I bought a pair of B&W P13s at Xmas, and so far I am impressed. First 2 way active BT IEMs. £169

Build quality and materials are good. BT pairing is very good - better than most of the numerous BT devices I already have, and you can pair to multiple devices. All major BT protocols, including HD supported.
They are comfy to wear, neck band controls (vol, track, phone answer etc) simple and effective. Discreet to wear too.
Sound quality is very good for my tastes, very B&W in house sound - smoother end of spectrum, but great sound stage and still exciting.
I see they are on offer TODAY at hifonix for £118. That's a bargain -annoying I paid full price!!!

I also have PX7s over ears and Shure SE846s, and these compare vary favorably in terms of fun, SQ and VFM.
