I love this product, but sadly, it has not worked as hoped with the TREO 650I have heard that it works great with Moto phonesHowever, I think that both the Moto 810 and Moto 850 have better volumes, and are both more comfortable and lighter, than this unitIf you must have Moto, then grab a Moto 810 or Moto 850If you want the best, grab a Cardo Scala 500 -- the best bluetooth device for your Treo 650
