This product is amazing! My office is right above a karaoke bar and my other neighbours have started some heavy renovation work. Hence we decided to buy this to test the noise cancelling function and it works WONDERS! It’s reduced the noise by so much that we can work through heavy drilling and the terrible singing from downstairs! We wish we bought this sooner. And at the price that it comes at, you’d be hard pressed to find a better deal. One other note; the earphones come with a quick mute/unmute denoiser function if you need to quickly listen to your surroundings.
