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

Have been using the headset for two years. I put audiobooks on it and listen to them. A total of 20 hours were logged while in "constant listening" mode. The earphone wire eventually snapped and stopped connecting properly with the phone after two years of constant use. Perhaps the Bluetooth module simply wore out. This issue has disappeared once I replaced them with brand new versions. When compared to their aliexpress counterparts, the microphone and speaker quality here is significantly higher. A better choice is Sony. Very suggested!
