Summary: This is one to the TOP Brands ("Boss"). However, you get what you pay for. This is their low-end / cheap product, and it shows. It generates an intermittent high pitch when using it. Stay away from this particular model and invest the $$ to get something more reasonable in terms of quality. I returned it to Ostock and they were VERY good about refunding me 100% ***. GREAT company - O'Stock!!!
Summary: Got these for my 2 kids 9 & 6 to replace the originals that came with our car. They work perfect for the kids & they say they are much more comfortable than the old ones. Auto-off feature is also good to have since they aren't perfect at remembering to shut them off. I tried them on as well & they would fit an adult as well no prob. I can't vouch for the audio quality, but they work great for long car rides!
