If you mean that you think you would get the successor to the SE846 (whatever that might be), I didn't mean to suggest that they won't have the SE846 lying around and send you the newer version. You could still end up with an SE846. If it isn't bad enough that you really need to get it fixed now then maybe you wait and see what comes out (and save some money) but I wouldn't send them in expecting a low cost or free upgrade. I also sent my Senn MTWs (v1) back to Sennheiser last year for a broken case after the MTW2 came out and they sent me back a brand new v1. I wasn't expecting the MTW2 and was quite happy with the fact that they replaced my broken set free of charge. Whether or not there was a newer version out was not part of my decision to send them in. I only mentioned my SE530 --> SE535 upgrade because I was impressed that Shure offered me that (my SE530s were well out of warranty). If you need a repair, I wouldn't hesitate to send it in Shure. If it is out of warranty, I would just expect to pay the flat fee and shipping to them and they will most likely just send you a new earbud. Note, the cost is per earbud so if it's both sides you want to replace, you are probably better off waiting for sales.
