We've got one for you here. The five-star Sennheiser CX 400BT true wireless headphones are down to half-price for Amazon Prime Day. You can buy them now for just £79/$99 while stocks last.

Sennheiser make two true wireless headphones  – the CX 400BT and the more premium Momentums. Those looking for active noise-cancelling will need to shop for the latter but, if all you need is some great audio at a remarkably convenient price, then pull the trigger on these CX 400BTs and you won't regret it.

We originally reviewed the Sennheiser CX 400 BT headphones at £99/$100 but the price has since sky-rocketed to £169/$200 – until the Prime Day sales arrived.

Fantastic sound quality but without all the noise cancelling and other expensive frills – these true wireless buds are absurdly good value at this Prime Day price. Don't hang around or they'll get expensive again.

The combined battery life is 20 hours (seven hours from the buds, plus a further 13 hours from the charging case) and that should see you through several albums and feature films before you need to connect them for a USB-C fast charge.

They might not be waterproof like their bigger brothers but their lightweight fit makes them a great choice.

Sonically, they're clear and detailed with plenty of rhythmic energy. While we wouldn't recommend them as the best pair for runners, they're an excellent set of all-rounders at what is now a pretty unbeatable price. All yours for under a ton.
