They did it! Sennheiser HD 480 Pro are the best closed-back headphones I’ve heard (and it's not even close)

I first fell in love with audiophile headphones because they offered so much more clarity, technical performance, resolution, and other words that basically mean perceived detail.

The pair that first opened my eyes was the Sennheiser HD 550, and they blew me away because their neutral/bright sound profile encouraged me to focus on higher frequency detail that I otherwise wouldn’t have noticed. The HD 550 also offers an excellent midrange with natural timbre, but it was the exciting treble that I fixated on.

The $400 Sennheiser HD 480 Pro isn’t here to excite you. Made for studio pros, specifically for tracking and mixing, the 480 Pro isn’t made for audiophiles, so instead of throwing fireworks at you, it paints a neutral, balanced, correct-sounding sound profile.

The result is the best closed-back pair of headphones that I’ve yet heard, and my new go-to recommendation if you’re looking for a set of the best-sounding headphones on sale today.

Sound profile

Overall, Bass and treble are gloriously well balanced without overshadowing the midrange. That’s a feat for any type of headphone – including the more forgiving open or Bluetooth sets – let alone a closed-back pair. The overall sound is correct-sounding with a touch of warmth. Nothing is out of place, and listening to music I’ve been familiar with for several decades, it all just sounds as it should.

The only negative aspects to the 480 Pro are preference-based, as opposed to glaring tuning errors. For example, you might prefer a different approach to treble than the 480 Pro – yet the 480 Pro’s treble is the best version of its approach that I’ve heard. All together, this is an exceptional-sounding headphone, and the best closed-back I’ve ever used.

Bass: This bass is full with plenty of detail and slam, putting a focus on sub bass yet still offering plenty of mid-bass punch. I find this presentation detailed, with some nice ‘grip’ to it. If I’m nit-picking, I can totally see it being too much bass for audiophiles searching perfect neutral, yet what’s on offer here doesn’t step on the toes of the midrange. It does, however, lend a warmth to things that some might not like (it’s definitely my jam).

You can get bigger bass in the far less expensive $160 FiiO FT1. However, you don’t hear bass in a vacuum, and where the FT1’s midrange’s clarity is hit by the wads of (wonderfully executed) low range, the 480 Pro’s overall balance remains faultless.

Playing Parliament’s Give Up The Funk, I love the fullness of the mid bass of Bootsy Collins in the intro. It has body and slam, backed up with a substantial sub bass that grounds the whole thing. On lesser sets that simply ramp up the bass, lower frequency details get lost easily, and listening to familiar music becomes frustrating – you can't hear the detail you know is there. That’s not the case with the 480 Pro. I get quality and quantity, and let there be no doubt, there’s plenty of quantity here!

Midrange: There’s more focus on the mid and upper mids, and less on the lower mids here. That makes the bass and lower mids seem more distinct, which is a presentation some people will love, and some will feel lacks cohesion. For me, the 480 Pro has the best of both worlds here, with the mid-bass being distinct enough from the mids so it hits hard, but not so much that the lower mids sound lean.

The ear gain region – the bane of many a headphone tuner – is exceptionally well done. I hear a little dip just before an elevation around 2.45kHz then again at 2.9-3.5kHz, followed by a noticeable dip around 4kHz. The former elevations are never too much, and serve as extra seasoning on male and female vocals.

4kHz is actually an area which usually gives me issues, so I tend to headphones that make a plateau around 2-4kHz instead of putting a spotlight on that area. The HD 480 Pro isn’t shy in this region, but it still doesn’t come across as shouty or grating. Instead, everything in the midrange comes across as timbrally correct. That’s basically the hardest thing to do with audio – any chump can make headphones sound ‘exciting’. The HD 480 Pro makes instruments and vocals sound correct, all balanced with each other. And when you put on a beautifully-produced track, the results are ‘right’.

Treble: To my ears, there’s a generally relaxed approach to the lower treble that I initially read as dark. However, the more I listened to the 480 Pro the more I found Sennheiser’s approach to the treble was purposeful and in accordance with the balanced approach of the bass and mids.

I get a little spice around 6.6-7kHz, a dip around 8kHz, and then a little bit more around 9kHz. But as with the ear gain region, these slight peaks give added dimension to the sound, rather than sounding piercing or sibilant. In fact, this is the smoothest detailed treble I’ve heard, whether open- or closed-back. Michael Jackson’s remarkably bright Billie Jean has all its stabbing peaks rounded off, and Lucinda Williams’ jarringly sibilant Sweet Old World blends in rather than stands out. That never happens!

Of course, as I've said, a subtle, smooth, balanced treble isn’t everyone’s idea of audiophile-grade audio (Grado still sell headphones, after all). I happen to love the HiFiMan HE1000, with its comparably elevated treble profile. I love that it, along with its incredibly open ear cups, gives me a sense of crisp detail – it’s what I think of when I think ‘audiophile’. And yet, the HE1000 isn’t a practical set for everyday use. It’s a specialised headphone for specific moments. With its balanced sound, the Sennheiser is both an every-day set for YouTube doom scrolling and a specialised set for critical listening. It’s a rare bird in that it excels in every area, so that it may appear unexceptional. That's far from the case.

Price, value, alternatives

At $399/£339, the Sennheiser HD 480 Pro is in a competitive price bracket. It's also in a tricky spot for budget-conscious creatives who may look to the cheaper workhorse classic the Beyerdynamic DT 770 Pro ($200).

The value proposition here, however, is undeniable and convincing. Where the Pro DT 770 Pro offers bucket-loads of perceived detail with its incredibly elevated, sibilant treble, the 480 Pro offers unparalleled neutrality that can be enjoyed for hours on end without fatigue.

Closed-backs notoriously struggle with boomy bass, due to internal acoustic reflections and resonant standing waves trapped inside the sealed ear cup. But Sennheiser tames low-end clutter without muddying the mix. This is really very rare. Factor in the featherlight 272g build and washable components, and it’s a brilliant, durable investment. For me, at $400, this represents excellent value. After all, it's one of the best headphones I've heard, and it will last many, many years.

HD 480 Pro vs Focal Azurys

The HD 480 Pro slams just as much as the notorious Focal Azurys in the bass, but it's cleaner and clearer, without reverting to the overly-bright approach of the Focal set.

The Azurys is a very comfortable, cool-looking pair of headphones, but it offers more of a V-shape sound profile than the perfectly-balanced HD 480.

The upside of that is that the Azurys is a more exciting, dynamic pair of headphones. More bass and more treble mean more contrast. The midrange is really good with the Azurys as well. Yet it's not the star, as it's slightly overshadowed by all the excitement. You get none of these compromises with the HD 480 Pro.

For me, the smoothness of treble in the HD 480 allows everything to pull focus, whereas the comparatively sharper Azurys can sound almost hollow in comparison. And I think this is largely down to treble, as both cans sound very similar in the midrange (and certainly graph so).

The Focal Azurys retail for $599, though you can currently (and frequently) get them for more like $449 over at Amazon, and though I'd recommend them to certain people, I'd recommend the HD 480 Pro to everyone.

HD 480 Pro vs FiiO FT1

I have a soft spot for the FiiO FT1 – and not just because they are one of the best value pair of closed-back headphones in existence, at $165 over at Amazon. They sound fantastic, with their vaguely absurd levels of bass, which is plenty detailed and only messes with the lower mids a bit (coping much?!)

But A/B testing the FT1 with the HD 480 Pro, I still think it holds up... kind of. Sure it offers a more dynamic V-shape sound profile to the Sennheiser cans, but just like the Azurys, it does exciting well. The bass is definitely the boss here, but the midrange isn't just bullied around as is the case with so many bass cannons.

However, when comparing the treble responses, it's like comparing a scalpel to a sledgehammer. The HD 480 Pro walks a fine line between detail and sibilance. Going between the two with the glitchy, treble showcase that is K-Lone's slk, and where the FT1 ramps up the highs, shouting the detail to you, the 480 Pro seems to convey all the same high frequency detail, but with more body. I know that might sound weird, to refer to treble having body, but the 480 Pro just offers a fuller picture.

DAC/Amp requirements

The Sennheiser HD 480 PRO is relatively easy to drive despite its 130 Ω impedance, because its sensitivity is reasonably high at 107 dB SPL (1 Vrms) or 98 dB SPL (1 mW).

What that means in practise is an M-chipped MacBook or modern PC will drive the HD 480 PRO effortlessly with ample headroom.

For music listening, a $9 Apple dongle will give you all the clean power you actually need. The only real limitation would be maximum volume if you're working with quiet, uncompressed studio recordings. Which I don't!

Bottom line: for the majority of music fans thinking about buying the HD 480 Pro, as long as you have a $9 Apple dongle, you're golden.

Build & comfort

Build and comfort are big wins for the Sennheiser HD 480 Pro. Although it may look like a lot of other headphones, this set really is amongst the most comfortable out there.

It's the combination of light plastic, stainless spring steel, and soft velour ear cups that make this a durable, lightweight headphone that doesn't register even after hours of use. And with that steel, you know this headphone is going to retain its shape, no matter how it's treated.

This level of comfort is rare on a single headband headphone (ie, not headphones with dedicated comfort straps to distribute the weight on your head). I've previously had to add an additional Capra strap to make most single-band headphones bearable – such as the FiiO FT1, or the HEDD D1. And all these super light materials are replaceable – the detachable headband padding is even washable!

The width and depth of the ear cups is such that my average-sized ears never touch the driver housing, and the depth and soft materials of the cups means that the passive isolation is excellent. This is actually one of the highlights for me, as I work in a home office with my beautiful (noisy!) wife and a an equally beautifully noisy gaming PC. With the 480 Pro, I get to immerse myself in great sound, and not be distracted by either.

This is a well-designed headphone that's not built for show, but is built to last a very long time. For $400, this should be the standard – if I'm going to spend $400 on headphones, I want to be listening to them in 20 years time. And there's no reason that won't be the case with the HD 480 Pro.

Should you buy it?

I've given this pair of headphones a full five stars, so the answer is obviously, 'yes, yes, yes – of course you should buy it'. But that doesn't mean they're for everyone.

So, who is this headphone not for? I think any audiophile who wants a detail monster set that offers high-treble sizzle excitement and accompanying hearing loss, should give the 480 Pro a miss. Instead, pick up a HiFiMan instead (my current favourite is the HiFiMan HE1000 Stealth).

The Sennheiser 480 Pro doesn't get in the way of the music. It presents it honestly and clearly. It lacks the fireworks of the more exciting sets out there, but this is a pair of headphones that you can use all day every day with absolutely no issues – in sound or comfort.

If you want timbral accuracy, supreme comfort, and the passive isolation benefits of a closed-back, there is currently no better option than the Sennheiser 480 Pro.
