The Sony WF-1000XM3 Truly Wireless and Sony WF-SP800N Truly Wireless are stronger in different areas. The WF-1000XM3 have a more premium build, a more effective ANC system, and a better-balanced default sound profile. The WF-1000XM3 also support NFC pairing and have more options in the Sony| Headphones Connect app, including surround sound configuration. On the other hand, the WF-SP800N have a more comfortable, stable fit, leak less audio, and last longer on a single charge, though their case holds one charge to the WF-1000XM3’s three, so the WF-SP800N’s total battery life is less.
