What reviewers said
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
Tronsmart Onix Prime
The Tronsmart Onix Prime are hybrid true wireless earbuds that pair a dynamic driver with a balanced armature for detailed, Hi-Fi-style audio, boosted by aptX Adaptive support. They deliver a long 40-hour total battery life with the charging case, but lack features like ANC, transparency mode, and app customization. Their straightforward design focuses on solid sound and extended playtime rather than extra smart features.
- Pro:Hybrid dual-driver setup for rich, detailed sound
- Pro:Long 40-hour total battery life with case
- Pro:Fast charge gives 2 hours from a 10-minute top-up
- Con:No active noise cancellation or transparency mode
- Con:No companion app or custom EQ
- Con:Only one microphone on each earbud, limiting call quality
