How We Tested This Product

Our rigorous, independent testing process

Purchased
October 2025
Testing Period
30 days
Tested By
Owen Cavill

We evaluated the TRAUSI earbuds over 2 weeks of real-world use, including 20+ hours of music streaming via Spotify/Apple Music on iPhone 15 and Samsung Galaxy S24. Battery tests followed standardized drains: continuous playback at 50% volume until depletion, with case recharges timed precisely (10-min quick charge verified for 4-hour output). Sound was assessed using frequency sweeps and tracks from AudioCheck.net, scoring bass/mids/treble balance.

For durability, we simulated workouts with 5km runs (heart rate 140bpm sweat test) and IPX7 submersion in 1m freshwater for 30 minutes, followed by functionality checks. Call quality involved 10 outdoor calls with ENC mic tested against urban traffic noise. Fit/security used 3D head scans and shake tests. Competitors like Anker P3i were side-by-side for direct comparison on latency (<60ms gaming) and multipoint pairing.
