What reviewers said
HiFiMAN He-R10d
The HiFiMAN He-R10d is a closed-back wireless over-ear headphone that pairs a 50mm dynamic driver with Bluetooth 5.0 and support for high-quality codecs like LDAC and aptX HD. Its sound is characterized by warm, punchy bass, clear imaging, and extended highs, making it particularly enjoyable for pop and R&B, though its tuning may not appeal to those seeking neutrality. While it offers solid technical performance and easy drivability, its build quality and comfort have been flagged as underwhelming for its premium price point.

- Pro:Excellent imaging and micro-detail for a closed-back design
- Pro:Supports high-resolution Bluetooth codecs including LDAC
- Con:Build quality feels subpar for the high price
- Con:Comfort is limited, especially for long sessions
- Con:Midrange can sound slightly recessed or hollow
Sennheiser HD 650
The Sennheiser HD 650 is a wired, open-back dynamic headphone built for serious home listening.

- 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
