Review: Replacing my comparable old Sony headphones. - These are really impressive for the price and design. I have a pair of old Sony MDR-005 that I wear when casually listening to my Walkman DAP around the house. These headphones sound much better. They have great range and are very clear. The bass is very full and strong while not being overwhelming. My Sony headphones are getting up in age so these will be the replacement and I am more than happy with that. I am a guy with a pretty big head and these fit comfortably, I forget I am wearing them. If you been considering these for the form and function I say go for it!
Review: Good quality for the price. - Already bought one-pair ... for the price .. pretty good quality.

### ⭐⭐⭐⭐⭐ Good quality for the price.

Already bought one-pair ... for the price .. pretty good quality.

### ⭐⭐⭐⭐⭐ Good Quality Retro Design Sony's style headphones
*by M***E on 14 November 2025*

The sound quality is very good, even if the frequency range spec says 30-17,000Hz. Light weight and comfortable. Yes, others can hear what you are listening to, like in the 80's. Best Sony's style 70's headphones I can find today. Bought this to match my newly purhcased cassette tape walkman.
