Maybe someone will help, bandaged with a fabric collar, now they do not irritate))
I put a cable in the ear pads, now there is enough space for the ears.
It is strange that the manufacturer regretted 5 mm of depth.
With part of the cord Weight 315-320 grams.
The sound got brighter.
In general, this is Shure. But now I don’t have old 840s, I compare from memory.
4 holes appeared in the cans, probably to strengthen the bass and unload the can from mumbling.
Headphones are good, fit well, sound good. The sound is slightly harsh, requires an equalizer, but assertive, the whole range, it's definitely shur.
The question remains open, how does the sound of 840a differ from 440a?
And where can I get such a 2.5mm jack to make my own cable?
Native very oak, but high quality.
I wonder if the ear pads from 940/1540 fit here in terms of sound?
(Older 840s fit.)
