KRK monitor headphones. I think the sound quality is comparable to standard monitor headphones from brands like SONY and AKG, but I didn't feel like there was anything particularly distinctive about them. I purchased them used about a year ago and used them occasionally, but I'm selling them to declutter. They have a rating of 4.27 on price comparison websites. ■ About the product ・Operation confirmed.
