The PX7 S2e delivers excellent sound with plenty of detail and a very fine resolution. The electronic noise cancellation is first-class and can compete with that of Sony. The over-ear sits comfortably on the ears, although its weight is a little noticeable. However, this does not detract from the listening pleasure. The features are really great.

The Beats Solo 4 are rock-solid on-ear headphones that should make Beats fans especially happy. However, even in the relatively narrow niche of on-ear headphones, there are some models, such as the Marshall Major V and the Teufel Supreme On, that offer a little more performance for significantly less money. So you're definitely paying a premium for the brand and the iconic "B" on the ear cup.

If you like on-ears, you'll love the lightweight and tight-fitting Beats Solo 4. The sound is great and operation is simple. The battery life is also impressive. Simultaneous charging and playback as well as the option for music via a jack round off the range. The most important settings are equally possible with iOS and Android, although Android has fewer functions.
