Instructions on how to get your Aftershokz Trex headset to work with Bluetooth Multipoint

Posted on November 9, 2017

About a year ago, I wrote how useful the Apple watch was for me, but one problem still was unless I used my mess of cables hack I couldn’t get VoiceOver from both my iPhone and watch simultaneously.
The Aftershokz headphone company released their Trekz-Titanium model in early 2016 and many people in the blind community were excited because they claimed the titaniums had Bluetooth Multipoint. They did, but after 1-2 hours of trying to get it working I gave up in frustration.

Then the Apple AirPods came out and I was hoping they could do the trick, but no, the user has to switch between devices; they won’t do it automatically.
Then my friend Hai Nguyen Ly who introduced me to bone conduction headphones 4+ years ago said in passing last month, that he’d gotten them working in Multipoint with both his iPhone and Apple watch, so I decided to reexamine the challenge, and this time was successful within about 30 minutes.

Here are the steps to do it, this works for both the Aftershokz Trex Titanium, and Trekz-air models; hopefully they make sense.

1. first you have to reset the headset, Turn off the headset before beginning to reset it.

2. Enter pairing mode by turning on the headset and holding the volume up button for 5-7 seconds.
You will hear the Audrey Says™ voice say “Welcome to Trex Titanium, and then shortly after, “pairing”. The LED will flash red and blue.
Audrey will say Trex-air if you have that model instead.

3. Then press and hold all 3 buttons on the headset for 3-5 seconds. You will hear a low pitched double beep, or feel vibrations.

4. Turn the headset back off.

5. Enter pairing mode again by pressing and holding the volume up-power on button. Audrey will first say “Welcome to Trex Titanium” and then “pairing.” The LED will flash red and blue.

6. Continue to press-hold the volume up button while then simultaneously also pressing and holding the triangular multi-function button on the left. after about 3 more seconds Audrey will say Multipoint enabled.

7. In your first device’s Bluetooth settings, select your Trekz model. Audrey will say “Connected.”

8. Turn the headset off.

9. Reenter pairing mode again by pressing and holding the volume up-power on button. Audrey will first say “Welcome to Trex Titanium” and then “pairing.” The LED will flash red and blue.
10. In your second device’s Bluetooth settings, select your Trekz model. Audrey will say “Connected” or “Device 2 Connected.”
11. Turn the headset off.

The next time you turn your Trex headset on it will connect to both devices. It works pretty well, though here are some things I’ve noticed.

If I move out of range of one of the connected devices and then move back into range, the device doesn’t always reconnect. Turning the headset off and back on reconnects both again.

I said Multipoint lets you connect 2 devices simultaneously but that doesn’t mean you can hear audio from both simultaneously. only one at a time. This means if I’m playing a podcast on my iPhone, I won’t hear anything from my Apple watch; that has already bit me a few times. if I pause the podcast on the phone, audio from the watch will start playing in about 2 seconds.
Beyond that, using Multipoint is still quite useful. I can use either device in a meeting, concert, or at church. I can also use either device while traveling in loud situations like around heavy traffic. I can also use the watch in situations where the watch’s built-in speaker would be too quiet to hear. Even with the limitations I’ve mentioned , I think you’ll still find using your Aftershokz with Multipoint a productivity boost.
Oh, my mess of cables hack is still useful if I want to hear more than 2 devices; and with that solution, the audio really is simultaneous.

How I combined multiple audio sources into one Bluetooth headset

Back in the day  i’d have to hold the phone up to my ear whenever I wanted to use GPS or anything with the screenreader, and if a bus went by, it was   a complete   fail.    then in early 2013  my friend Hai Nguyen Ly gave me a pair of the Aftershokz 1st generation bone conducting  headphones and my workflow in public was changed forever. I could use my iPhone  anywhere and besides being able to hear it in any situation quiet or loud it didn’t bother anyone around me either.

 

The problems above were very similar with talking watches which is why until the Apple watch I had always preferred braille watches. I’ve found a lot of cool uses for my Apple watch but the problem of its audio coming out the speaker in public still remained.

 

Aftershokz came out with their Trekz   Titanium model earlier this year, and among other things in their marketing speak was mentioned Bluetooth multipoint; that their new flagship model could pair with 2 Bluetooth devices. I was excited, if i could get the audio from both my iPhone and Apple watch into the same pair of bone conducting  headphones that would be huge, but alas pairing with 2 devices did not mean simultaneously.

 

Over a year  ago my friend @cajunluke

told me about the Belkin  audio splitter Rockstar, and I’d also remembered Allison Sheridan and Dave Hamilton  talking about the Amtech Bean Bluetooth receiver, but it could only receive, if there was a bluetooth transmitter? A plan began forming in my mind.

 

 an Amazon delivery later I had a Rockstar and 2 Anker audio bluetooth adaptors  , which can both transmit and receive, though not simultaneously, and a bunch of patch cords and was ready to go.

 

The Rockstar has been out for a while and using it to combine wired audio sources is widely understood, but I was trying to  combine both  Bluetooth and analog audio  sources and also put them altogether, out to a Bluetooth headset.

I wondered how to combine 2 Bluetooth devices together when neither had a keyboard nor a display, but the Aftershokz and the Anker Bluetooth adaptor pair nicely as long as you remember to get them both into pair mode simultaneously it works most times.

 

One adaptor is set to receive and is paired to the watch. The other adaptor is set to transmit and is paired to the Aftershokz.

I wear cargo pants so the large pockets are great for a bunch of cables plugged altogether, the shorter the patch cords the better.

 

the system works very well, the more devices plugged into the Rockstar the lower the volume is because of resistance but so far there’s still enough volume to go around for me. Having the audio from my watch in the headset makes it much more productive for me in public even if no one was around to be annoyed by the watch speaker. When I used Apple pay  VoiceOver lowers the volume  for security, i could still hear it and much better through the headset. 

I also do BrainPort testing for Wicab 

and the Rockstar has 5 audio jacks so I can  plugged that in also which greatly improves how I hear it especially in loud environments.  

 

I’m surprised that seemingly few know about the Rockstar, but also haven’t heard of anyone combining it with Bluetooth adaptors. I know it will be part of my workflow for some time.
