These are very comfortable and great sounding headphones. They aren't exceptional for this price range, but very good and something to consider if you otherwise like the style and features.

Several years ago, I started buying a similar product ( same ingredient, same strength, same company) from my dentist....for about three times the price! This stuff works, without a doubt. I have the professionally fitted whitening trays, and with this product, I can get my teeth to look almost TOO white. Be careful how strong a concentration you use, though, bc it can make your gums sting for a day or so. That happened to me after the third application with this 22%, but for me its worth it bc I love the results.

Great reels going to replace 10 quantum reels for half price if you are undecided try one I guarantee you will buy more
