Since the time when I was a wee lad, Ive become a slave to the sub-par keyboards that have been allowed to roam the earth. I popped one in my Bose 25 headphones and it supplied more than 30 hours worth of energy. They look nice despite the abuse he heaps on them, he likes the velcro since tieing shoes slows him down, and he never complains his feet are tired or sore. ????????VectorWorks???????????????????? Bought for my 7 year old But will have to get a size up for sure. Im sure those who are music purists may disagree with some of this but for the money these are very superior headphones. cant figure out why these were so reasonable but, ill take them. Sounds like air conditioners are blocked fairly effectively. The only complaint I can think of at the moment, is that I need to remember to turn off device when done, even if putting on the charging dock, otherwise the device remains connected via bluetooth.
