Soundcore Liberty D1200
The Soundcore Liberty Buds are semi-open earbuds that prioritize comfort and awareness of surroundings. Sound quality is widely praised as excellent, especially after EQ, and the ANC is considered surprisingly good for the open design, though not as effective as in-ear competitors. The biggest point of contention is the fit: while some users find them secure and comfortable for all-day wear, others report that the earbuds feel loose and fall out with minimal movement, despite trying different ear fins. Additional minor complaints include the lack of wireless charging and an occasional weak sound output that may require a firmware fix.
Pros

- Secure fit for many users
- Great app with customizable controls
Cons
- Fit is inconsistent and may be loose
- Earbuds may fall out with movement
- ANC less effective than in-ear competitors
- No wireless charging
- Occasional weak sound output
