    • Come Down the Rabbit Hole (So Worth It)
Style: HD 650
These are the first step. Like anyone looking to make this kind of investment for headphones I did a lot of reading before buying. That is only going to get you so far. You need to hear these. Ten years ago I listened to a pair of HD600 straight off a disc-man with NO amp. I was completely blown away, I set out to find the perfect headphones for one hundred dollars, that was a mistake. I kept buying headphones in that range over the years and nothing came close. I was torn between these and the 600's, but decided that I loved the look of these and a few reviews pushed me to get the 650's. I highly suggest going to Guitar Center or some place that you can compare them, I believe the 600's maybe the superior sounding ones (it's always the ugly ones). It's been said that a good set up is the Lehmann Audio Black Cube Linear amp/HD600 using a 650 headphone cable. But there is no way I'm paying that kind of money for an amp... I'm not an expert and I don't plan to collect anymore headphones (unless I end up with a pile of extra money). If you are just getting into quality sound, these will destroy what you thought was possible for home listening. Even without burn-in, and an expensive amp and listening to a 128kbps file in itunes, you will want to throw out your old headphones, you will look at them with disgust and you will start ripping everything you own at lossless. These only get better with everything you bring to them, they are hungry for better. More than likely I'll be getting a Schiit amp as my first amp. Currently running these from an Apogee One for digtial or a Technics SA-5170 for vinyl and happy with this setup. I'd love to understand why people think these should have a dedicated amp. Things that you will notice when you listen. The sound stage will be expanded, the clarity and richness will be improved, the separation: you will hear things you never noticed (one voice will clearly become 3 layered voices, one piano will become 4, fingers will slide on strings) everything will become a personal concert. If you are on the fence about these don't hesitate, it's like going from and old TV to a HUGE HD one with bluray. If you are an audio pro, you probably already own these. If you didn't like something about these and you think they need to be amped, you have more money than brains (or very good hearing). If you want to significantly improve your daily enjoyment of music, buy these now. Like everyone else says there are cons: The band is tight, they are open so you can hear everything in the room (ie keyboard clicks and talking) and people can hear the headphones. These are most likely for home use only. Good thing they look more comfortable than most of the furniture in my house. You should know by now what you are getting into with these. These come in a huge foam lined box, there was nothing to cut, no way to tell if it had ever been opened or not. The cord is kevlar (think bulletproof vests) and replaceable, one time I sucked them into the vacuum roller (not this pair), seemed bad but survived (HD 495). They are light and comfortable to wear for me (not as comfy as my HD 428). They look amazing, much better than the HD600's. I think there is a lot that could be improved about how they are built (comfort and usability), but I'm insane when it comes to small details. You will want a multi-disc player or good quality digital music (big hard drive). What I listened to so far: NIN, Tool, The Cinematic Orchestra, Sam Prekop, Zoe Keating, Underworld, Aphex Twin, Miles Davis, Amadeus Soundtrack, Kodo, Led Zeppelin, Billy McLaughlin, Doomtree, Yo-Yo Ma, Alice in Chains (unplugged), Rodrigo Y Gabriela, Nirvana and Jimi. And I'll go to bed after I listen to everything that exists... These shine with live and acoustic tracks. Don't wait 10 years like I did. Get them now and start hearing your music for the first time. So worth it. On a side note, I'd consider getting a second pair of these rather than spending the money for a nice surround sound system. I figure the audio is as good but much cheaper. If Schiit is reading consider making an amp for movie buffs and their girlfriends to share. Update: I'd suggest the wireless HDR 120 for TV and Movies. Update: I recently found the Monolith Liquid Platinum amp for a great price as an open box almost half price from their own site. I also found XLR cables to swap for the headphones and for my CD player to the amp. I am extremely happy with this upgrade and was skeptical that it would make any difference but I am glad I invested. No regrets. A friend had recommended the Monolith Liquid Spark (probably a good option if you aren’t changing out the cables or have a lower budget), but once I found the deal on the Platinum I was determined to get that as my end game amp. I admit I should have made the investment sooner but it took me a few years too save up the money. Don’t waste these headphones maximize their potential with an amp. ... show more

All my life I hate headphones, because I couldn't listen to them longer period of times in ear canal ones were piercing my brain over on ear ones were uncomfortable with side effects my ears were sweating itching. Experience made me refuse buy any headphones over the decade because I've always felt they not worth it. Other hands I have quite old vintage Pioneer Hi-Fi Speakers which is my uncle bought in 80's. They still sounds great but only goes to frequency response 28 KHZ max. I have approximately 105 SACD ripped them to DSD ( Sony DSF) format with my old PS3, sacd ripper, Also Around 203 Hi-Res albums ( 24 BIT) which my friends & I bought shared through different online stores like ( Hdtracks, Qobuz, Hiresaudio.com etc). Rest of my collection just Redbook 16 bit 44.1 khz lossless format ), I haven't decent DSD native decoding DAC I'm using Macbook Pro 15. ( 2016) this device Audio capabilities garbage it has Cirrus Logic DAC muddy which only goes 96 khz, line out from this device only limited 48 khz max feeding this device through line out to amp to speakers were awful experience everything sounds muddy instruments sound separation, soundstage nothing is presents Hi-Res Audio sounded worth than CD etc. I have before Sony SACD player it laser head malfunctioned after 8 years of Use & went bad 8 years ago. After this thing broken from different laptops even expensive Apple Macbook Pro audio experience was worst I've experienced so far. I knew I need some sort of USB Audio Advanced DAC something to convert my DSD files Natively & Hi-Res Audio max out of resolution doesn't make sense have 24 bit 192 khz lossless file when your device DAC only can reproduce 96 khz can only output 48 khz max so you got my point. I have proper DAC now which Capable Play DSD ( 64,128) natively PCM up to 384 khz & line out headphone out not limited to 48 khz anymore it is alo headphone amp which have specs 285 mv ( 32 Ohm) 2.9 volt. 1. Sennheiser HD 650 Comfort ----------- I would give 10/10 never used anything like this before, you can listen for longer periods without getting any fatigue or discomfort they also very well breathable, I'm using this about 5-6 hours without break I've never got tired this is so big advantage this headphones have over others & what make them so special best in their class ( Note they have little clamping force in beginning when they are new but this thing easily resolved after 4 days of Use I left them on position Clamping Box 10 cm distance from each drives 4 days all day & this clamping pressure has gone) 2. Sennheiser HD 650 Sound Quality & Resolution ----------- Second batch of this product which is currently Amazon.com selling have frequency response up to 10 - 41.000 hz ( Hi - Res Audio Certified By Japan Audio Society) it has sticker on box, Sound quality resolution everything crystal clear bass in there ( Mids Vocals I've never heard anything like this they are magical & very straight forward & intimidate this headphones only woth buying just for listening female vocals they sounds so precious nothing come close this kind of quality this cans providing in this regard), Highs many others would say veiled actually I'm not agree with that they very well represented they just not piercing this is one of the magic formula which makes listen to this headphones long listen sessions without getting tired. 3. Sennheiser HD 650 -Power Requirement DAC, Amplification, Source ------------- This headphones rated 300 ohm, Power requirement for this I'm not 100 % sure but checked online headfi.org other online 3 volt 500 mv - 32 ohm, everyone says they incredible scales with powerful amp. I'm currently using them with my 2.9 volt 285 mv on 30 ohm source they driving this in required level so they sounds incredible, I've not t feeding them all 500 mv by now I don't own so powerful headphone amp yet. I bet with powerful amp they even getting better. Of Course Source material DAC also matters it will help get better results in the end. Currently my source 1200 ( 16 bit 44.1 khz albums lossless format), 105 DSD SACDS, 203 Hi-Res 24 Bit ( 44.1 khz up to 192 khz files) 150 albums I have in ITunes format 256 kb/s ACC, In my listening best sounding is DSD, 2nd place 192 khz PCM, 3 rd place Redbook CD 16/44.1, worst sounding AAC 256 kb/s . During listening sessions I'm more often trying avoid this ACC albums. So source matters as well to get full more detailed refined experience. 4. Sennheiser HD 650 - value build quality --------------- This headphones lightweight for it own class so you couldn't expect this thing being build from any metal it have metal where durability matter Driver Grills made from metal headband clamping sides made from metal, rest of the Unit it is high quality plastic. If you take a good care about your equipment I didn't think it will be broken anytime soon some people using HD 600 now over 15 years & nothing got broken during this time except pads & cable this is normal. This thing Made In Europe Ireland how many items do you own last 2 decades made in Europe ? Trust me build quality it is top notch. For 374.99 $ this headphones is steal. This is 500 $ valued headphones for the resolution comfort this thing provide I don't think they overpriced, nowadays any sub par Sony or Other HI-RES headphones costing 250 $ forget about bluetooth other futures every other headphone have sound quality through wireless option worst indeed, still best option connection for optimal sound quality is wire. Audio Software Used for testing Audio Nirvana Plus full version only available by this moment only ON MAC OS costing 74.99 $, It is bitperfect software have Lots of Audio futures & excellent sound quality 10 times better what average ITUNES sounds like, Native DSD playback, advanced metadata editing etc. I'm usually not to keen write reviews about products but I then saw some people giving this item sub par scoring one star rating so I decide wrote one. Please don't listen to this people they don't using this headphone as intended. They generally bought it plugged into smartphone jack or laptop, in my experience this headphone I'm not tried my smartphone but from Macbook Pro 15 ( 2016) headphone jack they sound like some cheap 15 $ no name headphone. So Please note ( Source, DAC, proper amp, all this matters to get full out of this headphones) ... show more
