Sennheiser headphones are now up to 55% off for Black Friday – sell-out risk high(!)

This superb step-up model in the Accentum range offers fast-charging, angled drivers for superior timing and detail, sound personalization to improve sound further, and aptX higher-res Bluetooth support to make the most of that sound tech. This isn't the absolute rock-bottom cheapest we've ever seen this model (that would be $129.95, ever so briefly), but it makes a model we already praised a lot in our Sennheiser Accentum Plus review even better value.

A great saving on Sennheiser's excellent over-ear noise-cancelling headphones makes this one of our standout deals of the Black Friday sales so far. They treat you to a beautifully detailed and crisp sonic performance and benefit from some strong noise cancelling tech. Plus, with a huge 60 hours of battery life, you'll rarely need to reach for the charger. And the deal applies to all colorways – even the Special Edition set with gold-tone accents! The regular finishes have dropped a little lower than this before now, but keep checking – anything approaching $199 will mean clicking to 'buy now' never felt so good. Just see our Sennheiser Momentum 4 Wireless review if you need further proof.

These true wireless earbuds are ludicrously comfortable to wear for long periods, thanks to their ergonomic and bijou shape. They sound good, too, as you'd expect from a brand of Sennheiser's calibre, delivering an engaging, spacious presentation. We have to admit they're a tough sell at their original price, only because of fierce competition. But thanks to this Amazon Black Friday deal, however, they just dropped to under $100 (a return to their lowest seen price, according to our dedicated price trackers), which makes them a no-brainer recommendation. If you've been considering them for a while, I'd strongly suggest buying now to avoid disappointment… 

I adore my own set of IE 600 (and the wider TechRadar team has written odes to their pairs), so I really want you to know about this saving. For clarity, it's an excellent deal too: the cheapest they've ever been on Amazon is $499 to date, so if you want to check to see if they fall this low again, Black Friday weekend is probably the time – at this very link. They're fashioned from a metal called ZR01 amorphous zirconium. Sounds premium, right? That's because it is – it's the same metal used for the drilling head of NASA's Mars Rover. And the sound? Oh, don't get me started (but do go to our Sennheiser IE 600 review if you need to know more).

Sennheiser's non-Plus Accentum model delivers active noise cancellation and 50 hours of battery life at a stunningly low price. With the well-balanced sound and strong detail of Sennheiser, these are a great deal if you consider yourself a music purist but you don't have an audiophile budget. They're comfortable and lightweight, too. Oh, and this sub-$100 deal is just $10 off their lowest-seen price ever, which means if they drop just $10 more at this link, that's a lowest-seen saving. Even so, this is a stone-cold bargain on a trusted name in audio.

A new all-time lowest-seen price on Sennheiser's excellent over-ear noise-cancelling headphones? Yes please! Although Amazon lists their most-recent price tag, I've listed the RRP just so you know the level we're dealing with here – and that it's easily one of standout deals of the Black Friday sales. They treat you to a brilliantly detailed and crisp sonic performance and benefit from some of the best noise cancelling tech you can get for the price. Plus, with a huge 60 hours of battery life, you'll rarely need to reach for the charger. And the deal applies to the black or white finishes – although not the graphite option. It's one penny cheaper than they've ever been and honestly, they're a solid bargain at this price.

A stone-cold bargain on a trusted name in audio.

I adore my own set of IE 600 (and the wider TechRadar team has written odes to their pairs), so even though the deal is available only on Sennheiser's website at the time of writing, I'm listing it here because I want you to have at the saving. For clarity, it's an excellent deal, if you're prepared to start another online shopping cart: the cheapest they've ever been on Amazon is £449 to date.

We have to admit they're a tough sell at their original price, only because of fierce competition. But thanks to this Amazon Black Friday deal, however, they're well under £100, which makes them a no-brainer recommendation. Clarity on the deal? Of course: they've briefly been £1 cheaper, but that's as little as makes no difference when Black Friday is heating up. If you've been considering them for a while, I'd strongly suggest buying now to avoid disappointment… 

This superb step-up model in the Accentum range adds fast-charging, angled drivers for superior timing and detail, sound personalization to improve sound further, and aptX higher-res Bluetooth support to make the most of that sound tech. This isn't the absolute rock-bottom cheapest we've ever seen this model (that would be £119.99, ever so briefly and a while ago), but it makes a model we already praised a lot in our Sennheiser Accentum Plus review even better value.

With an extreme frequency range of 8Hz to 41,500Hz and 42mm high-performance transducers, the HD660 S2 are capable of confident sound that doesn't duck any part of the mix from sub to treble. And with this huge £150 discount, you can get their pro-level sound for much less. And yes, for clarity, this is the lowest we've ever seen them sell for – and as our glowing Sennheiser HD660 S2 review explains, these headphones have the expansive soundstage you'd expect from a pair of open-backed cans plus supreme comfort, meaning they're a joy for home listening. 

This is simply a great discount to see on the brilliant HD 550 headphones. Supremely comfortable, with brilliant Sennheiser audio quality, these really could be a gaming headset killer for you as long as you don't mind being tethered. They're capable of uncovering extreme levels of detail. A new record-low price in the UK means the value has never been greater, and there's a host of links below to the discounted US price, too.
