Wide frequency range, good battery life, fine-tuning of sound using the proprietary app.

Over-ear full-size headphones from niche manufacturer Sennheiser offer an advanced-class solution for demanding audiophiles and quality sound enthusiasts. The model is notable for its combined connectivity, supporting three methods — two wired options with a mini-Jack (3.5 mm) and USB-C (including detachable audio cables), plus Bluetooth v 5.2, with a special BTD 700 dongle.

The Sennheiser HDB 630 headphones are equipped with 42mm dynamic drivers operating in a wide frequency range of 6 to 40000 Hz. They are Hi-Res Audio licensed and provide a very detailed and balanced soundstage, which allows for fine adjustments via the branded mobile app. A strong point of the model is the active noise-cancellation system adaptive ANC, which effectively blocks external noise.

There is also a transparency mode for clear background and ambient sound audibility, supports aptX Adaptive codec, and additional useful options, including auto-pause upon removal. The model includes four built-in microphones, rotating cups, and a sturdy body that supports a comfortable fit, thanks to a flexible headband with soft padding and quality faux leather ear pads. The 700 mAh battery ensures great autonomy, up to 60 hours of music listening. A full charge cycle takes 2 hours, but there is also fast charging — 10 minutes of power gives another 7 hours of operation.
