Are these HD6xx's worth their weight when not using a $$$$ reciver or tube amp? I just have a Sony STR-DH790. And I bought it 2 years ago. I don't really plan on upgrading it anytime soon. The HifiMan Sundara's are what the other headphones are called right? no model number? I think I'm going to buy those. I'm a semi-noob here.

I’m confused, they may be good and natural sounding, but why would they be better than superior headphones? Less fatigue or something?

Sold my HD600 so now I'm waiting for 6XX lol wont make that mistake again 😅 its like "hello friend your back" experience, we want them in collection for midrange magic + tubes magic

I started with HD600 i then bought some Sony, B&W, Focal,Hifiman,B&O,Koss, etch etch ... Guess what... I sold them all and buy an HD600 again . Now i only use HD660s ( they are my favorite just a smoothed HD600 with better imaging and tighter bass) and HD600 . I believe that people searching for an upgrade is a waste of time . 90% of the music is mid and highs and high bass , All of that are amazing on HD600 , and for those looking for sub bass then just EQ them they can do that easy , very capable driver .

@@Tripokaridos22 Well to be honest first that came close to HD600 was my Focal Clear with better highs and bass, still own them as they can scale very well with gear especially tubes. Now I also have Verite Closed and here I will compare midrange of 6XX with them as they are champions in that regard. Third and my most favourite is Audio Technica ADX5000, those are something else. Balanced and transparent sound, scaling with gear superb. At this case I give no chance to any Sennheiser (dont count that for 60k) sound is so clear and well defined that I could have only those :) ofc with my tubes they are heart of my headphones

they EQ fairly well, when you realy push them (+7DB) they don't sound as effortless as an LCD-X but they cost literally 1/3

invest in otl amp for 6xx

Amazon UK had the Sundaras for £150 recently. What a steal

I don't really like the R70X. Sounds grainy. Tonality of it is decent, I guess, but I agree that the Sundara is better.

@@Precogvision thank you so much for the response 😀

660’s just a darker 6XX from memory

I have all HD 5 HD6 series . and Sundara. From all HD6 series HD650 is the darker smoother, 600 the most neutral and 660s is in the Middle . All hd 6 series are warmer than Sundara. HD660s vs Sundara , Sundara more clear bigger sounstage but sound artificial and metalic some times , HD 660s warmee more natural better timbre , smaller soundstage and amazing imaging ( i would say a bit better than sundara but close) Both Sundara and 660s are amazing so its all about taste . Be aware i am on a third pair of Sundara the first had left driver problem and the second the membrane waa crackling... Hifiman has great support change them under warranty.

@@Precogvision 660s are not darker than 650. Some people report that on Headfi forums and thats because there was a banch of 6XX that sound brighter than normal also use different pads. Normally 660s are in the Middle brighter the 600 then 660 and darker the 650 , i also have 6xx and they sound a little bit brighter than 650 but not so much. Other than that technically 660s are way better with better imaging detail sepperation ... But keeping the warm character and smoothness of 6 line. Sundara are like i am listening something digital so clear and fast and 660s is like listening something so natural analogue . Honestly i love both and use them depending my mood. But if anyone doesnt like warm headphones then Lcd 2 , hd 6 line , Empyrian etch etch are not for them.

I think it’s difficult to say because of the pads. Worn pads have been shown to measure darker. The 660S I heard at Senn store was darker than the 650 haha.

​@@Tripokaridos22 yikes. what version sundara do you have? I bought mine at the start of 2021. so far no issues. thanks for the lengthy reply! I always appreciate long detailed insights! im curious how much of a downgrade the imaging is from the 660s to the 6xx? I'm considering going 6xx since it's the classic studio headphone that a lot of people that I follow use the 650 for mixing and referencing. (i just lean towards the 6xx since it's the cheaper version lol) but I'm quite scared too what if it's too dark or warm for my taste. I do appreciate some warmth as long as it doesn't smear details. 660s is the most expensive and most similar to the sundara but I guess ill have to save up for more if I want the cleanest presentation with the most detail and technicalities? or is the 6xx just a slightly less technical headphone with tastefully warm mids? but then how muddy can the 6xx get in busy heavier tracks on the low mids to bass area? I hear the 600 has great tuning but not much technicality wise but great timbre? honestly i'm just looking for a dynamic driver headphone that can compliment the sundara in technicality but adding that timbre that dynamics can provide with a neutral tuning. nothing too warm but with enough details that aren't overly smeared.

Any amp would work just fine unless it's a tube amp. Planars are usually picky about tubes from what I have heard.

the measurements I saw said for 102 db 5.7v and 250mw, so zen can/topping l30, that sort of range or better of course as apparently they scale well esp with voltage increase

@@snowmean1 or schitt magni 3+, forgot that popular one.

Sundara

How sure are you that it will only last 2 yrs??.. Unless you will use it outside while doing sports activity which is so awkward to do.. all of us use these type of headphone in our room, home, or studio.. Sundara will last just like any sennheiser.. it depends on how careless & clumsy the user then any headphones will only last as short as a month..

The headphones will last a decade.

Oh belive me they have super punchy bass.

@@Anomalyn1 This is not true. Simply bc in order to reach punchy bass the driver should extend to the sup-bass.

@@ammar5400 Agree, but just listen to them live. Then add some EQ and they are perfect. LE: they have sub-bass.

@@Anomalyn1 How they have sup-bass when they roll-off significantly in that region?

@@ammar5400 Somebody that has tried them said the bass has punch and you continue to argue. Try them like he asked and see for yourself.
