To give you the help you need we need to know 3 very important things
1. What is your source? => This is what your playing them through be it a CD player PC ipod ect the device your playing music from
Why is this important?=> If your source is of poor quality no matter what you do they will sound bad and not give you the sound quality you want
2. What quality is the music or material being played?=> This is the bit rate of your material is recorded in the higher the bit rate the better the quality and the better it will sound when played though decent gear (if you have crappy gear well its still going to sound bad even if the source it good lol)
Why does the audio quality matter?=> If your songs for instance are like 128kbs in bit rate (like a mp3 you get for free and what not) it will sound terrible no matter what you do or what you play it with so getting good material like hi quality movies and music will make for a much better experience.
3. Are you getting a good seal?=> This is the fit of the earphones into your ear canal
Why is the seal important? The design of earphones allows them to channel sound into your ear canal through a seal by the use of the ear tips provided by the earphones and range is sizes for a better fit. If you don't have a good seal there will be a significant reduction is bass output and overall sound quality and little to no isolation at all depending on the design of the earphone.
Again i cant stress the 3 above enough because if any of the 3 are lacking in anyway it really is going to make your sound quality from them suck no matter what you do so read through it and give it a try as these really are great iems. So please give us feed back so we can help you out a bit and i see your a new member so welcome to head-fi and sorry about your wallet!
