48 headphones later, these are still in my top six – and they’re 38% off. The Sennheiser HD 650 stands out for its warm and detailed midrange, making it a favourite among audiophiles despite lacking sub-bass. While some may find the higher frequencies too pronounced, I’m not bothered by this at all.

Released in 2003, these headphones have endured scrutiny from tech reviewers but remain a modern classic for their natural sound and balanced profile. The HD 650 is open back and wired, meaning you can hear your music as it’s meant to be heard – just be wary of potential noise bleed.

The best price I’ve found is $358 at Amazon, down from its original retail price of $580. For audiophiles who value balanced sound over aggressive highs and lows, the HD 650 offers an unparalleled listening experience. Whether you’re a seasoned audio engineer or just someone looking for quality headphones, give these a try.
