Bose's QuietComfort Wireless Noise Cancelling headphones offer high-quality sound and high tech features, with customizable settings and a variety of modes to choose from. However, some users have experienced a strange sensation in the cups and the sound profile is not as defined as some other headphones. Additionally, the headphones are not suitable for long periods of use due to their lack of bass. Despite these issues, the headphones are still a great choice for those looking for a reliable and comfortable set of headphones.
