Sennheiser's HD 25 is an iconic professional masterpiece. But don't just take my word for it: This is a headphone that is no stranger to DJs and sound engineers across the globe.

Not only as bulletproof as they come, but the HD 25 also offers a reliable, strong midbass response, pinpoint imaging, a wide soundstage and excellent isolation. It's standard-issue equipment for concert, studio and TV environments, and has been for over 30 years.

In June, and to celebrate the company's anniversary these classic workhorse headphones are discounted to £87 (down from £129!). And if you're lucky, you might receive a limited special edition version instead.

With only 25,000 Limited Edition versions available worldwide, this unique model comes with bright yellow earpads; a cheeky throwback to the world's first open headphones, the Sennheiser HD 414. If this doesn't tickle your fancy, they have included the standard black earpads as well.

The logo on the side of the earcup has also been given the retro treatment, as well as the packaging and sleeve, dressed up as if it were a retail package from the 1940s.

If you're after a new workhorse headphone that sounds great either in a mixing environment or at home, snag yourself a deal today. You might be lucky enough to receive a limited edition piece of history, sure to become a collector's item, while you're at it.
