GRADO SR325E

£258, gradolabs.com

The SR325e are among the leakiest open-backed headphones we’ve tried – they’re not much good with other people around, or for travelling. But in a quiet room, they sound as good as headphones that cost five times more. Their sound is natural but not flat, expansive but still focused, powerful but never overwhelming… the amount of detail they enable tracks to deliver is eye-opening. They may not be for everyone, but we’ve never heard this level of audio opulence at this kind of brilliant price.
