For a long time I've wanted some wireless headphones that are both encrypted and low latency, but I have never found any like that until recently when I noticed that Sennheiser now make some nice looking headphones using the "apt-X" Bluetooth codec, which claims to be low-latency. However, I can't find any good information on whether these headphones live up to this claim or not. Sennheiser themselves won't answer the question, and the headphones are too new to have any reviews yet. Nor can I find much information about real-world experience with apt-X at all.
I plan to use these for various things such as gaming, watching movies, and producing music, which all require low latency. I'm not super-sensitive to latency, but I suppose 10ms or less would be good. This seems achievable given the 3ms minimum I have seen quoted for apt-X (compared to the >200ms that I have been told normal Bluetooth is), but maybe that's a wildly optimistic best-case.
So, has anyone any experience with these new Sennheiser headphones, or any headphones that use apt-X?
