Tronsmart Onyx Prime review: All play and some work make this an excellent pair of earbuds
Tronsmart's Onyx Prime true wireless earbuds tout longevity in terms of battery life and a charming, comfortable design. Pair that with rich audio, an IPX4 waterproof rating, and a low-latency mode, and you've got the right recipe for a standout pair of earbuds. However, there are some misgivings that cannot be overlooked.
