using Kiwi head straps for years now. They didn't disappoint with the new K4 Boost. The recessed adjuster knob, the shortened charging cord, the ability to fast charge, and the continued padding are all great. The only thing I would like now is the ability to charge it like the SPC battery head strap with their dock. But maybe a new dock will come out soon anyway.

I got about 3 extra hours of game time with this. The charge time as mentioned is really fast especially when you use the 45W charger made by Kiwi.
