Bose QuietComfort 45
Bose QuietComfort 45 wireless headphones with adjustable active noise cancellation, designed for immersive everyday listening with or without Google Assistant.
Description
The Bose QuietComfort 45 is a wireless over-ear headphone fitted with active noise cancellation technology. It aims to isolate the listener from ambient noise for immersive music listening, whether at home or on the move.
The noise cancellation system continuously measures, compares and processes external sounds to cancel them out with an opposing signal. Three noise cancellation levels can be selected via the Action button, allowing the headphones to be adapted to different sound environments. The speakers benefit from equalisation optimised according to volume, which maintains consistent sound quality whether listening at low or high volume. The headphones also integrate Google Assistant, activated by a simple long press on the Action button, to play music, receive text messages or get answers without handling your phone.
In terms of build, the headphones combine glass-fibre-reinforced nylon with corrosion-resistant stainless steel. The headband is covered in Alcantara, a material notably used in high-end automotive interiors, while the ear cushions are made of synthetic leather. The stated battery life reaches 24 hours of listening, with a 15-minute quick charge offering an additional two and a half hours of use; a wired cable is supplied to keep listening should the battery run out.
These headphones are aimed at those seeking everyday portable listening, on public transport, at the office or while travelling, and who wish to be able to adjust noise cancellation according to their surroundings. Users within the Google Assistant ecosystem will find a welcome hands-free capability, though it is by no means required to enjoy the headphones.
What to check before buying used
The synthetic leather ear cushion foams compress and crack over time, which degrades the acoustic seal needed for active noise cancellation: check their flexibility and the absence of cracks. The Alcantara-covered headband may show a shiny or pilled finish at points of frequent contact. Also test the three noise cancellation levels via the Action button and the responsiveness of Google Assistant, whose proper functioning depends on software updates that may be outdated on a used unit.
