What reviewers said
Bluedio Fi
The Bluedio Fi is a budget-friendly true wireless earbud packed with extras like touch controls, USB-C charging, and an auto play/pause sensor, plus support for aptX and AAC codecs. However, while it offers a lot of features for the price, it stumbles in core areas like wireless stability and audio quality, making it a mixed bag for everyday use. Its lightweight, IPX5-rated design and decent call clarity are highlights, but the lack of app support and mediocre sound keep it from being a standout.
- Pro:Good call quality with CVC noise filtering
- Pro:Lightweight and comfortable for extended wear
- Pro:USB-C charging and Bluetooth 5.0 for convenience
- Con:Unstable Bluetooth connectivity at times
- Con:Sound quality is below average for the price
- Con:No app support or EQ customization
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
