Why we picked the winner

The Space Q45 delivers noticeably stronger active noise cancellation that actually competes with headphones twice its price, blocking out airplane drone and office chatter more effectively than the WH-CH720N. Battery life is exceptional at 50 hours with ANC on versus Sony's 35 hours, and the sound signature is warmer with more present bass and mids that most listeners prefer for everyday music. The app offers better EQ customization and the build quality feels more premium despite the similar plastic construction.

The Sony WH-CH720N earns its place if you value a lighter headset that disappears during long wear sessions—it's about 30 grams less—and Sony's DSEE upscaling does genuinely improve compressed audio from Spotify or YouTube. Multipoint connectivity works more reliably on the Sony, and some users prefer its flatter sound for podcast listening. If you already own Sony devices, the ecosystem integration and brand trust might justify the slightly weaker ANC performance.

Frequently asked questions

Which has better noise cancellation, Space Q45 or WH-CH720N?
The Soundcore Space Q45 has significantly stronger ANC, blocking low-frequency rumble and mid-range chatter more effectively. Real-world testing shows it silences airplane cabins and coffee shops better than the Sony, which struggles with persistent background hum. If noise cancellation is your priority, the Anker is the clear winner.
Is the Sony WH-CH720N worth it over the Anker Space Q45?
Only if you prioritize feather-light comfort for 8+ hour sessions or already own Sony devices for seamless pairing. The CH720N is noticeably lighter and its DSEE upscaling does improve Spotify playback. However, you're sacrificing 15 hours of battery life and considerably weaker noise cancellation for that lighter build.
Which sounds better for music, Anker Q45 or Sony CH720N?
The Anker Space Q45 delivers fuller, more engaging sound with punchier bass and richer mids that most listeners prefer for pop, rock, and hip-hop. The Sony offers a flatter, more analytical signature that some prefer for classical or podcasts, but lacks low-end impact. The Anker's LDAC codec support also gives it an edge for hi-res streaming.
Can the Anker Space Q45 connect to multiple devices simultaneously?
Yes, the Q45 supports multipoint connectivity for two devices, though some users report it's slightly less reliable than Sony's implementation. You can have it connected to your laptop and phone simultaneously, but occasional manual re-pairing may be needed. The Sony handles device switching more smoothly in practice.
