if you be look for a reasonable set of ear bud to go with you new mp3 investment , the v-moda bass freq 's be a good choice . I own sennheiser headphone of various model and have always like the way they sound and still do . my favorite be the cx-300 , which be what I want to compare the vmoda 's to , as they be closest in price and performance . let I say first and foremost that the cx-300 's sound brighter , the treble sound crisper , and overall sound a tad more precise than the v-moda do . however , in the bass and midrange the vmoda , be incredible ! nice warm high and mind numbing bass . if you listen to metal , rock , hip hop , or pop , the bass freq 's be fun as hell to listen to . if you like classical , piano , and the other mention genre , the senn may suit you need a little better . neither of these be audiophile earbud , and could not be at there price range , so if you be a stickler for perfection , look elsewhere . for the other 97 % of we that want good sound quality , and want something that give those goosebump , when we hear that certain beat . either of these make a great choice . neither lack in the bass department , but the vmoda never distort at the lowest frequency . the senn 's do on occassion . you can actually make the vmoda sound crisper with a slight adjustment of the e.q. in you player and both of these phone sound similar . it be all just a matter of preference , but you can not go wrong with either set . as far as reliablity go , I can see the senn outlast the vmoda as the senn look a little sturdier than the v 's do . only time will tell and I will update if something happen . I like the fact the v 's come with a silicone wrap to neaten thing up , but a case would have be even better . they both fit nicely in my ear and come with different size silicone , for different size ear . to sum it all up ... if you be look for a decent earbud look no further than either of these 2 set . if you be a bass junkie , go for the vmoda . if you want overall good sound go for either one . at $ 25 , they be both a steal and you will not be disappoint at all . Trust I , I have try everything and I just think pay hundred for headphone 's be insane . unless of course you be a audio purist , than by all means . do what you gotta do .
