Our Verdict

Bose SoundTrue Ultra In-Ear

KZ ZS10

The Bose SoundTrue Ultra In-Ear are a slightly better headphone overall than the KZ ZS-10. The Bose have a more comfortable earbud fit, which most will prefer over the in-ear design of the KZ. They also have an in-line remote and a mic so you can more easily use them with your phone, and they're more convenient when gaming. On the other hand, the KZ are better built, with a replaceable cable. They also have a variant with a mic that should perform a little better than the Bose. The KZ also look a lot more premium than the Bose, especially for their price.
