I have had a set for 3 years now they sound great . Problem is if you are pron to have heavy ear wax build up you better q tip your ears before you use them , And then clean them out . the 3 piece kit they give you .You will need too use the longest one of the 3 insert it and move it around pull it out . Then use the u shaped one and give it a couple of turns . Belive me the tinyest piece of wax can cause loss of sound . Also the wire is not coated very well if it gets caught in your jacket zipper it might short out . I have had 2 shorts and have had to send them back 4 other times to be cleaned out and have new filters put in , As i am typing this i am waiting for them to come back and it takes at least 2 weeks because big ear does not make the product there the middle man . The people at big ear are very nice people on the phone and try to do the right thing on 2 occasions they did not charge me . And they just retooled if you want to call it there product to a different filter becuse of the ear wax problem . The salesman at the show which is the owner can sell you the brooklyn bridge he is that good . P.S. When i first recived my set there was air flowing into my ear i called them up (There in C.O. )and she said someone would get back to me 2 hours later the owner calls me and said i am in N.J. i will drive to you house and shoot you another pair at the time i lived in Staten Island which was 25 minutes away . i said give me the adress to your hotel and i will come over . The only reason he was there was because he was doing another show . So that gives you some back round on the co. Are they worth the cash i have nothing to test them against so i can not give you a yes or no . To all that purchased the product i hope you dont have a WAX problem and watch out for your zippers .
