I have and love these headphones. I own many and have been testing a number on writing. I am a big Sennheiser fan but did love the sound from the K712 from the first day. Over the last couple of weeks they have just kept getting better the more they burn in. Yes they are power hungry and no good on a mobile device. I got the IFI Zen Dac which they did sound great with but I was finding I needed to go past 12 oclock on the dial to or it was quiet on alot of tracks. So added the IFI Zen Can amp to the Dac (Connected with a 4.4 Balanced cable), and now wow they sound fantastic as they can be driven with ease now. I have tried them with Amazon Music HD and Tidal Premium (MQA) both were excellent. I highly recommend these headphones. Shame they don't have a balanced option too. Oh and amazing comfort they feel like my old Sennheiser Ovation 2's from many years ago and they cost much more at the time. And if anyone says there is no bass it's not true but you will need to use them a bit to get the best out of them, the range and soundstage is like nothing I have heard before, very impressive. I like Jazz, Classica, Dance, R&B and anything in between. So a wide range and these to justice to all genres. My M50X's sound so bad after I wear this for a bit. These are one of the best headphones I have owned ever and I have had many.
Thanks for your feedback and I am glad you like your AKG's and they are technically balanced as they use a mini xlr connector. About time AKG releases some more open backs.
they are amazing and I'm driving them with my tube amp set to high gain 300-600 ohm, set for my HD600 but K712 are just the same power hungry and results are very good better than my solid-state amp
I've got these, I don't have a dedicated headphone amp and I listen to them via the headphone output on my Cyrus One integrated amp. They're not my cup of tea. They're too analytical. I like a warmer sound I think I may sell them on. What would you suggest for a warmer sound in the £300-ish price range?
Yes I have the k712pro for almost 3 years, and yes you need a serious amp to drive this , to get the same volume as hd660s ( I own also) you need 30% mote power , a smartphone like my galaxy note8 barely moves them at full vol , I use topping mx3 at 70/100 volume to get them sound pretty loud, for hd660 I need only 55/100 to reach same volume
I have these(Austrian made: 011449) is this a new pair because I don't have the packaging that says '+3db' ? The pads are amazing but overall these things are built horribly. - they creaked when they were new - the leather headband is super stiff and does not conform to the shape of the head - the suspension system wears out very quickly and the pads slide down to rest the full weight of the headphone on the top of your ears I really have to find a way to replace these elastic wires from the suspension system The soundstage is amazing and my definite pick for any orchestral (soundtrack) recordings but I was very glad I picked this up for 100 EUR secondhand instead of around 300 new
I think the Austrian made ones are the very early ones. I have owned these for around 3 years and I got them used so not sure of the actual age. Mine have very little use so are like brand new but I will definitely take all of that into consideration. The soundstage and is great and I agree they are really good with orchestral recordings. I paid around £165 from memory. I would have liked to have seen these with the K812 adjustment system instead of what is on the rest of the lineup.
I only payed 125 quid for mine new from Amazon, they will be here Monday. I will tell you if the G6 will power them ,it's 16 ohm to 600 ohm of balanced sound!
@@VortexReviews1 I heard them several times but I want to try an open back design cuz I already have a closed back. I'm curious of open back cuz ppl says that it has better soundstage, so I can use them for gaming too.

You and a POWERFUL AMP just to listen to what is being said in this clip.

I am glad you like them. I sold on my K712's.
How do these compare to the legendary HD800s
No idea sorry. Not tried the HD800s.

I sold mine as well and as you did not mention open or closed back them maybe the Sennheiser HD58X or 650?
@@VortexReviews1 Thanks, probably closed so i can listen while the family watch TV
@@andrewcopley6454 Maybe the AKG K553 but I have not tried it.
@@VortexReviews1 I went for the Meze 99 Classic in the end Arriving tomorrow
@@andrewcopley6454 Nice one and let me know your impressions of it.
These are a really great set of headphones.
Indeed Akash.
Good set of headphones but yea, you need an amp to reach their full potential. What amp did you use?
I used my Mayflower Arc MK1 and O2/odac Rev B.

Will my Audio Interface Presonus Quantum 2626 drive these headphones?, The specs says Headphone Impedance (working range) 16Ω to 300Ω
Thanks.
I just had a look at the specs and on paper it will.

Nice price that G6 might be good enough.
@@VortexReviews1 There are quite a few sold from China atm which go for sub 100 USD at this point.. weird
@@bluex217 👍
I have these and I am looking to buy hifiman he400i 2020 version , you have a 4xx as well which one do you prefer?
I sold my 712 Pro and I do like the HE4XX but I want to try the Sundara one day.
@@VortexReviews1 Sundara is best headphone I have heard, but they were too heavy for me and caused neck pain.
@@JohnnyLongpube I heard about that but I may still try the Sundara but I will have to sell my HE4XX first.
Will the Soundblaster XG6 power these?
I have not tried that sorry and I sold these long ago now.
@@VortexReviews1 No probs. Thanks!
Does the mini XLR cable mean it’s a balanced headphone? I assumed that cables going to each ear cup meant it’s balanced.
I think so but I don't have a balanced amp to confirm this. The K712 Pro is power hungry and would appreciate the extra power from a balanced output.
Late to the party, but a single socket headphone can not be balanced without modification. Check out custom cans in the UK for this mod
do you have superlux headphones?
I don't but I heard they are good for the low price but need pad swaps.
@@VortexReviews1 Yeah, I'm planning to get them. I want to try a budget headphone after trying bunch of chi-fi IEM's.
@@linolingelbach2214 A solid headphone from China which does not need any mods are the Takstar Pro 82.

Best of luck Lino. I agree open back is better for gaming.
I had these for a bit and sold them on. Much prefer the Philips Fidelio X2s.
I own the X2 as well and like both but they are tuned a bit different and have different purposes.
Any amp around 100$ than can get the job done
There are a few that can do it like the JDS Atom, Monoprice SPark and Schiit Heresy.
@@VortexReviews1 witch one of thees are power them to 100%?
@@VortexReviews1 i was thinking to get Schiit Asgard 3 but people say it gets really hot but the sound will be really good for my akg 712pro
@@DeejayRach0 they will all power them to 100%. But which is the most powerful amp- it's the Schiit.
