This is a surprisingly comfortable headset with a great off feature - fold to close and turn off. It's loud enough and clear enough on use on a Moto Razr as well as a Samsung blackjack. the turn-on, turn-off boom microphone means your voice is crisp and clean on the other side. Sadly, it does not filter out wind noise (or anything else) so on a windy day or nosey environment, you will not be heard. But you don't expect sound baffles at this price. It is a steal for the price.
