The sound quality is not noticeably better than via Bluetooth, despite the twice as high frequency range (4 – 40,000 Hz) with jack connection and amplifiers. This speaks first of all for the wireless connection. The sound evaluation is critical according to the price class.

The powerful NC disturbs the sound of the Sony headphones a little. But does one notice this in everyday life with every piece of music? – I don’t think so.
