Sony YY3004 Certified

Back in February 2025, I posted about a new unknown model, YY3004. This information came from a knowledgeable source, but what they provided was limited. The only information I received apart from the model code, were the colours, black, white, and blue.

When I first posted this information, the highest model code was YY2986 (WF-C710N), so I was skeptical. But now, we actually have a certification from Korea's RRA. The headset is made in Vietnam and is described as "Stereo Headphones".

The only headsets which offers these colours are the WH-CH720N and WH-CH520. Both of these were announced in February 2023, so it is possible are looking at a successor of either model.

 

Depending on the region, the WH-CH520 did have a 4th colour option, Beige, so perhaps YY3004 is the new WH-CH720N, or WH-CH730N, assuming Sony will use the same naming scheme.

The description does not mention noise cancellation, only stereo headphones, but previous RRA certifications usually used "Specific low-power wireless devices (wireless devices for wireless data communication systems)" as the description, so stereo headphones could be a generic term.

I do find it strange we are seeing YY3004 before YY2985 (WF-1000XM6), but I guess this is how Sony rolls. If anyone has any further details about this model, please contact me.
