Bluetooth without lag

[Bikeguy57]

I'm looking for an amp that will Bluetooth to my coclear implant without a lag. Wired headphones no longer work for me. I tried a digital interface into my computer, the tone was great, but the lag was too long. Any help would be greatly appreciated.

Bluetooth has allowable latency as part of the Bluetooth standards. It’s not the right system for low latency audio.

What other inputs will your implant accept?

This. Unless your implant has one of the newest low latency codecs, (something with a latency under 40 ms), you will notice the delay. Find out what codec is used for your implant would be the first thing to look at.

None, unfortunately.

None, unfortunately.

Then that’s going to be problematic.

Is a low volume amplifier or near field monitor an acceptable solution?

Yeah, there is going to be lag in BLE.
But a part of that lag may be coming from your interface. Check there first and maybe you can see enough improvement it won’t be a problem.

The latency of the interface is insignificant compared with BT.

BT generally has up to 240mSec of inherent allowed latency which a WAY too long to play with. Anything over 20msec can start becoming an issue.

Some implementations of BT 5.3 (I think) have ~40mSec of latency but it can vary depending on the connection and both the source and destination have to be compatible too. I have tested several BT5.0 devices and they were always much greater than 40mSec, generally greater than 100mSec.

It's a very loose standard in regards to being a consumer protocol and the need for extreme backwards compatibility.

Honestly, there is no way any current BT device can get down to an acceptable latency. It is simply not a compatible technology by modern standards. If headphones won't work with the implants, I can't think of anything other than letting the implants amplify ambient sound. That, I suspect, will require some sort of near field monitoring with a speaker.

...Or maybe a bone conduction type headphone that doesn't go in the ears?

Thanks for all the replies. I wonder if a low output amp like a spark or Phil Jones would work better without overwhelming/clipping my devices. I do have a streaming device that works with the ambient sound. Even my Rumble 100 overdrives them.

40 msec is a lot more latency that I would be happy with in my signal path - a couple msec is more what I'd call "low latency" for bass guitar use.

A big amp should go just as quiet as a small amp. volume knobs go down to 0. Reducing the bass level may help with not overdriving them .

Yea, I just thought maybe 20 watts and two 5 inch speakers would be more friendly to my streaming device.

Is there a neck loop transmitter that you could use? There's got to be something you can actually hardwire that will interface with your T coil.

 

[VeryTallBassist]

What about something like this that you could plug into the headphone out of your amp?

Interesting thread

yeah, anything above like 10ms latency will be pretty much unusable for live monitoring

 

[InstantEctobass]

Audio Interfaces should allow for a short latency like between 5 to 15ms on average. You probably didn't set it right? If you need help, I'm sure we can help you

What possibly might work is bass wireless system connected to portable headphone amplifier and head/earphones

Big amplifier -> wireless transmitter -> wireless receiver -> portable headphone amplifier -> wired headphones


I am not aware what is your condition and whether you don't use wired headphones connected to "big" bass amplifier or you don't use any kind of wired headphones, no matter what are they connected to


Twenty years ago Philips made wireless headphones with radio or infrared connection.
You still might find some

I had SONY ones for TV, the lag was rather noticable sadly
