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 Amazon.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 😎

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!

Light Headphones With Very Good Sound
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.

Pretty good, could be better
Got these as a holdover until I get some new PortaPros, and they're not bad at all for the price. The sound quality is good, a lot better than most of the stuff in the price range. The headband makes me nervous, it looks pretty thin, but it's held up and Koss stuff tends to be sturdy. Time will tell. I love the orange ear pads, they really make them pop out. Very comfy to wear for extended periods too. Very minimalist design, but I like it in this case. Well worth the buy, but if you have the extra cash to spend, I'd highly suggest getting a pair of PortaPros instead, as the sound quality and design is much better. That said, for a budget pair this is one of the best I've purchased.

Great headphones
Good sound, great look; however, note that sound does leak out very easily, others can hear what you are listening to!

Looks cool, sound sucks
I like the retro design of these headphones, but if you're buying them to listen to music, it's a bad idea. For podcasts it's ok. Compared to KOSS Porta Pro, they sound much worse. I ended up moving the Porta Pro drivers to the Retrospekt frame. And ordered orange Porta Pro pads from YAXI.

great if you have specific desires in headphones
these are perfect for me, a person who likes open back headphones and hates my head being squished by over-ear headphones. music quality is pretty good for such a small speaker. comfy to wear for long periods of time and don't fall off with a bit of head banging. a little staticy connectivity issue at the cord base by the jack but not enough to be a major con.

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.

Mejor de lo qué esperaba, la calidad del sonido te lleva a los 80 y los materiales son muy buenos.

I bought them for the looks hoping they sound as good as porta pro or kph40 but nah these are worse in sound.

密閉型、カナル型が前提となるノイキャンやワイヤレスもいいですが、気軽にMP3音源を聞くのに本当にそれって必要?排他的な聞き方をしたい時もあるけど、ウォークマンヘッドホンのような開放型で装着負担が少ないヘッドホンで移動中のBGMを楽しみたいと思い、数々安価なものを試しましたが音質が電話のような感じ。安いので仕方ないのかもとあきらめていたところでこれを見つけて試してみました。 KOSSといえど中国製ですがそれらとは別物でした。 ただのレトロレプリカではないですよ。 聴けばわかります。(周波数特性:30~17,000Hz インピーダンス:32Ωの表示があり)
