Review on Koss QZ Buds Active Noise Cancelling Earbuds with In-Line Microphone and Touch Remote Control, Monitor Mode, Carry Case Included - Wired Earphones with 3.5mm Plug, Black by Alicia Lynch

I've had them for over a month and have used them both on the go and in the office. The sound quality of these headphones corresponds to the Koss signature sound, slightly bassy but clean. I like them in all genres, but they work best on rock, country, and electronic music. The noise cancellation is very good, what you will notice with the noise cancellation is that any loud noise is "cancelled" by speech-like sounds. a bit muted. This balances out things like airplane engines, office fans, and noisy ventilation systems pretty well. A single AAA battery lasts about 20 hours (I use rechargeable ones to cut down on buying extra batteries) and even if the battery dies you can still hear it with good sound quality, just no noise. noise reduction properties. Of note is the monitor button, which you can press in noise-cancelling mode to hear your surroundings. Think about it, if you're on a plane and you're asked a question, you can just press that button and the voice will be heard. Basically it reverses the noise canceling properties and is very useful in certain situations. The headphones come with a carrying case, compliant foam ear pads, silicone ear pads and most importantly, a lifetime warranty! All in all, excellent sound quality, noise cancellation, accessories and a lifetime warranty make this model a must-have for travelers or office workers.
