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
Skullcandy Aviator® 900 ANC
The Skullcandy Aviator 900 ANC is a feature-packed over-ear wireless headphone that prioritizes convenience and longevity over audiophile-grade accuracy. With adaptive noise cancellation, a massive 60-hour battery (50 with ANC), fast charging, and multipoint Bluetooth, it's a solid daily driver for most listeners. However, its sound signature has noticeable quirks that may not appeal to purists, and the lack of an official IP rating is a minor letdown.
- Pro:Exceptional battery life with quick charge support
- Pro:Adaptive ANC with effective noise reduction
- Pro:Multipoint Bluetooth 5.x for seamless device switching
- Con:Sound tuning is unconventional and not neutral
- Con:No official IP rating despite sweat resistance claims
- Con:Only AAC codec support, no aptX or LDAC
