Our Verdict
Anker SoundBuds Curve Wireless
Sony WI-SP500 Wireless
The Anker SoundBuds Curve 2017 are much better sports headphones than the Sony WI-SP500 Wireless. The Anker offer a much better value for your money, thanks to their better sound quality, more comfortable and stable fit, and their long battery life. On the other hand, the Sony have NFC pairing and a slightly better wireless range. The Anker are the better choice for sports and most use cases, especially in the budget range.
