Anker Soundcore Space Q45 vs Bose QuietComfort Ultra

The Anker Soundcore Space Q45 headphones are designed to significantly reduce ambient noise by up to 98% using an advanced upgrade-targeted active noise cancelling system. Featuring a 40mm driver with a double-layer diaphragm made from silk and ceramic materials, they deliver crisp treble and punchy bass for an immersive listening experience. Built for all-day wear, these over-ear headphones combine a lightweight ergonomic frame with memory foam earcups. They also support LDAC for Hi-Res Audio Wireless transmission, ensuring high-fidelity sound reproduction when paired with compatible smartphones and media players.

The Bose QuietComfort Ultra Headphones combine Bose's renowned noise cancellation with a new Immersive Audio mode that adds spatialization and head tracking to any content, creating a more three-dimensional listening experience for music and movies. An updated CustomTune sound calibration technology automatically adjusts audio and noise cancellation to the specific fit and shape of the wearer's ears each time the headphones are put on. With up to 24 hours of battery life (18 hours with Immersive Audio active) and a lightweight, plush design, they are built for all-day comfort during long listening or travel sessions.
