I received my Noble BTS several days ago and love it! I can't comment on pairing it with my K10U, as can't do that at the moment. However, here are some bonus PROs about this device:
o Wireless capability to ANY 3.5mm wired headphone, at least from the phone or portable device that has BT.
o Phone mic capability to any headphone (although you do need to put mic close to mouth for best results)
o BT connection allows most Android phone users to have remote volume control!
o I can listen wirelessly on better sounding Cowon Z2 for music, but have my phone connection take over when a call comes in.
o Small and lightweight
o Compared to LG atpx BT headset, the sound quality is much better, if nothing else, simply because I can choose a much better headphone!
Here are some points to note:
o Sound quality still depends on audio source. There is a big difference between sound, when using same headphone for both devices, between my LG phone and Cowon Z2.
o BT connection is still a bit lesser quality than wired connection, but with right source and headphone/IEM, it can sound really good!
o It does come with a nice short cable to use in K10 or other IEM with standard 2 prong in order to reduce cable.
o Wireless range is about normal as any other BT device. Quality and range depends on both the BTS and phone/device. Older BT standards will be a little less than newer ones.
o Notification light is tiny. You will have to learn all the functions, but will eventually get used to it like anything else. Don't forget to put your phones in first in order to hear voice give connection status.
Best Bonus of All:
I have the Bose QC 20 Active Noise Cancelling headphones for when I need peace and quiet (even more so than mere isolation) and the Noble BTS pairs VERY nicely with these! It seems to inject a little more life to the stale highs. Soundstage projects out more in a V shape, but sounds more open. Bass seems a tad punchier (definitely not neutral). I have never ever experienced chills from the sound of ANC phones. Never! Yet, a couple of times, I DID with this combination and Cowon Z2. Amazing! Most of all, it adds wireless from phone and as an Android user, I have volume control! Only bad is, now I've got two danglies from my neck...
Can't wait to try when my replacement K10u arrives!
