    • The 650s are my end game sound signature. Best Mid-Fi headphone, period.
Style: HD 650
What can I say about these headphones? These are the best cans for their price and honestly well above it. When you first put them on you're greeted by a heavy clamp. To fix this, I extended the metal piece to adjust the headband and bent them outwards. The metal is what can withstand this so don't bend the plastic headband, it'll snap! The thick velour still gives a bit on a grip as your ears will certainly be making contacting with it but because the cans are oval shaped it shouldn't be too bad. After you get over the clamp, you realize how smooth and forward the mids are. It was fun and great and all but it sounded so muffled. I was disappointed to begin with. From there, I ran some pink noise for only about 20 hours or so to burn them in. Did it change the sound significantly? No. But what it did help with is to bring out some detail and helped me get used to the sound faster. The biggest change you'll have to get used to coming from bright headphones is the clarity is not forward and sharp, but rather it's present but not the star of the show. You'll hear pretty much all the detail you'd care for but it's much quieter and subdued in the background. This leaves you with just the vocals, and boy do they sound silky smooth. You'll be able to easily hear every word and jarring treble or poorly mastered tracks will be greeted with forgiveness on these. Basically, all your music will sound good. Jazz sounds particularly good with these as do slow songs as they fit it's personality great. Pair these with a good amplifier, I recommend the Valhalla 2 for an entry level or a Ragnarok if you can afford it for solid state. Honestly, these could be your end game if you prefer the sound signature. For me, I still wasn't convinced as I knew the comfort could be improved and I wanted more detail. I ruined a good thing by doing so. The rings that hold the pads onto these cans are glued so I took some scissors and ripped them off. I replaced these cans with the HD700 pads just to try. The comfort instantly increased but the bass quantity went way down (while the quality of the bass picked up, it was much more speedy and less bloomy than with the stock pads), the detail and treble went way back up and to my surprise the mids recessed a tiny bit but not by much. This could probably be fixed with tubes. Doing this pad swap though took away everything that made the 650s magical to begin with. They really do change the sound so I recommend sticking with the stock velours or equivalent if you like the bassy/warm mid forward sound signature of the stock 650s. I certainly do so I will be buying them again (they are overpriced though, they basically are velour stitched over memory foam that you could take off some old packaging, $50 is a bit too much for pads but I guess they had to add up the costs to equal the total sum they're charging for this can). So who is the 650 for? If you can't afford $1,000 cans but want sweet vocals and impactful bass (not crazy deep but rich and heavy when necessary) then the 650s are definitely up your alley. It's super forgiving so lossy files will not be a problem here nor will poorly recorded music (which is a good thing in my books as it gives you time to build up your higher quality collection). I would not recommend these headphones if you want airyness, lots of detail or clarity. Those are best reserved for the 600s, 700s or 800s. Where's the upgrade from here? Pre-fazor LCD2 or LCD2-C or the Atticus. You'll need some beefy hybrid/SS amps for those but they are indeed a better upgrade as their soundstage, mids, and overall bass are better with a bit better clarity (not night and day). To wrap things up, the warm sound is not for analyzing your music. It's for relaxing as you go about your day, it's for enjoying lyrics, it's for sipping some coffee while writing up a paper. Details are fun but I finally have found my preferred sound signature. Bright sound signatures will fatigue your ears after a while with all the detail and glaring sharpness and as a result, I think a warm sound will fit most everyone's preferences unless you're in the camp that wants to hear every last detail in your music. I'm just glad I heard truly warm cans and not just cans outfitted with some warmth to truly get an idea of the experience you get and that is one of just fun, relaxing, shivers down your spine with well recorded music. These things will love tubes! Get some Mullards, Telefunken, Philips Milliwatts, or Gold Pin 6NPC's for some additional warmth and less of a dry sound. Pour that syrup! ... show more

    • Future classic. You can quote me on that. Incredible, and possibly the best.
Style: HD 650
These headphones are slightly colored. Most people prefer that, but if you're using them for studio monitors, you won't find better than the HD800's. Trust me. But for everyday use, these can't be beat for dynamic open headphones. Combine them with a full tube amp and I highly doubt you'll find a better "stuck on an island the rest of your life" headphones. UPDATE: After having owned these for over a year now, let me elaborate on my thoughts on these INCREDIBLE headphones. Value: This is tough. If you like open headphones, and love lower model Sennheisers, like the HD595, HD598, HD600, etc, then you'll surely LOVE these. I owned a pair of HD595's for several years before I accidentally broken them due to the stupid long cable. These sound very similar to those, only with a slightly darker top end, and much much much better bass. And, they're just better overall, in soundstage, speed, bass depth, bass extension, resolution, etc. Some people just don't like the open headphone sound. That's perfectly fine, and if that's the case, you probably won't like these. But if you've owned open headphones and like the open airy spacious natural sound... then you'll ADORE these. Comfort: 4.5 stars. They're Sennheisers. Pretty much all Sennheisers are extremely comfortable. They're light. The pads are usually comfortable soft velour. They usually have medium light to light clamping force. They have really large oval cups that fit the largest of ears. If comfort is high on your list, these might fit your bill. Value: 5 stars. These headphones bat outside their league. Outside their price range. I've seem MANY people go from these headphones to new headphones in the 4 digit range, then go back to these. LOTS OF TIMES. It's for a good reason. These headphones are going to be a future classic. You can quote me on that. If you've never owned "audiophile" quality headphones before, this price might seem high, but trust me, to upgrade from these, you usually have to buy Planar Magnetic headphones like the Audeze LCD-2, LCD-3, LCD-X headphones or similar. Those are all $1500+. If you've never had good quality headphones, these might not be your best first choice. Not because they don't sound good. These sound incredible. It's because these headphones are 300 ohms and require a pretty decent amp. They scale well with good hardware upstream, so a good DAC helps a lot too. (and source audio, you'll want 320 KB/s mp3's and FLAC if possible) Soundstage: 5 stars. Do these have the best soundstage ever? No. HD800's have that title. Why do I give it 5 stars then? Because these headphones have a better soundstage than 98% of the headphones out there. Resolution: 4.5 stars. Great, but not to the level of Planar/Ortho headphones. If you've never heard $1500+ ortho headphones, you won't even know what I'm talking about anyways. Treble: 4.5 stars. I'd give it 5 stars, but the treble on these headphones are rolled a tiny bit. You may hear them described as "dark" or "veiled". That's relative. To me, I prefer darker headphones anyways. Bright headphones are fatiguing and give me a headache after a few minutes. These roll the highs just enough to make them easy to listen to for hours, yet leave enough treble there to leave the top end nice and sharp. No sparkle. Sparkle bad. (depends on who you ask lol) Mids: 5 stars. Sennheisers' bread and butter. These have incredible mids. Through tube amps, or hybrid tube amps, the mids are lush. Liquidy. Warm. Female vocals will give you the chills. The warmth of the mids on these cans will make you smile in aural ecstacy. Bass: 4.5 stars. These headphones are probably the only headphones from Sennheiser with really good bass. The bass isn't as tight or deep as on Ortho headphones, but for open cans, it's incredibly impressive. I give the bottom end a tiny tiny bit of EQ to boost the bass, but other than that, it's the best bass I've heard from open headphones yet. The punch is pretty solid. I'd rate punch 3.5 stars. Bass extension is really good. I'd rate it 4 stars. Overall though, I give it 4.5 stars considering these are open headphones. Scalability: 5 stars. These cans scale like crazy. Upgrade your DAC: you'll heard the difference. Upgrade your amp: you'll hear a difference. Upgrade your tubes: you'll hear a difference. These headphones just keep giving. I used to own HD595's. They blew my mind. The bass on those sucked. Worse than Bose Tri-Ports, which were aweful themselves in bass. But you know what? I loved the lush mids so much, as well as the airy soundstage, I didn't care about the lack of bass. Those headphones broke later (my fault, not theirs), and I was forced to upgrade. These headphones are an improvement in every way. (other than weight and clamping force, the HD595 was lighter in weight and clamped lighter, but not by a whole lot) What's the best amp to drive these? EASY. Bottlehead Crack with Speedball upgrade. They're hands down the best amp for these headphones. Ask around. You'll get the same answer. Any full tube amp will do. Even the hybrids sound good, but for some reason, these headphones come alive with a full tube amp like the Crack. DAC? Any external DAC will suffice. The $99 one from Schiit is fine. Bifrost Uber even better if you can afford it. O2. Lots of choices. Just don't drive these from the on-board audio on your motherboard. That's just wrong. The best part about these headphones? The headphones two to three times its price are only a marginal 10-20% better, if that. And those usually require another 4 digits worth of gear to be worth getting. These headphones are at that bang for buck price point where you really start to get diminishing returns when you try to upgrade from these. Pros: Lots. Value. Soundstage. Lush mids. Soft highs for long listening session with no fatigue. Awesome bass, in headphones that have open airy sound. Removable cable. Scalability. Cons: ONLY con: You will have one HELL of a time finding headphones to upgrade to from these headphones. Be warned! These are so awesome for their price that you'll have a really hard time finding headphones you'll like better. That's not really a con though, but since I can't think of any cons, I'll list it as one anyways! If you've heard other open headphones and like the huge soundstage and open sound, and want to upgrade: GET THESE. Don't even hesitate. You'll be blown away. Just make sure you have good source files (320 mp3's or FLAC) and a full tube amp like the Bottlehead Crack amp. Thank me later! Enjoy! ... show more
