I mainly use my ipod for work out on aerobic equipment at the gym -lrb- treadmill , stepper , bike , etc -rrb- . I have be look for some earphone to replace the one Apple give you with the ipod . although those offer decent sound , they be damned uncomfortable and make my ear hurt after 30 minute -lrb- I do not understand why can not Apple include comfortable earbud with they product ! -rrb- I do a lot of research before buy these V-Moda Bass Freq earbud . at first I be go to get some Sony earbud , but after read about the problem with the cord spontaneously disintegrate , I decide against it and go for the V-Moda instead . all I can say be : WOW ! I think the sound from the Apple earbud be pretty good , but it be nothing compare to the V-Moda 's . as you would expect , the sound be rather `` bassy , '' but the high be also quite crisp . I would not say it be perfect , but really it be extremely good . I be very very pleased with this purchase ! I mainly use my ipod at the gym . as you can imagine it get pretty noisy there and I wind up have to crank up the sound on my ipod to hear the music well . these V-Moda 's fit in my ear extremely comfortably and actually provide a great deal of noise blocking . all that extra noise create by the other treadmill and bike around I be 70 to 80 percent block out ! I be quite amaze . and this allow I to hear the music clearly , therefore I do not need to crank the volume of my ipod so high . the music sound so much better than usual that it motivate I to exercise longer -- because I be really enjoy the sound of the music so much ! since they be earbud , you do have to place they rather deeply into you ear canal to achieve the correct bass and noise-blocking effect . you may need to fiddle with it a little bit to get all the bass effect . but the earbud be a not uncomfortable . in fact , I wear they for a hour and forget that they be on . extremely comfortable ! I have only own they for a couple of week so I can not comment on they durability , but I be very careful with my stuff so I expect they to last a long time . I plan to order one or two more pair . oh , and by the way , I also order a pair of iLuv 301 because they be inexpensive -- the sound do not even begin to compare . the iluv 301 's produce a tinny little sound , whereas these V-Moda Bass Freq 's be terrific . it be like compare a transister radio to a 100-watt speaker . overall I give the V-Moda Bass Freq 's five star for quality , sound , noise blocking , and a good value for the money !
