Very disappointed, it only decreased the noise slightly. I will probably try to remount the pump to see if I can solve the problem

I purchased these so that I can listen to my music while working or easy to take a phone call when my phone is not on me. I wanted something lightweight and easy to use . They are made of ultra-light shape memory alloy. Super easy and comfortable for wearing all day. I hate dealing with wires dangling around my neck and getting in the way so this definitely takes care of that. The battery is long lasting with Up to 10 hours / music time, 300 hours standby time and 2 hours charging time. They only weigh approximately 4.58 ounces which is super light to me. The earbuds stay in my ears without them sliding out of place. Bluetooth convenience so no more plugs into my phone that I would have to carry in my pocket etc. They are very simple and easy to synchronize with my iphone5s cell phone. They work great and they sound amazing.
