Review: Stellar headphones - but only for certain genres - These are hands-down incredible headphones for non-bass heavy genres. They have a way of letting you hear things in music that you've just never heard before, and might just make you cry. It's truly an experience, and I adore them for it. They're comfortable (though a bit tight-fitting at first), well-made, the cord is good and long. They feel solid but they're not too heavy. The one downside is they do have a significant bass roll-off, meaning they don't perform as well for genres like rap. Everything sounds fine; they're just a bit too 'polite' for music that's meant to have a lot of punch or heavy bass, so if you're looking for that, look elsewhere. But for most other music; rock, pop, classical, some electronic, the experience is -phenomenal-. If you've never experienced a good pair of Senns, you're in for a treat. You will need a DAC/headphone amp to power them, as they are high-impedance headphones. I went with the Topping DX3 Pro+, which works just fine, though I had to use the high gain setting to get the full power out of these. Also, although they sound great out of the box, a little EQ will really let these shine - in Windows, Peace on top of EqualizerAPO will let you choose some great AutoEQ settings that you can then tune to your liking.
Review: Yes, get the 650! They’re the jack of all trades in the amazing HD 600 tier line of Sennheiser! - These are a part of “knights of the round table” headphones. Let me get something straight — there is no one perfect pair of headphones. It’s a curse to the wallet but yet it’s a blessing in the sense that headphones are a magical journey of taking two of your senses (hearing and touch) to whole new levels you may never experience by simply just by being in it. With so many headphones out there, there’s that many ways to explore audio and more! Exciting, right? I am an audiophile and have a room dedicated to my headphones as well as listening. Audio is an incredible passion of mine and I want to share my take on these 650s! 1: So, Sennheiser is among the crem-de-la-crem (pardon the spelling) of headphone producers. 2: Sennheiser is a great brand to get into headphones when you’re new to it. It’s also got great value for performance. You honestly can’t go wrong with them. 3: If you’re on a budget and can really only afford to just have that one or two pairs of headphones. The Sennheiser 650’s are a jack of all trades with its sound profile. They are a definite buy for sure! Paired with a Khadas Tone Board and JDS Labs Atom, you can have a pretty top tier, affordable setup. For real sides! 4: These work well with so many different types of DACS and amps. I personally pair them with THX789’s from Mass/Drop, Khadas Tone Board, or my Okto Research 8’s. The THX 788 made by Monoprice is a nice combo DAC/AMP. 5. In terms of the Sennheiser line, there’s the boss tier (not necessary at all to own) like 800 and 820s. There’s the studio recording line denoted by PRO. There’s the lower end with the 598 and below. The 600 range (where these headphones sit at) is the sweet spot of excellence. If you want a bass-y emphasized performance, go with the 58X from Drop.com. They’re the resurrected Jubilees which are an updated, updated version of the HD580s. These are super solid, great for listening for long periods. You can’t go wrong. You can plug these into a device without an amp and get great volume. If you want super duper separated sound with ridiculous detail with more revealing performance in the highs and mid/highs, the 600s are your go to headphones! They’re very objective (an audiophile term generally meaning “as-is” or “unemphasized” as possible). With the wrong setup, they can sometimes even be a little sibilant. The 650s are truly the Goldilocks of the HD600 line. These emphasize the mids much more than the others. It’s often considered a sin by some audiophiles to use EQ functionality to adjust the sound. I can say that the 650s are at that point where they can be lightly EQ-ed to offer more bass and treble response. Now, onto the last thing that I think is important to mention — these have been replaced and succeeded by the Sennheiser 660s. They’re a worthy successor to replace the 650s. They are pretty close in frequency response. However, the upgrade comes with the comfort (clamp force) and the consistency of the drivers to produce frequencies. What does that translate to? - The HD660s really do a good job of sounding good with vocals, slightly less warm, and sound good without a lot of readjustment on your ears. They’re on the brighter side than the HD650. The brightness is a personal preference kind of thing. For some, they might like this for classical music. For some, they may find themselves hitting user fatigue sooner than the 650. My opinion: The HD650 are still my go despite the update with the 660s. I think that the 660s is wonderful but I prefer to stick the HD650s because of their versatility. I can listen to them for hours! It’s a great starting spot for audiophile tier headphones that will always, always be my daily headphones for all kinds of music. They’re also a great starting spot as well as a great spot to end on. Additionally, I would check out the Sundara by Hifiman if you’re wanting to explore planars. They’re very much like the 650s of planar headphones. Enjoy and happy listening! :)

## Questions & Answers

**Q: Are they better than beats?**
A: For all the Beats haters out there, they're not the overworked, bass heavy, poorly made headphones the other snobby answers seem to make them out to be.

I own these Sennheiser 650 cans. I also own the Audio Technica 50 that many others seem to drop in the answers to this question.

Truly the answer is to each his own. To be fair, it's important to compare Beats and these while hard wired, ideally into a headphone amplifier. 

Once you listen to Beats hard wired like these or other high quality headphones, you'll quickly realize Beats are no dollar store wannabes.

Funny, but if you like listening to Dr. See or Snoop, you may like the Beats more, I know I do on occasion.

These are reference quality headphones that really aren't for everyone. They do not hit the bass very hard, the highs are not accentuated, and for those audiophiles reading this, the sound stage is wide open on this Sennheiser 650, while the Beats is tighter, more enclosed, tuned to rap or metal or electronic music.

You may find these lacking if you're used to headphones tuned for more emphasis as opposed to replicating audio as recorded in the studio.

These are amazing headphones no doubt, but you must have the right equipment, starting with a solid headphone amplifier. Beats simply need a Bluetooth connection. 

I hope this more balanced answer helps those trying to decide on their next headphones.

**Q: how do these compare to the hd 598's**
A: I just did a back-to-back test of these two headphones today (I own the 598's). The 650's sound better. They have an incredibly natural-sounding reproduction. It's.... perfect. The problem with the 598's is an over-emphasized mid-low area which in layman's terms would seem muddy. Also, the high's have a bit of sizzle, which is common among dynamic headphones, especially AKG's (also tested out their whole range today). The 598 holds it's own amongst other headphones in the 200-500 dollar range, but the HD 650 is in a class by itself.

**Q: Does it support/ us it on android phone?**
A: The 650-s have 300 ohm impedance. This  makes them not the best option for an Android or Iphone  handheld. 
For that application, you are better off with a lower impedance headset, e.g: the HD 585  is 150 ohms, the 280/300 series  is 62 ohms.   The 280-s are closed back, and excellent for listening using a mobile device.  The HD-650 will be rather quiet directly connected to an Android phone. 
The 650 maybe overkill listening to compressed content, as it is common on mobile devices.   The typical use scenario for these is connecting them to a high quality source (often, driven by a hi-resolution player, playing Flac or Dsd or some other high resolution material), using a headphone amp.   I own the MassDrop version (the HD6XX), and I also have an older HD-555, and the HD-555 is a better experience plugged into my LG android phone, streaming "high quality" spotify.

**Q: Can they be used effecively on an airplane?**
A: The 650's are not noise cancellation headphones and inferior to Bose, for instance, when using on a plane. In addition the 650's can be heard by others because of the open design. They are superior to everything else for solo listening when you are not on a plane.

### ⭐⭐⭐⭐⭐ Great, but make sure you pair this with a good DAC/source and AMP
*by J***4 on November 16, 2025*

If you're willing to invest in a good DAC and AMP combo to pair with these headphones, then they are highly worth it. I have mine paired with a Schiit Audio Bifrost 2/64 (DAC) and a Schiit Audio Midgard (AMP) with Mogami Gold Balanced cables between the DAC and AMP. Sounds great with acoustic/folk/rock/classical/orchestral/vocal/country music also performs well with most pop music. I would not recommend these for RAP. The clarity is great, but you'll probably find them a bit lacking in bass for Rap music.
