I bought these to use on my daily commute on the train, specifically picking the "over-the-ear" style to try and block outside noises...somehow these little jobbies AMPLIFY all high-pitch noises to unbearable levels. People talking and the train noises are much louder with them on than with them off. I find this true anywhere that there's high frequency noise: malls, buses, crowded sidewalks...pretty much only good at work and at home, not what I needed. There are many good qualities to these headphones, but the few bad make them nearly worthless to me.PROS:Good sound quality over bluetoothEasy setup with my phone/tabletFold-up nice and smallGood volumeGood microphone for phone callsDurableAttractive lookingCONS:Amplifies high-frequency noises to unbearable levelsThe buttons are easily confused when I'm operating them while they're onSmaller than I imagined
