If you want to hear a dt770, I could always send you one if you like. Isolation though isn't much better and if I'm honest, the msr7 is better. Given that isolation is much of a muchness between them, I prefer the msr7 sound tbh. Anyway, you're welcome to try the DT770 if you want to. Just pm me and I'll get a pair off to you. I would take Ian up on his kind offer Simon, I did many moons ago and he ended up giving me the DT770's which I still own toady I really like the DT770's - they have a good open sound for a closed back headphone and isolation is not bad at all, they are also very comfortable. I recently made a filter for my DT770's for use with my portable Kameleon and it does address the problem of the bass bleeding into the mids and also taking out the treble spike. Once filtered with the portable Kameleon they are a great headphone for me. I have never heard any headphone dearer than about £100 so I don't have much experience with headphones. On a personal level though I listen to my DT770 most of the time through my Samsung phone / Kameleon set up and occasionally my Philips Cityscape. I only use headphones for portable use. The DT770's are maybe a little large for portable headphones, but if like me you will only use them around the house, then they are very good. I will be surprised if you do not like the DT770 especially once filtered (thats if you have a portable Kameleon?) Take Ian up on his kind offer and let us know what you think you are right , it is a very kind offer (thanks Ian). i would like to hear them filtered too, though. i do wish all manufacturers would quote the passive attenuation value in dB of all closed phones, it would give me a chance to rule some out quickly

The amount of attenuation in closed headphones to me is pretty consistent Simon. They all work up to a point and most, enough to drown out noise once you have a moderate level of music going on. The only solution that does it (nearly) properly are NC headphones. They still don't knock out treble as well as bass. Closed headphones pick up external bass sounds sometimes a little too efficiently. The cups themselves kind of resonate tbh. I have a dt770 filter if you want to hear that as well. If you want a go with it, just say Simon. I may have other options here. I'll wait for Lucy to get back to school and Helena to work and have a look to test out closed headphones efficiency that I have here. They do vary, but frankly, it's not a lot. Way exaggerated I think by many. Best seal would probably be pleather or leather. Then varying tightness of the clamping forces. Velour does work as long as the stuffing is substantial. I would seriously consider the msr7 since it has a better quality of sound imo than the dt770. Don't know if you could get at one to try because not many places leave them out. I managed to hold on to my one for a little while longer until I get one myself. Thing is, do you want portable or semi portable for home use? Portable means small headphones and maybe a loss in sound quality where the dt770, being a big headphone with a cable that doesn't detach can be awkward to move around with. The msr7 does both with ease since the lead can be changed. Cheaper option and ok for sound .... kind of similar to dt770 is this ...... www.amazon.co.uk/Edifier-H850-H-850-Headphone/dp/B0083DPIIA/ref=sr_1_1?ie=UTF8&qid=1484504875&sr=8-1&keywords=H850+headphoneI used another version of this for pit work and monitoring the feedback from the band via the soundboard while conducting some shows ... the PJB. It's just a slightly higher spec than the Edifier but the same headphone, designed by a bass player in the business, Phil Jones. It has a big bass and treble with again, recessed mids, very similar to the dt770 but works mobile and is very comfy. I used to wear them for the whole length of a show while playing. Not as piercing in the treble as the DT770 so goes loud without too much hassle. I might have an Edifier around somewhere because I lost my PJB's once for a couple of weeks and so got an Edifier to replace it for a short while. Could send it with a dt770. If you want a go, just say. I have no problem sending them to you to try out.

i do wish all manufacturers would quote the passive attenuation value in dB of all closed phones, it would give me a chance to rule some out quickly Simon, the specs I have for the DT770, 80ohm are: SPL 96db Freq response 5 - 35Hz Noise isolation 18db Clamp pressure 3.5n
Hope this helps?

I've also never used Skype before although I'm no stranger to Facebook Messenger & Apple Facetime. My internet connection is only 13MB though so a conference call is probably beyond my capability. Thank your lucky stars. I average 15 to 16 Mbps Gordon so I guess everyone gets lucky twice. I tried FaceTime once. Had to go buy another iPad the next day. My new one has tape over the camera lens to avoid damage! These devices can only take so much punishment. Besides some might have trouble understanding my California accent. For those of you with a more fortunate face, the Skype idea sounds like something to look into.

Comparing the two on the head shows them to be pretty close.

[/quote] thanks mate, i had found the info on beyers but not on the AT's. Ian did mention the "M" variant, i wonder how they achieve the difference? are there small ports on the other models that are blocked on the M version, for eg? also , i wonder how the sound signature compares? now if i can find the attenuation value of the d2000 i will have some kind of idea how these would improve isolation. i may be able to get a try of the msr7 at currys this week. our local store is small and does not stock them, but i may be able to get to big store in reading at some point. (work permitting) thanks guys

The isolation on the 'm' version is down to a stronger clamp, Simon.
I have always found differences between closed headphones quite small in terms of isolation. They generally tighten the clamp to get better isolation which can be uncomfortable on the jaw after a while.

I had trouble with iems for a long time until I found a pair that actually fit me and then I had some customs made for my ie8. Then they went in very comfortably but were difficult to get out!!!
The Trinity Audio iems sound glorious and cut out a lot of noise. I'd say that they're actually dangerous to be walking around the street with because you'd be run down before you'd realised a car was even there. There are still fit issues with them though.
Go for a good sound. Even with half isolation, the music will push out noise at a reasonable volume.

I suspect with the DT770M the use of pleather pads rather than velour will also help the isolation. Coupled with a strong clamp to create a good seal of course. I had issues with IEMs for a while too but have become accustomed to them now. Some pairs are more problematic than others and ones that make contact with the cartilage in my outer ear are near unbearable. I suppose like shoes it's a case of finding a pair that is the right fit. Tips can help too and foamies are particularly good at adapting to the shape of the ear canal, which helps both in terms of comfort and blocking out external noise. ( oldson ) Don't know if you noticed my post re. the Trinity Vyrus a page or so back Simon (if you did just ignore this) but the offer's still there if you wanted to try a pair of IEMs again risk free. And if they didn't work out you could always pass them onto another member via the Freebies section

Sorry. I forgot about the pleather as well. You're right, plus the clamping force. It's actually quite strong - I did try one. A bit sweaty too.

decided against a bid on these. i remembered there was a driver issue with this model. these are not old and still within warranty but seller has no purchase invoice. not worth the risk, imo.
