The headphones are doing some fancy realtime DSP when listening to music and the quality is very well pronounced for professionally office headphones. Very nice love it I have a really hard time getting any type of headphones to stay in my ears so was excited to try this different style. My wife bought these for herself and found she wasn?t able to use her custom orthotics and had to resort to a different support that works as well. The braided cord prevents the cord from splitting unlike the plastic type. There is no middle ground, nor is there any point in paying more for something that will do the job exactly as the cheaper one does. All straps adjustable, even around the back of the heel. The rows are a little narrow but the construction is much sturdier this way. Because it isnt a full-size table saw, the tapered cut length available on this saw is too short to be of any real value using this tool. And even if it was the right size, the material could come defective and a guaranteed hole in each sole.
