Koss TWS250i
In April of this year, Koss already earned an editorial recommendation for the smallest model in their Bluetooth in-ear series. Back then, it was the TWS150i that earned our recommendation thanks to their decent price-performance ratio. Now the next model up in the series reports to the kopfhoerer.de command centre for testing, and naturally, and they want to leave at least as good an impression as their predecessor – if not a better one. And of course, we were happy to give these little earbuds the chance to take the stage (or the ears, as the case may be) to try to impress us.

BT740iQZ - A somewhat unwieldy name for what are actually quite elegant headphones that the designers at Koss have come up with for their new Bluetooth model. With active noise-cancelling (ANC), integrated media control and hands-free function, as well as long battery life, these new over-ear headphones are designed to be a convenient audio accessory for all situations.
