#629 OnePlus Buds 4: $114.00 TWS Amazon $114.00 eBay
Pros: True wireless buds with active noise cancelling, Bluetooth 5.4, LHDC alongside AAC and SBC, and IP55 resistance cover most commuter needs. Battery life is rated at 11 hours per charge and 45 with the case. Sub-bass sits 5.3 dB over target, which gives bass heavy listeners plenty of kick and rumble, and it matches the rating of the pricier Soundcore Liberty 5 Pro.
Cons: The extra bass bleeds upward with midbass 2.8 dB and low mids 1.6 dB above target, so vocals can sound thick, and the air band jumps 5.9 dB with a 6.5 dB peak at 8.1 kHz, adding a tizzy edge to cymbals. The resulting preference score of 63.5 trails the Creative Aurvana Ace 2 and ARTTI T10 Pro, both rated higher for less.
