What reviewers said
Audeze Maxwell 2 ANC
No summary yet - we haven't aggregated enough reviews.
Sennheiser HD 660s
The Sennheiser HD 660 S is a wired, open-back dynamic headphone that delivers a neutral, mid-focused sound with accurate vocals and instruments, though bass impact is limited. It offers a comfortable fit and a wide soundstage, but its open design provides virtually no isolation, making it best suited for quiet home listening. While it performs well with a range of music, it benefits from decent amplification to reach its full potential.
- Pro:Accurate and natural midrange for vocals and instruments
- Pro:Comfortable for long listening sessions
- Pro:Wide soundstage with good imaging
- Con:Very poor isolation due to open-back design
- Con:Limited bass impact
- Con:Upper mids can sound harsh at higher volumes
