Well that is interesting - I just got my first email update for a subscribed thread since the update just now and was able to follow the link successfully from my phone. So I will now (perhaps unjustifiably) speculate that most members stopped getting email notifications of activity in their...

I think it's because people can't access the site from their mobile devices - I get a 'This site can't be reached' message when I try to browse from my Android phone.

Now is one of those rare times - they're $500.00 on Amazon Canada right now: https://www.amazon.ca/Sennheiser-HD-650-Headphones/dp/B00018MSNI Compared to the prices people in Canada want for their used 650's, it's an enticing offer(typically $450.00).

I have had the HP50's for 2 years now in daily use for 4-6 hours in various enviroments, including my car and at work, and they have not been treated very gently. I must say I find your contention that you find the build quality 'average' contradicted by my experiences - they have gone from...

In a report from CES 2016,, Tyll Hertsens (Innerfidelity) shows a picture from the NAD booth with him standing in front a big sign with a quote from his original review - "My favorite sealed headphone...". Tyll comments " It still remains as true today as the day I wrote it—it's easily the most...

You mean, 'nicer' like they were to these guys?:http://www.audiostream.com/content/abx-tests-prove-hi-res-audio-legit#c9aA3D4km2BG8IyS.97

If I wasn't sold on these before, this picture would have done it (but I was anyway, after seeing the THD+Noise and square wave graphs on Innerfidlity: http://www.innerfidelity.com/images/AudioQuestNightHawk2015.pdf

You know, I haven't seen the tell-tale lower-case 'b' on a single one of the dozen or so players I've seen

Can't help you with pad question, but I noticed in your signature that you're looking for something with decent isolation - well I can tell you that the HP50's certainly do isolation very well. I use mine to listen to classical music while I'm in the car - and without the lowered noise-floor...

Insanity, indeed - but at least we are able to self-treat with large doses of high-quality audio! On the NFL watching front, I see that players are wearing headphones on the field during preliminary warm-ups,too. There don't seem to be many IEM fans in the NFL, however.

Apologies in advance for going a little OT, but it's Sunday morning and I'm watching pro-football players walking into the stadium - and 4 out of 5  players are sporting full-size headphones - wish my phone-recognition skills were more developed. It makes me wonder if the unifying thread that...

Although they look a little square, I think that the criticism of the HP50's looks is overdone - the sight of someone wearing any headphone in public draws a certain amount of attention. Mind you, even here in a small town in southern Ontario, the sight of someone wearing headphones while...

Looking at the frequency response curve, you can see that the Nighthawk has what looks like a 7 or 8 dB drop from 300 hz to 1000 hz - but that is really almost the only defect I see in the AQ's page of measurements - the THD+N measurements in particular below 400 hz are probably the best Tyll...

My, aren't we be being a little bit arch?

My experience with the earpads has been different - after 16 months of daily use and with them being left in a car for hours a day at ambient temperatures varying between 0 Degrees F and 100 F, the earpads on my HP50's are in perfect physical shape - however I still would like to know where to...

Fair enough, but I can't help but notice you don't have any gear listed in your signature or on your profile page.

Would you share some particulars about the cable, please, Dr. Frankenstein - i.e. - source/configuration ?

You guys with the balanced raving again - going to force me to upgrade, dammit. Mind you, you've got me pondering a conversion of my NAD HP50's to balanced - it's dual entry so if I make my own cable and cut the feed between the earcups I could join the club fairly cheaply.

In my experience, even with input silent the E12 will still only last regular life(or a little bit longer). Recharging after 50% depletion has no negative effect on the FiiO battery(IMHO).

While we're on the topic of desired firmware fixes, I wish that they would make the 10 second lock option actually happen in 10 seconds, instead of the 6 seconds approx. I have measured.

'Banned' ? More like unburdened if you ask me - anyway thanks for the great pic! By the way maybe this will make you feel better   http://www.audiostream.com/content/abx-tests-prove-hi-res-audio-legit#iIDZ557EtGQgqfPt.97
