This model offers the same great quality of that model - RP-HT21 - with apparently weak plastic but with a reasonable use you maybe have this headphones in good conditions for 7 or 8 years

Hard plastic is uncomfortable on head

The plastic looks very fragile and I didnt' realize the cords are very thin

Just hard plastic.

BUT, the materials used to construct them (apparently cheap styrene plastic, brittle and thin

The only problem is they feel like cheap plastic.

Only bad thing is it looks like it is build with cheap plastics, I don't know how long it will

These Headphones we're good, the plastic seems cheap but its okay, they're loud but not your adverage bass sounding

It is not a very good plastic

These are not headphones for audiophiles, but I love them for travel as they block enough sound to be useful in a car or airplane but are inexpensive enough that if they are lost or broken it is no big deal.

The minuses: They are misrepresented as over-the-ear.

I will recommend this product to anyone who loves t use headphones
