What reviewers said
CMF Buds 2
The CMF Buds 2 are a budget-friendly true wireless pair that deliver punchy, bass-forward sound with a lively treble, making them engaging for music lovers. They pack a surprisingly rich feature set for the price, including hybrid ANC, transparency mode, multipoint connectivity, and long battery life, though call quality in noisy settings and limited codec support hold them back slightly. Overall, they're a strong value pick for those prioritizing fun audio and versatile features over premium extras.
- Pro:Punchy, bass-heavy sound with lively treble
- Pro:Excellent battery life with case (55 hours total)
- Pro:Hybrid ANC and transparency mode for the price
- Con:Only AAC and SBC codecs, no LDAC or Hi-Res support
- Con:ANC is decent but not class-leading
- Con:Call quality suffers in loud environments
UGREEN HiTune S3
The UGREEN HiTune S3 is an affordable open-ear TWS option that prioritizes comfort, lightweight wear, and practical extras like low-latency gaming mode and multipoint connectivity. While it delivers solid battery life and keeps you aware of your surroundings, its sound profile is a clear compromise—especially in bass and overall fidelity—and there's no companion app for tuning. It's a sensible pick for casual daily use, not for audiophiles or bass lovers.
- Pro:Very lightweight and comfortable for extended wear
- Pro:Low-latency game mode works well for gaming
- Pro:Good battery endurance for the price
- Con:Sound quality is weak, especially bass and detail
- Con:No app or EQ adjustments available
- Con:Maximum volume may feel limited in noisy environments
