Sony DR-4C vintage headphones.

post #1 of 22
Thread Starter 

I have just got a pair of Sony DR-4C vintage headphones off ebay. I will post photos when they arrive. In the meantime I cannot find anything about them on the internet. Has anyone got any knowledge of them?

From what i know they come from the 70's. Regarding the sound, they have enough treble and a reasonable bit of upper bass...thats all i know.

Thats a start winma, thanks. The seller knows little about them, except to say they do sound too quiet with a portable music device, so I see from the Sony site in 1979 they introduced the MDR-3 compact and easy to drive headphone to go with the first Walkman. So these probably pre-date the Walkman.

I guess they will need enough power to be driven, anyways i hope you enjoy your cans and post back your impressions!

They arrived. After a good clean, they are in very good condition and work. The fit is tight and supraural, but the thick vinyl pads make them comfortable. The band is solid and a bit uncomfortable. They are also for people with bigger heads, I only just fit them and I do not have a small head. The cable is about 2 m long and has a nice woven sheathing. 

 

Sound wise, they are managing to sound both bright and dull with the metal I am listening to at the moment. I don't believe in burn in, I do believe that your ears take time to adjust to a new sound. So initial impressions are not great, but not disasterous either. 

 

They need a lot of power to be driven to any reasonable volume. My X-CAN is at 12 o'clock minimum to work them, where as most other cans start at 9 o'clock. Best of all is that they do not leak any sound. Even at high volume you need to be sitting right next to someone and really listen when all else is quiet to hear the very faint noise they do leak. They are the most leakless cans I have ever experienced. Noise attenuation is also very good, i cannot hear a thing going on around me.

Nice cans! they look solid built. Most of the 70's headphones i've seen require a good source of power...

Congrats!

Thanks, they are very well made indeed. On the side it says input 10 K ohms and 1 mW. So 10,000 ohms, does that make them the hardest to drive headphones ever?!

Yeah, i guess you will need an amp. Do you have one already right?

Yes, the MF X-CANV8P, so lots of power there. It comes with a 1/4" jack, so I would need an adapter to see what it sounds like with the ipod.

After a day I have found that they are bright and forward with no deep bass and a treble that sometimes renders cymbals as one constant faint noise. However, the midrange, so long you like forward is super and they excel with jazz. They are keepers for me and I plan to add another 30 years to them.

Cool...Do they perform classical music good?

I don't think they would be great with classical as the construction makes for a small soundstage. Everything is channeled straight into your ear. Orchestral would suffer, individual pieces would do better.

I found this Japanese website which has a review of the DR 4M, which  looks identical to the DR 4C. The translation was provided by Google..

It would appear that the big difference is with overall sensitivity, with the DR 4C being very insensitive.

There are a good few hours on them now and they are capable of coming alive with respectable bass, but only at higher volumes. I have been listening to Devin Townsend and his wall of metal sound. The detail and clarity in the midrange are good and as I said before quite forward and bright. The kick drum is coming through, but with no great force.

 

They are comfortable and best of all, even with metal at full blast, they do not leak any sound.
