The add-on: OnePlus Buds 4

In the relentlessly churning sea of true wireless earbuds, it takes something special to make a splash. And these here are very special.

Let's get this out of the way: for the money, the OnePlus Buds 4 sound remarkably grownup. They're powered by a clever coaxial dual-driver system - basically, a big 11mm woofer for the rumbly bits and a separate 6mm tweeter for the sparkly bits.

Spinning up A.R. Rahman's Dil Se Re, the complex layers and thumping bassline are delivered with a tightness and control that feels like it's coming from much pricier picks. For the best results, stick to the 'Balanced' EQ preset.
