Pros and Cons
2 PACK USB — What Stands Out
- The USB C earbuds Shaped to fit most users without strain. Smaller ear canals may need aftermarket tips. is comfortable and secure fit, includes 3 sizes of eartips (S/M/L) for replacement
- When you need to wear headphones again, you can also access them anytime
- The form factor fits naturally into routines like commuting, workouts, video calls, and late-night streaming. Buyers who commute daily mention that the unit disappears into their setup without constant readjustment.
2 PACK USB — Buyer Complaints
- The most common 90-day complaint is cable hardening near the connector or intermittent sound when the jack rotates. Daily commuters should budget for a replacement cable within 12 months.
- Plastic driver housings develop micro-creaks after repeated pocket storage. This is cosmetic but annoying. Metal housings avoid this but add weight.
TRAUSI Open Ear — What Stands Out
- 50 Hours of Non-Stop Audio: The earbuds plus charging case deliver up to 50 hours of total playtime
- Immersive Sound with Deep Bass: Custom-tuned drivers produce a wide soundstage with punchy low-end and crisp treble
- The form factor fits naturally into routines like commuting, workouts, video calls, and late-night streaming. Buyers who commute daily mention that the unit disappears into their setup without constant readjustment.
TRAUSI Open Ear — Buyer Complaints
- Buyers who switch between laptop and phone report dropped handoffs and re-pairing hassles. Multipoint works better on some chipsets than others. Check the Amazon Q&A for your specific device combo.
- After 8-12 months of daily open-close, some cases develop loose hinges or dirty charging pins. A quick alcohol swab fixes the pins; hinge looseness is permanent.
