  1. Went through the review of this newly launched yes, would love to try them but not unless they are launched in the Indian market.

  2. A great review. I bought this before reading this review. I see the author mentions aqua jogging and that’s one reason I bought this. But I found that with my iPhone XR which is also BT 5.0 capable, reception was spotty even within a 5 meter range. Having said that, I’m now also tempted to try the TE-D01d and see how that sounds like.

    • Thank you. 5 meters should be OK, unless there are a lot of interference, I have yet to test this on a iPhone XR so I cannot comment.
