Anyone use headphone out + bluetooth transmitter = In ear monitors?

Recommended Posts

Just wondering if anyone has tried to use the headphone out connected to a bluetooth transmitter like this: 

Amazon.com: Bluetooth Tranismitter

Then, simply pair it up to your Bluetooth headphones and you have a cheap on-stage/rehearsal in ear monitor for yourself? 

Would that work?!?

 

**EDIT** I found a solution that works for me, see my detailed reply below

I had that same BT transmitter for awhile and was using it with BT earbuds in my workout room for my TV. Even with movies and whatnot, I could still notice the latency sometimes. It probably wouldn't be viable because of that for guitar.

Dang that makes me sad! Would have been soo easy

Typical Bluetooth latency is horrible... sometimes as much as 500ms. Totally unusable for this application.

Sadness. Any ideas for a cheap, 1 user in-ear use to monitor myself when playing?

Depends on your definition of "cheap"... and generally speaking, you get what you pay for. Cheap usually sounds like $hit...

Cheap meaning affordable without paying extra for overkill. Yes, it does - but again I'm only looking to monitor myself. Ideas appreciated.

Anything wireless is going to be a crap shoot. So many things can factor into wireless, latency, interference, rf signals that can jam or block the path, heck even fluorescent light bulbs can cause static on a wireless setup. If you want to monitor yourself clean, clear, and on time then some high impedance cans would be the best way to go. A good 250 ohm set of beyerdynamics would really sound good. If you absolutely must go wireless try to take some time and prepare the area that you practice in for a wireless signal. shield whatever you can,  hide your cell phone and turn off other electronics in the room. It may help SLIGHTLY with rf interference. But I doubt it will be perfect. There is a cost/benefit to everything man. Wireless is convenient and comfortable. It's also susceptible to latency and rf noise.  It's worth it in some spots, not in others. I recall once about a year and a half ago, I was rehearsing with the guys and suddenly everyone stops and goes "wtf is THAT??" I stopped and played it back and heard ..pop pop pop pop buzzzzzzzzz.  My phone was receiving text messages and the signal was being picked up on the wireless channel.  The point is, depending on your situation wireless may be a god-send. Then again high impedance cans with a really long extension cable might be cleaner. If you were just alone in a room Bluetooth probably wouldn't be that awful. It's when other people are in the room that you might have a problem. Not to mention the wiring in your building could play a role, how close you are to other appliances, even other equipment in your station. Wireless just puts so many variables in the mix. Like so many.

I’m using a wired Behringer Powerplay P1 for my in ears. Short XLR cables from my Helix to the powerplay which is mounted on my pedalboard. And then a DIY snake with guitar cable and headphones extension cord of approximately 6 meters.

This enables me to monitor my Helix in stereo during rehearsal, use a stereo send from the monitor mixer or receive a mono signal from the monitor mixer and mix it with my own guitar signal when gigging.

 

I figured that, when using my Helix, I have to use the pedals frequently, so wireless doesn’t add anything. My 6m cable gives me enough walking distance.

OP Here.

 

Thank you all for the replies.

 

Against all odds, I went ahead and purchased about 6 or 8 bluetooth transmitters & receivers from Amazon hoping to find a combination that would transmit with minimal delay using the AptX "low latency" profile... I tested each/every combination yielding wildly different results (all items had Aptx profile capability). 

 

I FOUND A COMBINATION THAT WORKS!

 

This Transmitter:  https://www.amazon.com/gp/product/B01B4W40VC/ref=oh_aui_detailpage_o05_s01?ie=UTF8&psc=1

This Receiver: https://www.amazon.com/gp/product/B073DZMWD1/ref=oh_aui_detailpage_o05_s00?ie=UTF8&psc=1

 

The transmitter is plugged into the "headphone out" of the Helix. Then I have a standard pair of wired headphones plugged into the receiver. I had to use a 3.5mm to 1/4" adapter to allow the transmitter to plug into the Helix.

 

There is still a very slight delay, but not enough to throw me off. I put my wired earbuds in, then put a generic pair of sound reducing cans over my ears when practicing w/ my band in the loud lollipop basement. 

 

Given the nature of Bluetooth, it's possible that YMMV but I'm tellin you guys.... I LOVE IT!

Thanks for the research! From the product page:

 

Quote
  • The latency of 40ms is still unacceptable for live sound monitoring. Therefore, musicians beware! Bluetooth technology, even with aptX Low Latency, may not suit your needs;

 

I can deal with 10-20ms delay on a guitar feed, but for voice, it's a showstopper. Glad you're having fun with it!

The first combinations of products I tried were indeed horrible (even though they all supported aptX), but the specific combination I linked above is definitely acceptable. Those two devices just "get along" faster than any other combination I tried. Again, I spent an hour trying all different combinations and indeed NONE of them were close... except the two products I mentioned.

I bought these and I will say they work flawsly for my needs.  I do not experience any latency that I notice.  The IEM market needs to respond to the market place for good wireless IEMS with a "sexy" small footprint like they have done in the guitar world.  Thanks khall187 for the research.

Hey there! 

Did you try some of the aptx headphones os Avantree instead of getting a receiver to plug the headphones?

Thanks for the research man, I'm in the same place now!

I'm trying another combination, as I wanted a "Class 1" transmitter capable of further distance, while still being AptX LL. There are many ~$50 ones that look like they're the same build, but this was on a "lightning deal" for $35:

https://www.amazon.com/gp/product/B07JZH47B3/

 

I thought about the Avantree receiver, but figured I'd try a FiiO because of the good reviews of its sound quality:

https://www.amazon.com/gp/product/B07JM5ZQPF

 

I'll post how well they work...

Thanks for posting.  The only issue I have is that my PA has a bluetooth channel and the darn transmitter auto joins that instead of my IEM receiver and honestly they do not pair super easily.  Thank for posting updates to this thread.

I got my toys. I think the delay with this combo is likely in the 30-40ms range. It bugs me, so I don't think I'll use this for guitar, but I do think it's in the "YMMV" range. It does work great for its intended use - keeping sync with video. It doesn't bug me there (though you can usually adjust sync in modern media player software anyway).

I measured these. The FiiO gives me 40ms delay. My generic $15 non-AptX receiver is 130ms! So, definitely an improvement. I'll stop bothering you guys now... ;-)

OP. How did you connect the transmitter to the receiver? Do they just pair with each other? What is the interface the is connecting the two?
