Our Verdict

Sennheiser HD 450BT Wireless

Sony WH-CH720N Wireless

The Sony WH-CH720N Wireless came out after the Sennheiser HD 450BT Wireless with some benefits of time like better battery performance, more app features, and more refined controls. The Sony also have virtual surround sound and a comprehensive app with EQ. Their ANC is a bit more effective. The Sennheiser have small ear cups that limit some people's ability to get a good seal, and that also impacts their sound. Nevertheless, the Sennheiser can yield higher quality aptX audio and low latency audio with aptX-LL. Their app includes EQ, but it's simpler.
