What reviewers said
Sennheiser CX SPORT
The Sennheiser CX Sport true wireless earbuds are built for active use, offering a lightweight, secure fit that stays put during workouts. They deliver a lively, bass-forward sound with support for aptX and AAC codecs, plus Bluetooth multipoint for convenience. While their performance is solid for exercise, the price is on the higher side, and real-world battery life may fall short of the advertised six hours.
- Pro:Secure, stable fit during intense movement
- Pro:Energetic, bass-heavy sound signature
- Pro:IPX5 sweat and splash resistance
- Con:Battery life often below the rated 6 hours
- Con:Pricier than comparable sports earbuds
- Con:No active noise cancellation
Soundcore Liberty 4 Pro
The Soundcore Liberty 4 Pro pack a hefty feature set into a budget-friendly wireless earbud package, including adaptive noise cancellation, LDAC support, multipoint connectivity, and wireless charging. They deliver solid sound with crisp treble and effective call quality, though the charging case can feel gimmicky and prone to fingerprints, and spatial audio falls short. Overall, they're a well-rounded value pick rather than a flagship-level performer.
- Pro:Strong active noise cancellation
- Pro:Wide codec support including LDAC
- Pro:Multipoint and wireless charging included
- Con:Charging case feels gimmicky and smudges easily
- Con:Spatial audio performance is weak
- Con:Battery life is average for the price
