Bought a pair after watching your video and man, do they sound good!

loved your video, I also subscribed because I like your reviews, so keep them up! :)

From this series in 2003 were HD525. A little later, I took HD580 from New York (but they didn’t linger - they had some kind of unpleasantly biting midrange). Somewhere in 2006-2008 there were two versions of the HD650. Modest treble, the middle is slightly synthetic, but the main problem is the dominant mid-bass, when the double bass sounded - it clogged all the lower mids. And then I got Beyerdynamic....

Great video!

Thank you! Man, this was warm and relatable to watch. I got my HD545s in 1998 (20 years ago) when I was 13 (yeah I was lucky) and I will always feel nothing but love and admiration for them. Being a kid and getting true audiophile level sound quality back then, was one of the best things during my next 10 years period of my life. Then I switched to newer Sennheiser’s, but each change would be either minor upgrade or somewhat different, or even worse (like hd700 which I still believe are Sennheiser’s fiasco) The interesting thing is that HD545 as far as I know were made in late 80s but they still can easily compete with today’s top audiophile line series by just being slightly behind, which is just mind blowing. They are very neutral and their sound signature is similar to HD600 but with wider soundstage equivalent to hd650. They are bit lower in resolution compared to 6 series or above, but then again, the sound signature is still one the best I’ve ever heard from the headphones, even to this day. I still have them, they still work, just needs all soft parts to be replaced, because they dissolved almost completely over the years. And even though I won’t use them as my primary headphones anymore, I will never sell them. It brings a smile on my face just by looking at them alone when I visit my home where I left them and listening to old cd’s through them brings me back to my warm childhood for a while. Have a good listening! These are from list of Sennheiser’s masterpieces.

Imo the late 80s/early90s HD 560 Ovation I and II are the best Vintage Sennheiser. The HD545 are great headphones too!

They are 150 ohm, not 300 ohm. Nice video mate, might have to pick up a pair as i'm collecting the whole 600 series.

I just Picked up a pair from a goodwill outlet store for less than a buck. sometime the right cable needs to be wiggled in headphone. I feel like I can wear these for hours where as my 380's give me the feeling that I need to pop my ears after 30 mins or so. I'm really digging the sound.

Thanks for sharing. Just picked up a 1985 HD540, sounds excellent.

If you have a chance do try out the hd540 reference 1 or reference 2, by far the best sennheiser ever made

Not to be insulting but really to just be informative and add to the discussion but the HD stands for Headphone and Dynamic. Thus why the Orpheus estats have the "HE" prefix. Oh, and I love the review.

Has someone have experience with actual headphones from sennheiser or other brand that have a similar sound to the amazing HD545 reference from sennheiser? Thanks in advance.

Hey, cool video. The HD 545's are awesome cans. One correction though, they are 150 ohm not 300.

Groovy. That house is indeed on fire! :) I've got 2 sets of these I purchased original in the 1990's... and of course the foam just evaporated from old age, even though they didn't get much use. I've got replacmement foam for the earpieces and headband on order from China. The cable plugs have been a pain since near the start - with my set dropping out one or the other from contact issues between the plugs and the contact springs inside. Whats the right solution? I'm up for your method of replacing the cable - but do they have 3.5mm plug versions? Who sells them?

hey man idk if will still read this but how did youchange the headband?

what is KA GG????

I personally think that the HD 545 and HD 565 sound better than the HD 580 Don't get me wrong the HD 580 are a good headphone but the HD 545 and 565 have a much better soundstage and clarity and much less clamp on your head feeling much comfier. This 5 series of headphone from the 90's in my opinion are the best Sennheiser produced.

How do you pull out the cables so easily? I can not pull them out and the phones seem to have no screws :(. I'm trying to replace the cable in order to fix the loose contact.

Money took over the sound quality, now you pay insane money for synthetic sound, guys! If you want THE best sound, seek for : beyer dt 48 older models (S, A, E versions in that order) pioneer monitor 10 (older model) If you are lucky, person doesnt know how good they are and you can get them for 20-80$ And dt48 is the most honest hp you can find, it will reveal just how bad your sistem is and it will make you spend money on good amp (thats a "downside" lol)
