What reviewers said
Kiwi Ears Spark
The Kiwi Ears Spark are open-style wireless earbuds aimed at active users, featuring a 17mm dynamic driver and Bluetooth 5.2 with SBC, AAC, and aptX codec support. They offer a lightweight, IP45-rated design with touch controls and a total battery life of 21 hours when including the charging case, though they lack ANC, transparency mode, and multipoint connectivity. Sound quality is generally praised for its clarity and balance, but the bass response is notably weak, and the large case and overly sensitive touch controls draw criticism.
- Pro:Comfortable and secure fit for workouts
- Pro:Clear and detailed sound for an open design
- Pro:Sturdy build quality with IP45 water resistance
- Con:Bass is thin and lacks impact
- Con:Charging case is bulky and heavy
- Con:Touch controls are overly sensitive and prone to accidental taps
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
