The Space Q45 headphones are very comfortable for a few hours at a stretch. However, if you break a sweat, you’ll likely not be able to wear them for an extended period of time.

The Anker Soundcore Space Q45 is a Bluetooth headset that connects to different Bluetooth codecs depending on the phone. The default is AAC, but there’s also support for SBC and LDAC if you enable it through the Soundcore app. The headset is charged via a standard USB-C cable.

Anker advertises a battery life of up to 65 hours with ANC off and 50 hours with ANC on. In our test, the headset achieved a battery life of 55 hours and 48 minutes, which exceeds these claims. The headset also supports fast charging, which means you’ll likely never find yourself in a situation where the Space Q45 is rendered useless by a dead battery.

The Anker Soundcore Space Q45 is a good noise isolation headset. It does a good job of blocking out conversations or music at low volumes, and it also supports active noise cancellation. The ANC is pretty solid, though it can’t match market-leading headsets like the Sony WH-1000XM5.
