EarFun Open Jump

The EarFun OpenJump are suitable for both sporting activities and everyday office use, and were particularly comfortable for spectacle wearers when tested. Their sound is versatile and pleasantly airy, even if the bass range could do with a little more depth. However, this can be better balanced using the equaliser app. Street noise is occasionally picked up by the other person when making calls.

The OpenJump from Earfun are the second cheapest headphones in the test field and yet are better equipped than the rest in one respect: Earfun is the only manufacturer to build a coil for wireless charging into the case. This means you can charge on the go without a cable using a suitable smartphone...
