What reviewers said
AKG K271 Mkii
The AKG K271 MkII is a wired, closed-back studio headphone that prioritizes accurate, workmanlike sound over flashy tuning. It offers a comfortable fit and a clean midrange, though its bass response is restrained and its plastic build feels less premium. This is a practical monitoring tool rather than an exciting consumer headphone.

- Pro:Clean, detailed midrange for vocal and instrument monitoring
- Pro:Detachable cable adds convenience for studio use
- Con:Bass lacks depth and impact, not for bass-heavy genres
- Con:Plasticky build quality feels somewhat fragile
- Con:Upper mids can sound slightly boxy at times
