I've bought them before one month from a friend for 45 USD.
I find this headphones in excellent condition, without any scratches on the plastic parts, without any wears and cracks on the leather, no damages on the paper drivers . I'm not sure when they were produced (somewhen between 1972-1988) but they seem like brand new and sound excellent for me. They're like my kind of headphones.
The headphones from the present-days have a very large Frequency Response, for example between 5HZ to 45kHz, the SE-205 despite their limitet range between 20Hz to 20kHz have a very soft, warm, vintage sound, with very expressive 3D soundstage. I was very surprised when I put them at first time on my ears. The tracks of Dire Sraits, Diana Krall, Eagles, Kanzas, Dream Theater and many others sound dynamic and analogue through them. Also for me the SE-205 are very comfortable and great for long listening sessions.
One week ago I've decided to start some modifications on them for better performance. I've bought from ViaBlue in Germany a 6 meters of EPC-3, it is their silver earphone cable. The price is around 4 EUR per meter, also I bought two Neutrik NP3X-B, it is a 3 pole 1/4 professional phone plug and one Neutrik NJ3FC6-BAG, a professional locking 1/4 cable jack. For soldering I have Rotenberger ''silver'' solder 96%Sn+4%Ag. The original Pioneer cable was replaced with two meters of EPC-3 and Neutric plug. From the other 4 meters I've made an extension cable with the Neutric plug and jack. So I have around 6 meters line (a bit longer than the distance between my music and my sofa). Also I put some small amount of poliester batting (wool) in the ear cups, originaly they are empty. After 3 days of listening I will say that the result is better than before, now they sound more clear, dynamic and more transparent. Sorry but it's always was dificul for me to describe a music with words.
So what about the rating? For me they are amazing, they are my new/old Pioneers and I like how they sound, they are my discovery, my back to the golden ages of HI Fi, may be I should give 10(of 10). But I think it's dificult to compear the SE-205 with the contemporary models, it is a big difference (I've listened a modern Focals, Audio-Technica, Denons, AKGs, SENNHEISERs and others).
Honestly I'll give them 7(of 10).
