Review: Supremely musical, absolute bargain :) - Bought these "elsewhere" as these have only become available on desertcart UK from March 2025. Had been after a pair of light, small headphones for walks out etc for some time, as I always find the performance of "wireless / bluetooth" headphones disappointing, regardless of price. Thought I'd take a chance at £24 as loved the retro look also. Had these a couple of months now and couldn't be more pleased !! Even without any eq'ing via my phone, these sound great - crisp and dynamic and just completely "musical" without being boring hi-fi analytical or swamped with bass. They "really" sing when applying even a small amount of EQ - punchy, alive, dynamic with a big wide stereo soundstage - don't expect ear-splitting volume or bass that makes your chest vibrate .... but for someone who has a fairly pricey home setup and being a musician, music is a massive thing for me - these little Koss' are simply SUPERB - I would happily of paid 4 or 5 times the price. HIGHLY RECOMMENDED !!
Review: A Design Flaw. - Love the retro look of the headphones I didn't expect the sound the be amazing but it's okay. One design flaw is your hair gets caught in the adjustable headband very easily.
