I received my Bluetooth yesterday and started using it last night. Previously I purchased Boult audio pro bass. Now when it comes to plus and minus when compared to the other...there is a bit of range difference while attending a call. boult is a bit better than this when it comes to distance. but the sound quality is good in both. when it comes to noise cancellation Lumiford is a bit better than Boult. I am not finding any other disturbance sounds while speaking in a call. but ring volume is too low here when compared to Boult. Earbuds are very comfortable in-ear when compared to Boult. The music is decent but I expected more. The depth in music should have been a bit better but overall a decent one. But my final conclusion is to go for Boult audio pro bass which you get for 999 only.
