I'm sorry, but how can US$20 equal "good", let alone "very good"?? Also, by "supergluing" "padding " won't the sound dynamics be effected?
Lastly, wouldn't Open phones be best in a vehicle environment where safety requires one to be sound aware of the vehicles, etc around you? Is it legal to wear headphones while driving, in your locale?
Cop: "Sir, didn't you hear the other driver "beeping"??
Headfier: No, I had my "closed" headphones on and the music turned up real loud!!
The reality is, even without headphones, blasting your music means you cannot hear 'Warning' sounds outside of your vehicle; and, in many locales it may be illegal. You, can certainly be found "at fault" by failing to heed a warning, because you couldn't hear above your loud playing music and/or using headphones!
