What reviewers said
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
Sony WH-XB900N
The Sony WH-XB900N is a wireless over-ear headphone that prioritizes bass-heavy sound and long-lasting battery life over neutral tuning. It offers a comfortable fit, solid feature set including multipoint and LDAC support, but its noise cancellation is modest and charging is slow. It's a reasonable pick for bass lovers who value stamina, though not a class leader overall.
- Pro:Very long battery life
- Pro:Comfortable for extended listening
- Pro:Supports high-quality codecs like LDAC and aptX HD
- Con:Bass-heavy sound can become muddy or overpowering
- Con:Noise cancellation is weaker than many rivals
- Con:Recharging takes a very long time
