What reviewers said
Sennheiser CX
The Sennheiser CX True Wireless earbuds deliver a solid, bass-forward audio experience with dependable connectivity and strong call quality. They offer a good set of features for the price, including app-based EQ, wear detection, and a compact charging case, though their sound lacks the openness of pricier rivals. Overall, they're a competent choice for everyday listening, but increased competition has made them less of a standout in the budget tier.
- Pro:Excellent call clarity with four microphones
- Pro:Customizable sound via app EQ
- Pro:Good battery life with quick charge support
- Con:Sound tuning is bass-heavy and less spacious
- Con:No active noise cancellation
- Con:Design feels somewhat plain and bulky
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
