Pros: I love the sound and the comfort level of these earbuds. Decent bass response for in-ear headsets and crystal clear sound...when it works.
Cons: The connection is very intermittent. I go for a 45 min. walk each day and at least twice in that time the connection stops and I have to hit the stop/start button twice to get the audio back. It will also cut in and out as if the signal is being interfered with. I bought these so I didn't have to run a direct connection to my phone but the Bluetooth transmitting has been a real disappointment.
