Volume is correct and there is no breath is very good: the sound is reproduced faithfully, this is essential!
The connection is good (2RCA and an Aux jack), the cable may seem small for some; it does not matter as standard.
By cons I still have the same reproaches on all these 2 receptors: no on / off button and impossible to disable too powerful blue LED even if the size is reduced and the rather plain aesthetics.
