This technology is truly one of the best...and I've tried everything out there, including the expensive trendy ones - NO Comparison! MTX has created an excellent product that answers so many wants and needs of us audiophiles. First and foremost - comfort! I have very sensitive ears - both with sound and physical comfort - and they have met that need with their easily adjustable headphones and interchangeable earbud sizers. For the first time, this insomniac is now actually able to fall asleep every night listening to relaxing music...heavenly! Also, both the headphones and the earbuds help drown out other distracting noises. The awesome parrot head colors are most enjoyable! Definitely worth the investment!!
