It could be possible next year in Q3 but I doubt that it will be anytime before that. I doubt it would be in Q4 for the holidays, considering how Sony usually release their products.

Unfortunately, we haven't had any indications that they plan to release a XM5 wireless earbuds. They do tend to release their wireless earbuds with a two year gap between them, so 2023 does make sense. If I had to guess, the MSRP will be the same or slightly higher at $300 USD. The problem is the international chip shortage that has delayed a couple of products from other companies, that could be an issue if it gets worse.

I would be interested in the XM5 for sure, but we shouldn't be expecting it anytime soon.
