Hello everyone, and congrats for the quality of the information shared here. I am no expert, just passionate about music and gear: I also love to save old stuff from trash bins and thrift stores and try to put them back in action, accepting all the limitations of age and technology. Headphones can be easy to fix, for sure it's a low-risk investment... Looking here I found many headphones that I know or own - Beyers DT990, both in 600 and 250 Ohm version; some Superlux, many Sennheiser, Hifiman HE-35x massdrop...
However I have not found any trace of famous pieces of the old days like AKG k141, 600 Ohm. Any reason? Also, no info about Sennheiser HD40, 600 Ohm: yes they were bottom-of-the-line back then, but were (and still are) considered very good for the price and the materials... I both have them (well AKG's have a broken driver, did not find a replacement).
I also own a pair of Superlux HD660 - the clone of Beyers DT770 - at 150 Ohm, they're not at all bad (well highs can show a good amount of sibilance, which Brainwavz pads did not attenuate).
Anyway, I am more curious about the k141 and HD40, if there's a reason to ignore them I'd be interested to know.
cheers from Italy Marco

The K141 are partly on-ear. Not everyone likes that. 600 Ohm versions also have a low sensitivity 100dB/V and require some amplification making them not suited for portable gear and low powered audio interfaces. it also has quite a lot of resonances and is outdated (small drivers). Not a bad sounding headphone but there are good alternatives. Of course for a collector or someone that likes retro stuff it is a fun headphone with a clear sound and lacking bass/warmth.
The HD40 is a cheap on-ear that lacks bass extension but does have good mids (what I can remember) and is very, very lightweight. Cannot find measurements for it. An interested owner would have to send one in.

An interested owner would have to send one in. Great feedback, thanks a lot. yes the k141 have a small driver, 30 mm I think. Dismantling the headphone wasn't the easiest process of them all to get to the broken one. I listened to another k141 of a friend and yes it is exactly this sound, no great bass but clear overall. He's a journalist and they used that model for years in studios. That's how I got mine for free, I'd like anyway to find the original driver just for the fun of restoring them. HD40 were my first serious headphones (the very first one being a Philips N6301... which had a clamping force like a vice). Never found again the yellow sponges for the HD40 though, only black. They still work. Anyway. I normally use the Beyer 990 at 600 Ohm and occasionally the Hifiman 35x mostly for rock and jazz, acoustic guitars, folk. very little classical music. Have a great weekend!
