Sony YY3006 Certified by FCC

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.

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.

As always, if anyone has any details about this model, like photos, please contact me.
