What reviewers said
ASUS ROG Delta 2
The ASUS ROG Delta 2 is a premium gaming-focused over-ear headset featuring large 50mm dynamic drivers, a detachable noise-cancelling microphone, and a remarkably long 110-hour battery life. It connects wirelessly via Bluetooth 5.2 or a 2.4GHz dongle, and its comfortable design makes it suitable for extended sessions. However, it lacks active noise cancellation, app support, and a custom EQ, limiting its versatility for non-gaming use.
- Pro:Extremely long 110-hour battery life
- Pro:Comfortable over-ear fit with large ear cups
- Pro:Detachable noise-cancelling mic for clear chat
- Con:No active noise cancellation or transparency mode
- Con:No app support or custom equalizer
- Con:Only AAC codec, no aptX or LDAC
Sennheiser HD 650
The Sennheiser HD 650 is a wired, open-back dynamic headphone built for serious home listening. It delivers a natural, detailed sound with a comfortable fit, though its sub-bass rolloff and bulky design limit it to stationary use rather than portable or active scenarios. Its replaceable cable and balanced connection option add to its appeal for audiophiles.
- Pro:Excellent clarity and natural tonal balance
- Pro:Very comfortable for long listening sessions
- Pro:Detachable cable and balanced output support
- Con:Noticeable sub-bass rolloff
- Con:Not portable or suitable for active use
- Con:High impedance requires a dedicated amplifier
