Not so fast please
Before you send the UE back, give the Plantronics more time, get used to them, and compare the two side by side.
I had to send the Plantronics back before I could get the UE (which I have just sent back).
So I could not compare side by side, and I would like to read your impressions.
Mine are that the UE have fatter bass, deeper, with more body, better for things like Dubstep for example.
But the Plantronics have more detail, soundstage, a more refined and somehow delicate sound which have a subtle balance or warmth and freshness (while the UE are mostly warmer), and brighter wider airy highs.
The bass of the Plantronic I remember it clean, detailed, controlled, capable of good power when properly EQed, with good punch and some rumble, but not very fat and deep.
I loved the Bass of the UE, almost more than I love that of the Fidelio.
I would say that for bass of all what I testes is 1 UE 2 Fiedlio 3 Plantronics
The UE are anyway too heavy.
The Plantronics are not only Multipoint, they have also the Low latency Aptx codec (I am not aware of any other HiFi Headphones which support it). You still need a Low Latency Aptx transmitter anyway. And no Phone has it at the moment. But you can get it to your PC with the Avantree Saturn Pro or Priva.
The Plantronics, I havefound out lately, are Class 1 Bluetooth.
This is why their range is so good.
If there will be a Class 1 transmitter (which I did not find yet) they could reach such a range that you can go buying cigarettes on the corner with them on while streaming music from your pc.
Ok, maybe not so much, but, 300ft? that is 100mt, right?
