overall a amazing deal . for the cost the sound quality be absolutely amazing , crisp , clear , but lack the bass you would get with more expensive and larger con headphone . the only downfall to these be the design and comfort , which at they worse be not really that bad . the headband catch on you hair all the time and be not convenient to take on and off because the adjustability be not very convenient . the other adjustability problem be the `` comfort zone '' adjuster to make the earphone tighter or looser on you head , very inconvenient . but overall you can not beat the quality for the price . if you want the best headphone for under $ 50 , you find they with these , although they have a few imperfection , the value to quality ratio be unbeatable . great value !
