These headphones are absolutely amazing for $20! As somebody who has suffered with an ear wax issue for the last decade, I was still very reluctant to purchase and try this product. We just have a very specific issue to deal with here. Only the glass beads are in the plastic organizer with no wiggle room whatsoever. If you are ordering from here and would prefer to get the same consistent trainer - do not order from here. Disliked color, advertised as black gray. Make sure your source audio is set no higher than 75% or the muddiness will be even more pronounced. Its super heavy duty, so thank god for the handle and wheels; almost reminds me of a traveling suitcase with the extended handle that is installed in the rear. No matter what size I used, the plugs wouldn?t stay in my ears longer than 15 minutes. I have already walked several city blocks in them and they feel great.
