To it’s factory settings :

Please try the following, in order, with the speaker plugged in and the battery in place:

Here is the latest firmware V4.60 for AIWA EXOS-9. Here is the link and it fixes the following issues.

iPhone and Google Pixel compliance issues. 1. When I try to play YouTube or FB video the sound does not play through the AIWA EXOS-9.
2. If I’m listening to music on YouTube, FB or Apple Music if I want to skip a song or go to a different playlist. The songs stop playing on the AIWA EXOS-9. I manually have to disconnect and reconnect to get sound back.
With 2 AIWA EXOS-9 connected, in TWS mode: you can set 1 speaker in L and the other in R mode for true Stereo experience. However when you disconnect the BT, it will fall back to default 2X  independent  speaker each with their own stereo mode. In TWS mode, the you can set the stereo mode (one unit set as “L” and the other set as “R”).   The default setting for the TWS mode is two units set as “L+R” respectively.   New firmware V4.60 memorize the users’ settings.   When the users set two units at stereo mode, it won’t go back to the default setting until the units are powered off.
L & R icon are gone and the link button on the master speaker doesn’t work in the last test version (V40R59).

Firmware 4.60

  • You need a windows PC. Mac doesn’t work.
  • Download the file from this link and unzip the files.
  • Once downloaded, connect the speaker to the PC using a usb to micro usb cord ( just like many phone chargers)
  • Turn the speaker on and double click on the file updater.exe
  • A black box will pop up and eventually show 100%.
  • Turn the speaker off and back on.
  • The BlueTooth name will be changed to AIWA EXOS-9 4.60 so you need to find and re-connect.


Qualcomm AptX Low Latency is still a relatively rare codec and support for it is far from universal.  After launching the ARC-1 we found that the aptX LL implementation on the headphone has issues recognizing many aptX LL transmitters on the market.

We have prepared a fix for this, but unfortunately the Qconnect feature can’t co-exist with this fix.  So, if you choose to update to this firmware, Qconnect will stop working. Please be sure before updating.

Download the update here.

How to install:

  1. Download and unzip the file.  Make sure you can find the folder where you extract the contents of the zip file.
  2. Connect your ARC-1headphones to your Windows PC via USB (unfortunately OSX and Linux support is not possible at this time).
  3. On the headphone, hold the power, volume up, and Bluetooth pairing buttons simultaneously.  After about 10 seconds a single red LED will turn on.
  4. Navigate to the folder ‘Step 1’ and run ‘update.bat’.  Windows may show an error about an unknown publisher or unsafe file because this file is not common.  You can ignore this – press “more info” or “advanced” and continue.
  5. When prompted, press “y” and hit return. Wait for the update to complete.
  6. The headphone will start blinking rapidly and saying “power on”.  This is OK.  As in step 3, hold the buttons until the red LED turns on.
  7. Navigate to the folder ‘Step 2’ and run update.bat.  Repeat the instructions from Step 4.
  8. The update should complete. Unplug the headphone from your PC and power it on as normal.  That’s it!  You should now have fully repaired aptX compatibility.
