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: Excellent purchase - These are Koss Retrospekt headphones and they are crucial for full Eighties nerdiness. I won’t go into the long, fairly harrowing story of how they got here, but if you want a pair it’s quickest to order them from the USA on desertcart.com (as opposed to .co.uk). The best sound quality version of these are the KPH40 but they have black ear pads, although orange ones can be bought separately, and a black headband. I had black earpads in the actual Eighties so they’re not wrong but I wanted the brushed steel headband and the orange pads. They have no microphone or volume control as headphones with these functions, such as my Bang & Olufsens, will only play in one ear when plugged into a Walkman unless the jack plug is slightly pulled out. Something about three lines vs two lines on the jack pin. But I’m just nerding aloud. Suffice to say, they are light as a feather to wear, far better quality headphones than they look and the listening experience is 100% authentic to the time, right down to the noise leak that would drive people on the bus to distraction 😎

### ⭐⭐⭐⭐⭐ Light Headphones With Very Good Sound
*by D***T on July 7, 2024*

I'm a bit of a headphone addict and snob. I prefer balanced and clear sound, not too high in bass. I have high end AKG's, and Audio Technica with a headphone amp and a huge variety of music. I also always want a light and comfortable pair for casual listening. These are perfect for that and the sound is remarkably good for the price point. They are also very light and great for long term listening. I fully expected to have to return them for poor sound quality or fit. Instead I immediately bought a second pair in case these go away for some reason. I've owned them eight months and they have seen a lot of use and are holding up just fine.
