What reviewers said
Cambridge Audio Melomania P100 SE
The Cambridge Audio Melomania P100 SE is a well-rounded wireless over-ear headphone with a focus on portability, offering an outstanding battery life of up to 100 hours without ANC and 60 with it. It delivers a premium feel and sound, though its bulky build and a bass-heavy default tuning may not suit everyone, and the noise cancellation performance is decent but not top-tier.
- Pro:Exceptional battery life, especially with ANC off
- Pro:Premium build and sound quality for the price
- Pro:Supports aptX Lossless and multipoint Bluetooth 5.3
- Con:Bulky and heavy design may cause fatigue for some
- Con:Bass is overly boosted out of the box
- Con:Noise canceling is inconsistent in varying conditions
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
