Shure SRH840A-EFS

I bought these as an entry level studio headphones. I was hoping for Shure's legendary SM58 type of quality and here's what my impression is.

The sound quality is perfect for my amateur purposes. I use it as a monitor set for playing bass guitar, midi instruments and vocals.

The comfort is great. Good padding on the right places, covers the entire ear and very lightweight construction.

The cable is long enough and is good quality as well. However the 6.35 jack adapter could be better. It's a screw-on sullution and therefore can't really be used on other 3.5mm jacks. Not a big deal but I like universal solutions.

What's my biggest concern about these headphones is the build quality. The body is made of cheap plastic. Only time will tell how long the pivoting joints will last. Unfortunatelly that's the most vulnerable point of all headphones and having broken three already I'm a bit dissapointed to see Shure's product this flimsy.

Overall, good headphones and definitely serves the purpose.

I have owned the previous generation model of the SRH-840 and love them and used them everyday for the last 4 years. I still have them but wanted to try the new model and see if they still match up sound and quality wise. So my review is mostly comparing them to the previous gen so bare that in mind.

NEGATIVES:
The overall feel of the headset is one of corner cutting compared with last gen, plastics feel and look cheaper and they dont look like they will last nearly as long as my old ones have. The earpieces rotate and the hinges seem flimsy and would probably break if they fell onto anything other that carpeted floor. The cable isnt as premium as the old coiled one but is serviceable I suppose. Comfort is not as good as the last gen not terrible but still feels more clampy on the head but maybe more time to wear in will help with that.

POSITIVES:
The sound is pretty much the same as the old gen which was my number one concern and thankfully they didnt cut any corners here from what I can tell. I did some testing with my guitar plugins and amps and some basic music playback and they seem to match up to my old gen ones pretty close. There maybe some subtle differences in the treble ranges but no massive noticeable differences. Thankfully they didnt cut corners here from what I can tell.

CONCLUSION:
If you are thinking of upgrading from the SRH-840's of the last gen and think you will be getting the same quality feel and durability I would say probably dont unless you can get them for a reasonable price i.e <€100.
They sound good so if thats your major concern then dont worry they will serve you well on that front, just dont expect the confort and durability to anywhere near the previous gen.

These are good headphones.

I had the previous version 840, I liked them. But I sold them because of their heavy weight.

The bass has become cleaner and deeper. There are ports that load the bank!
There is much less mumbling, or none at all.

A good middle ground.

There's more top end, but it's not "beyerdynamic").
These seem to be lighter colored headphones now.

I play the guitar in them, the guitar in them sounds dense, full-bodied and angry, like a real pumped-up tube amp. I like it!

In general, this is the sound of the 840, perhaps it differs in some way, but there is definitely no way to compare.

Headphones + part of the cord, weigh about 300 grams.

I really don't like the fact that the cans spin horizontally!!!
I bought a Thomann cable tie which fits perfectly, tightened it around the rotating hinges and now the cans rotate just a little to ensure a comfortable fit, but don't rotate)

The cord is of high quality and it’s good that it’s straight. But it is oak and has a microphonic effect, transmitting rustles, touches and blows well.
Theoretically, you can make your own cable.
Buy a twisted cable, cut it, solder a 3.5 mm plastic socket.

Other Shure ear pads fit here.
I tried 840 and 1540. But I decided that the original ear pads are much better quality and sound better.

The depth of the ear pads is the same 18-19 mm, but you can insert a wire or balcony insulation there, this will increase the internal depth and the speaker will not touch the ear, this will not affect the sound much, the stage and body of the sound will increase.

I especially like that on the manufacturer’s official website in the questions section it is written that the speakers are matched to each other in terms of sensitivity.

These are cool headphones! I think the Shure update was a success.
I've had a lot of headphones, now I have 770/80 and 990/80.
I will definitely keep 840A for myself.

I generally really like Shure's sound philosophy.

It's been a little over a year and a half since my purchase of these headphones.
I bought those for listening, and sound editing for video. I've used these for listening the majority of the time.

And the sound is GREAT. S(h)ure -:), it does have features typical for closed-back headphones (little boxed), but the precision and soundstage are very high. I got ZERO complaints about sound quality.

And, the build quality is not bad either. I've read some complaints here about it, having the plasticky feel and whatnot, but I just don't understand what all those people think they should get for this amount of money?!
- The plastic and sturdiness are FINE. After a year and a half of several hours a day usage, these headphones are still in excellent shape, like new ones. The cups, the leathery coverings, the cable, all have been holding well, with no wear-and-tear signs.
Except for one, stupid thing: the cloth that is covering the sponge under the headphones connecting bridge has come off.
Id did not tear off, or break from using, it just stopped being connected to the ridge on one side, suddenly. Probably because the connection to the ridge is not deep (a millimeter or two). It is unfortunate, and I can assume it happens occasionally, after all, this is serial production item, but it spoiled a bit overall excellent build quality review.
I removed the cloth completely (didn't wanna fiddle with gluing it, but it is doable)

Another thing, and this one I decided should not influence the comfort review, is the fact that these are too short for my very big head. Opened to the last notch, I still need a little more height to properly fit me, so I have to put them on an angle and press them a bit to fit my ears.
People with regular-sized heads or smaller, will not have this problem at all, and apart from being small for me, these are VERY COMFORTABLE headphones. The cushions are not too loose or too hard, they are put in appropriate places. Even with angled fitting, these still don't bother me while I wear my glasses. The pressure is not high, but enaugh to hold the headphones reliably on place.

Overall, I consider these to be really good, especially considering the price. The only reason I am thinking of switching now would be the size for my head.
But it is not easy to find that info or examples in practice, since I live in the part of the world that does not have stores in which I could test it.
