What reviewers said
Audeze Maxwell 2
No summary yet - we haven't aggregated enough reviews.
Sennheiser Massdrop HD 6XX
The Sennheiser Massdrop HD 6XX are open-back, wired over-ear headphones offering a neutral, mid-focused sound signature with excellent clarity and well-matched drivers for accurate imaging. They are lightweight and comfortable for long sessions, with a detachable cable and included adapter, but their 300-ohm impedance means they need a decent amplifier to perform at their best. As a budget-friendly take on the classic HD 650, they deliver strong audiophile value rather than bass-heavy impact or portability.
- Pro:Accurate, neutral sound with strong midrange clarity
- Pro:Lightweight and comfortable for extended listening
- Pro:Detachable cable and 3.5mm adapter included
- Con:High 300-ohm impedance requires a capable amp
- Con:Open-back design leaks sound and offers no isolation
- Con:Limited soundstage and not very impactful bass
