Review on Sony - C400 Wireless Behind-Neck In Ear Headphone White (WIC400/W) by Jagat Buana ᠌

The lack of cables is decisive, and it makes up for other drawbacks, but audiophiles may be disappointed by the result. "Chinese" phone owners should exercise caution; I tested Xiaomi and Honor and found barely perceptible but still perceptible noise and interference; this is a known issue in principle. These have a pleasant sound quality on my Samsung and Sony devices. Pros: +Excellent ergonomics + Decent build quality + Good autonomy (15 hours out of the box at above-average volume) + Good as a headset + I stopped yanking my headphones out of my ears with my bag Negatives: - jarring degradation of audio after earbuds are plugged in. Even though it improved after getting warmed up and changing the equalization, it was still quite bad. If the bass isn't "pounding," then it's not loud enough.
