One of the best DACs for using high-end headphones on PS5 is 20% off this Black Friday

I did loads of research before buying the Fosi K7 to use with my PS5 and PC, and I've not been this happy with a tech purchase in a while. Not only does the K7 make my gaming sound incredible, easily powering my open-back headphones, but it has also made music so much more enjoyable to listen to. I would pay way more than the RRP for this excellent product, so grabbing a bargain with a 20% discount seems like a total no-brainer.

In the UK, you can save 21% on the Fosi K7, and at under £150, I don't think you'll find a better DAC on the market. I kid you not, I cried the first time I heard Radiohead with my headphones plugged into this DAC, it was a magical experience, and one that's unbeatable for this price.

Thanks to their aluminum voice coil with 300-ohm impedance and open-back design, the HD660 S2 are capable of an expansive soundstage and a wonderfully distortion-free sound. While this $49.01 reduction isn't quite as hefty as their discount in the UK, they're worth keeping an eye on as they're frequently available for less.

If you’ve had your eye on the Sennheiser HD 560 S open-back audiophile headphones, now’s a smart time to pull the trigger. They’ve just dropped to a solid deal price that gives you premium reference-level sound at far below the typical cost. If you’ve been waiting for a high-end upgrade that won’t utterly wreck your budget, this is it.

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.
