I was advised to get some kind of anti-radiation headphones. There is some controvery that the use of bluetooth and wired headsets and cell phones can contribute to physical changes in your brain and hearing. You can read all about it online on your own, but I am here to tell you about the quality of these headphones (earbuds, actually). Doing some research, the DefenderShield seemed like a good choice. It was designed by a telecom engineer, and audio quality is a big deal to me. The reviews were pretty good, too, so I took a chance and bought them. When I got them, I anxiously hooked them up to my laptop and opened iTunes to play some songs and test them out. I was expecting a real hollow sound, but BOY was I surprised!The bass response was excellent, as was the treble. I even compared them to my Sennheiser earbuds, which now sounded tinny compared to these. Now there's one caveat. You have to remember that this is different technology than traditional headphones/earbuds, so some songs do sound a bit hollow but it really wasn't too bad. I even went as far as to order another brand of anti-EMR earbuds to compare......and they were horrible! Those were very hollow-sounding, but they were half the price, too. You get what you pay for. Downsides. I can only think of one, and it's similar to other reviews. The earbuds do fall out more easily than traditional ones. BUT...these come with 3 sizes of rubber ear adapters. Try all three. Also, the right size can make a difference in the sound quality, so do try all the sizes. To sum it all up, don't even think twice about this. There is a reason they are almost double the price of all the others; they are the best. Just get these. You won't be disappointed. And you'll be saving your brain from all that EMR.
