Review on Bose QuietComfort 25 Acoustic Noise Cancelling Headphones with 3.5mm Wired Connection for Apple Devices - Black by Akihiko Kichiro ᠌

The model is intended for those who put the quality of active noise cancellation in the first place - in this field, the QC25 has no competitors at all. For example, the model is great for people working in open spaces, or just sitting next to colleagues who are constantly talking. Pros below: 1. The best noise canceling among the active noise canceling headphones. When you put them on for the first time in the subway, train or airport, your jaw naturally falls off, the noise is so drastically suppressed. 2. Comfortable, can be worn all day. 3. Sound. At the level of headphones for 5-8 thousand. Embellished, bright, engaging. 4. The ability to operate without a battery, and therefore without noise cancellation, as normal "passive" headphones. Cons: 1. Due to the operation of the noise reduction in the first place, there may be a feeling that the headphones emit an ultra-low rumble, which unpleasantly "presses" on the ears. Then either you get used to it, or the conditions of the external environment change. In short, it irritates a little and only at the beginning of use. 2. A dramatic drop in sound quality when noise reduction is turned off. The sound deteriorates so much that, in fact, it makes sense to use these headphones only with noise cancellation turned on. Probably, the battery is used not only for noise reduction, but also for active sound processing in general.
