[SOLVED] Will class 1 bluetooth help with interference ?

[tek3195]

Hi, my question is more about the user and not so much the devices. I have not been able to find a pair of bluetooth earbuds that will work for me. I have tried numerous brands with 4.0 and 5.2 and every version in between in the $20 to $80 range. They all cut out, drop signal, pop and at times disconnect. I have quite a bit of metal implanted in me and think it must be the reason. They don't work connected to any device I have, 2 PCs, 5 Android tablets and 4 cell phones. The sketchy connection is while holding phone or tablet in my hand. If I set the device down I can't get more than 3 feet away and disconnected. Wired sets cause problems for me and really want to find a wireless solution.

I've read that class 1 has a much longer connection range, but don't know if short connection would be a stronger connection. I don't know how all of that stuff works so I thought I would just ask. Would it be possible for class 1 bluetooth devices to overcome the interference from cobalt plates in wrists, chromium-cobalt shoulder and 44 pieces of titanium in my back ? Or do I need to consider bluetooth as a non-viable option and tell the wife tough luck, you get to hear whatever I'm listening to ?

More likely it is some other radio transmission interfering. Metal would have to be directly in the path to block it. Metal does not do anything other than block the signal it does not generate interference.

Part of the reason ear buds are not class 1 is the more radio power you have the more battery it eats. I have seen class 1 headphones since those can have much larger batteries. Also remember you really need both ends to have higher power. Even though it may seem the earbuds only receive they actually send some data back.

I guess I'll just have to be confused. I can walk out in the middle of a field with phone or tablet and they won't work. There shouldn't be any interference 250 yards away from everything.

The manufacturers that advertise class 1 earbuds should be shot. They say class 1 but if you look at the specs they only claim 10m or 30ft for connection. I don't know what they consider class 1 but they don't meet it.

Not sure the definition of what the different blue tooth classes are is very clearly defined. It is not so much a distance as it is a power output. The radio power is what actually affects the distance more than anything else.

It is things like the water vapor in the air that absorbs the signal and limits the distance.

They would be inconsistent...ie telling lies... if they said it was class 1 and only goes 10m. By definition a class 1 device goes 100meters in optimum conditions. Class 2 device only go 10 meters. So if the manufacture is claiming only 10 meters then it makes it class 2 even if they pretend it is class 1.

Still 10 meters is a lot and it should work. Class 1 takes almost 50 times the battery power than class 2 does so something like earbuds with tiny batteries are not the best candidate to have class 1 radios.

Bluetooth like wifi is almost magic in how it works or more how it doesn't work for unknown reasons many times. It can be the smallest thing. If you happen to put your finger in the wrong place on a cell phone and it blocks the antenna a bit it can drop connection to the cell tower.
