What's your preferences for headphones with the Jolla?

I've been trying to find a suitable set of in ear/ear buds for the Jolla phone and it's costing me a small fortune.

I bought a pair of these last week for £50+

and all I can say is they are cr@p. At full volume (both phone and earphones) the music is just audible over the noise of a bus engine.

I have just ordered a pair of these and waiting for delivery:

Judging by the customer reviews they sound good.

I also have a pair of KS Manhattans which are both Bluetooth or wired and they sound excellent with the volume of the phone at only 40% they are louder than the Sonys at full volume, but although they're small they are still a little big to lug around on days out and shopping trips.
