Our Verdict
Sony WI-C400 Wireless
Anker SoundBuds Life
The Anker SoundBuds Life are better around-the-neck in-ears than the Sony WI-C400 Wireless. The Anker have a much better sound quality and a more premium and durable design despite their thin cables. The Anker also have a much better battery and latency performance when compared to the Sony. On the other hand, the Sony are more lightweight and have slightly better cable management. The Sony also support NFC, which makes pairing with mobile phones a lot easier.
