Tone2 Pro ear pain

Audio
7

Hi

  • If you use 16ohm earphone,you should choose low gain mode.

  • It is best that do not use 4.4mm cable to test 3.5mm headphone,it may cause R cold pin and L cold pin short out.

Hi
What is the version of your update firmware?

9

It’s 1.41, I used tone2pro-xmos-v1.41-221201.bin

10

Actually I don’t think it’s related to the firmware. I started to feel uncomfortable again after using it.

11

Hi
Can you take a high resolution photo or video about how to play with tone2 pro? Thanks.

12

The aluminum box is the tone1, I have tried swapping it for the tone2 pro. It is connected to a headphone amp with rca cables. I also tried using a 6.35mm to 3.5mm adapter and using earphones with mmcx to 3.5mm and 4.4mm cables. Every case gives me ear pain. I think the tone2 pro is defective, I do not have this problem with the tone1.

Hi

  • Every cases you mentioned is OK.

  • I want to make sure with you If the ear pain you said is distortion or having a lot of noise,or any else.Can you descibe the details about your feeling?

  • Do you remember what is the firmware version of your inital tone2 pro?

I don’t think it’s distortion, everything sounded like it was supposed to. It feels like high frequency noise, but I can’t hear it. It’s a sharp pain in the ear when I use headphones. When I use earphones, it’s not immediately noticeable, but hurts after a few minutes. The other person I had try it said they felt dizzy and had a slight headache.
The firmware version should be v1.00. I updated for every firmware release and tested it, but something always felt off so I never used it.

Hi
I know it maybe related to the MCU firmware, do you update MCU firmware by ST-Link from the bottom of tone2 pro? As to the picture shown below.

If you not,you can try to do this as the video we released.

I have done the upgrade once before from V1.00 to V1.20. Should I try doing it again?

Hi
You can try to update the new MCU firmware by ST-Link.

Flashing the MCU firmware resolved the issue. I have been using it for ~40 minutes now without experiencing the pain. Thank you for your help.

@Eric68 I don’t think the problem actually went away. Flashing the firmware did reduce the intensity, but it still feels uncomfortable to use. I tried using it every once in a while to make sure, but it seems like the problem is still there.

Hi
Can you send us to check,please？

21

I can do that. How should I send it? Are there any instructions?

22

Actually, I looked at the cost of sending it back and it doesn’t seem like it would be worth the trouble, especially since it’s out of the warranty period.

Hi
Can you ask after-sales sevice for help？From your describe about the sound,it seems like the filter you choose is not fit you.

24

Oh,it may be related to the MCU data memory,you should try to write the default data to the data memory.

  1. You should write the data to the option byte by ST-LINK.The date you can download from here.
    You can have a try as the following picture.

I just tried updating the DFU with tone2pro-xmos-v1.41-221201.bin, then updating the mcu with tone2pro-mcu-boot-app-v1.4-221128.hex and the problem seems to be resolved again.
Is it necessary to update the mcu separately?

Hi
If the version of your Tone2 Pro is lower than V1.3, you should flash MCU to updata.othewise,you should not to flash MCU.
