Sony YY3000 – How many earbuds does Sony need?

A new import filing has revealed another upcoming headset, YY3000. All 3 import listings are for Japan, and the headset is described as having a “charging box”, so a charging case.

The HS code points to headphones and earphones, so we cannot use that to identify what this is exactly. Edit, I have been comparing various older listings, and 85183020 seems to be earbuds, so these are either earbuds or an in-ear model. For example the IER-G900 (INZONE E9), when imported into Japan used the same HS code, 8518302.

So if this indeed is a set of earbuds, where will they be positioned? Sony already has the upcoming WF-1000XM6, WF-C710N, WF-C510, LinkBuds Fit and Open in their lineup, which is enough to cover the entire market segments. The WF-C510 is one model which could be replaced early next year, but that could be YY2999. Edit 2, while this could be a pair of earbuds, it could also be an in-ear model, not wireless.

Sony could add a pair of earbuds to the ULT line, so perhaps this is what we are looking at here. Honestly, I have no idea. Sony in a past interview said they wanted to simplify their lineup and remove models, so why add another one? Puzzling. Any ideas?

Update – March 11

There are more import listings, which show the same description, same country (Japan), but only dates from December 2025. Still have no idea what this is, or if it even is anything at all. HDX-3000 does not exist in any import filings just yet. Puzzling

Update – February 21

New import fillings for November 2025. These are not recent, but the import site does not update its database that frequently.
