Sound quality:
I directly compared this with the Sony MDR-ZX300AP Sound Monitoring Headphones (2x the price) and pair of Panasonic light weight headphones (1/2 the price). The Sony and this Koss had fantastic sound quality. Of the two the Koss was better, first it had greater clarity of sound and spoken word was more distinct and less muddy. Additionally this one was louder at he same volume setting. All else being equal a louder headphone indicates more money was put into the magnet and sound coupling efficiency-- hinting at the good engineering. The slightly cheaper panasonics were no match in sound quality, compactness, construction quality, though they get good marks for being the lightest (and thus highly comfortable for casual listening)
ergonomics
Unlike the typical modern style of headphones this one has a plain (adjustable) spring metal bar over the head. This was actually slightly more comfortable than the Sony for the simple reason it gripped my ears more firmly so the top bar did not have to sit on my head-- something I find to be very uncomfortable. Now I've have more comfortable over the ear cans with padded head bars and also even more comfortable on ear ones as well but these were quite satisfactory while being much less bulky or heavy than heavily padded cans
portability
The spring metal is not to make it cheap but is actually an engineering innovation. First, it's adjustable and heavy duty. This is to support the feature that when you fold this thing up you can compress then head bar. it becomes a tight coiled spring and there are two little hooks on the ear peice hinges that hold it tightly coiled. The ear peices then hinge into this folded state and the whole thing fits in a the tiniest space I've ever seen for headphones with only two hinge points. (your typical folding headphones either have more fiddly hinges to break or are novelty items with fragile plastic swivel joints that won't hold up to travel abuse in your backpack. others that use the same spring metal style are more flimsy and usualy cheap all over/)
The only thing on these that looks flimsy is the foam ear coverings. They are thin, feel delicate and I expect I will tear them or they will oxidize and wear out. I see they actually sell new coverings so this is probably why.
Styling
Now the styling of these is definitely weird and combined with the metal head peice makes them look throwback if you set then next to a beefy Beats or Bose headphone. But I'd say the engineers defintiely triumphed here. It sounds good, it is rugged, it's compact and it's reasonably comfortable. The price is remarkably low for such quality.
Conclusion:
They put their money in these were it counted. They stole design styles from cheaper headphones but toughened them up and paired them with quality components. I really wasn't expecting these to be better than the Sony monitors but they were.
these of course can't match the audio isolation of a quality branded over-the-ear noise canceling headphone but for $20 these are as good as you can get.

Most Durable and Reliable Behind the Neck Headphones I've Been Able to Find
KEY POINTS FOR CONSIDERATION: * Behind the neck or on top the head are both options; and the ability to fold flat(ish) is nice. * Some people have complained about the hook option (for folding & locking) hurting their ears, which it did for me, but I used a pliers to fold those pieces down (see pics). A wire snips did not cut them which impressed me. * The foam pads kept falling off but the Sunmns 2 Inch Foam Pad EarPad Ear Covers I already had fit great so you may want to consider purchasing those. * I'm not used to wires going to both earphones so sometimes I get frustrated with tangled wires.All that being said, since Sony's MDR-G45LP Behind the Neck Headphones are no longer being made, I've searched for years for a durable and reliable set of corded behind the neck headphones. I've tried at least four other brands and none of them lasted more than 3 months, some less than 1 month.It is important to note that Amazon does not list these headphones if you search "behind the neck headphones." I found them though a Google search and went back to Amazon to purchase them.I am SO happy to finally have a brand of behind the neck headphones that I like nearly as much as the Sony MDR-G45LP!!! I love my tiny MP3 players so I need corded headphones which are becoming more difficult to find.

Sono molto pratiche, leggere e versatili il tutto con un ottimo audio sia per volume che per profondità del suono, insomma, il suono è davvero molto equilibrato.
E’ possibile utilizzarle anche dietro alla nuca ad archetto, io le riacquisterei ad occhi chiusi, peccato che dopo 6 anni il loro prezzo sia raddoppiato.
