Sony YY3006 Certified by FCC

24 April 2026 TheWalkmanBlog 0 Comments

The Sony YY3006 has been certified by the FCC. The headset appeared late last day but it was rather too late to many a post.

I first discovered the headset last year in late August in import filings, so Sony has been working on this since the middle of last year, perhaps even earlier. The IMDA certification already revealed the model would feature noise cancellation, but it always good to get a second confirmation, especially if it is from the FCC filing.

The short term confidentiality end date is October 20, 2026. This is 20 days after the end date for YY3005, so perhaps both could be revealed together.

While I still believe YY3006 is the WH-CH720N replacement, it could also be a replacement for the ULT Wear. Logically the WH-CH720N should be replaced first, as it has been on the market for more than 3 years, where as the ULT Wear just passed the 2 year mark around 2 weeks ago.

The filling information is limit, but does reveal the battery capacity, 500mAh 3.85V, along with the 3 different suppliers, Highpower, Springpower, and VDL.

The WH-CH720N uses a 520mAh 3.85V battery. I do not think the 20mAh difference will be noticeable, especially if the new model is using more energy efficient components.

The company performing the wireless testing used a program called “Airoha.Tool.Kit”, which suggests the headset will be using an Airoha Bluetooth chip. Sony opted for the V1 (MT2822) in the WH-CH720N, so it is possible Sony will re-use the same chip or maybe go for an Airoha variant, like AB1585? Unless Sony just opts for the V2 (MT2833). Once I get the chip details, I will update the post.

The antenna document has a photo of the main PCB, it does not reveal anything specific, but it does show at least 2 ribbon cable connectors and a possible battery connection.

Perhaps one ribbon cable connection will be for the secondary PCB with the USB-C and 3.5mm ports, and the second connection for the cable coming from the opposite side.

There is a second photo in the antenna document, but it is of rather poor quality, so impossible to tell if the headset in the photo is the device being tested, or just placed their for setup/photo purposes. The photo is labelled as “test setup photo”, so deduce from what that what you will, but I cannot say for certain this is YY3006 in the photo. So if you see articles stating this is the new actual headset, then I did not write that, they did.

Sony YY3006 Certified by FCC — Sony YY3006 or something else?

That is all from the FCC filing. The headset was certified in on IMDA Singapore a while back (~April 17), so the FCC filing is not the first certification.

Here is the UL Solution certification from the previous day.

All subsequent certifications will go in this post, and any import filings will go in the original post from last year. Although if anything significant is revealed by the import filings, I will add the details here as well.

If YY3006 is the WH-CH720N successor, then here are a few things I would like to see improved in the new model:

Improved hinge design and quality
Folding hinge design
Improved noise cancellation performance
- additional ANC microphones, 1 feedback and 2-3 feedfoward
Transition all microphones to MEMS type
LDAC support
LC3 support
Overall better plastic quality for the entire headset

For any WH-CH720N owners, what would you want to see improved/fixed on the new model? Leave your comments below.

Update 9 – August 13

The headset has passed through India’s Bureau of Standards. The Indian certification also confirms the manufacturer as Tonly, which also made the WH-CH720N. A reminder, that the headset has been confirmed as WH-CH730N.

Update 8 – July 15

An older TDRA certification from early May 2026. I could not access the TDRA website, so I could not grab the cert.

Update 7 – June 14

The headset has been certified in Mexico. Nothing new is revealed, but with more and more certifications, we are getting closer to a release.

Update 6 – June 11

The Indonesian certification suggested that the headset would be manufactured in 2 different countries. I was not sure if this information was accurate, but thanks to a new South Korean certification, it looks like the headset will be made in 2 different countries.

In my May 27th update, I posted I have never seen any Sony headset with 2 production sites. I was wrong. In fact, the current WH-CH720N has 2 production sites, China and Vietnam. This is evident from the FCC filing, see the update on the post. My own WH-CH720N is made in China, but perhaps some units were made in Vietnam?

Checking the old South Korean cert for WH-CH720N, it only lists China as the production site, rather than both Vietnam and China. Anyone have a made in Vietnam WH-CH720N?

Tonly is the manufacturer for the WH-CH720N, and they have plants in both China and Vietnam, so I suspect Tonly again will be making the headset for Sony.

Throwing in a recent import filing as well. These seems to be parts for the production of the headset. I would think the headset is already in production, or starting production soon.

Update 5 – June 2

The headset was certified in Panama. Nothing new is revealed.

The headset is stilling showing up in import filings with the same description, for the past couple of months.

WIRELESS BLUETOOTH HEADPHONES (INCLUDING HEADSETS THE HEADSET MUST AND CHARGING BOX), BRAND: SONY, MODEL YY3006

But otherwise, no new import filings revealing anything new.

Update 4 – May 27

We have a certification from Indonesia. The certification shows both China and Vietnam as place of manufacture. ~~I have not seen anything like this for a Sony headset before~~. See update 6. One idea could be that the international variant will vary in some sort versus the Chinese variant, but then why not just make one model which can cover both markets? Strange.
