[EX Q]: The sound is horrible. You have these little 'headphones' that are supposed to go on over the ears and they don't even fit my 12 year old. He was so upset because it didn't work for them. No matter how tightly you put these on, his glasses pushed them off at every turn. They wouldn't stay put. Don't waste your money. I returned mine immediately. Bummed kids = big headache.
[EX A]: Bad review

[EX Q]: Not only do this things look great and sound great, the bass is amazing!!! they are very comfortable to wear, but after about 30 days I got a short in them where they connect into your iphone or ipod. Don't waste you money on these
[EX A]: Bad review

[EX Q]: I've had these filters for about a month. I can notice an improvement in air quality, but no changes regarding our overall health. However, we use the filter everyday, so it's not like we're breathing cleaner air. This isn't to say that there aren't other better ways of providing clean air, though. Still, it seems worth it and we love being able to feel good knowing that we're doing something healthy with our money when using this..
[EX A]:
Good Review
