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
Sennheiser MOMENTUM True Wireless 2
Sennheiser's second-gen true wireless earbuds combine rich, detailed audio with effective noise cancellation in a premium, compact design. While the sound is polished and the feature set is solid, they lack multipoint connectivity and may not deliver perfectly neutral tuning for purists. Overall, they remain a compelling high-end choice for those prioritizing musicality and build quality.
- Pro:Excellent, refined sound quality
- Pro:Effective noise cancellation
- Pro:Premium, comfortable design
- Con:No multipoint connection
- Con:Sound not perfectly neutral
- Con:Touch controls can be finicky
