Pretty much. Check it out
Honestly I just don't see the attraction to this over a regular combo cable. In fact I would see it as a downgrade as that volume control is passive and therefore is just a volume cut. The belt pack just seems unnecessary to me when you could use one of these cables. I guess I really don't think that belt pack would be worth the price increase when you could use something like one of the Rolls PM series units at the other end and come out the same, or less, money wise and also have even more functionality.
