Stupid Bluetooth

Live Chat: Hello
Me. Welcome to LG Electronics U.S.A. Support only. How may I provide you with excellent service today?

Live Chat: Hi Me!
Live Chat: How may I help you today?
Me: Hello. Periodically, my headset’s microphone, when paired with an iPhone, stops transmitting.
Me: I am able to hear the other party just fine, but they cannot hear me speaking.
Me: I transfer the call to the handset, then back to Bluetooth, and they can hear me again.
Me: This has only happened with this particular headset – it does not happen with my Jabra or Logitech, when paired with the same iPhone.
Live Chat: I’m so sorry to hear that Me.
Live Chat: But I’ll do my bets to help you with this.
Live Chat: Have you tried unpairing the device to your phone, and pair it back again?
Me: Several times.
Live Chat: Have you tried pairing the device to other phones to see if it will also do the same thing?
Me: Unfortunately I only have one phone.
Live Chat: I see.
Me: I have paired it with other devices, but only those that play music (PC, iPad), not using the microphone, so I can’t reliably reproduce it with another device.
Live Chat: But may I know what iPhone are you using?
Me: iPhone 5S
Live Chat: May I know what is the bluetooth version?
Me: Sorry, I’m not sure what you are asking for.
Live Chat: The bluetooth version of your iphone?
Me: https://www.apple.com/iphone-5s/specs/
Me: According to that, it is Bluetooth 4.
Live Chat: Well for this one Me for us to determine if the device is defective, we need to pair it to other device. \
Me: Okay. I have it presently paired with my MacBook Air.
Live Chat: Our bluetooth headset only supports bluetooth version 3.0.
Live Chat: HBS-750.
Live Chat: Well this could be a compatibility issue.
Live Chat: But for us to make sure its not defective, we need to pair it to other device that has 3.0 bluetooth version.
Me: Bluetooth 4.0 is backward-compatible with all other versions of Bluetooth.
Live Chat: Yes, bit not the headset since it is only 3.0.
Me: Bluetooth 4 has been out for nearly 4 years. Are you telling me this headset does not work with any phones newer than 2011?
Live Chat: Here is the specification of the device Me,

<Note: This is the same page which I used to initiate the live chat session…>

Me: I see that. But Bluetooth 4 is backward compatible with Bluetooth 3. Nobody makes Bluetooth 3 phones anymore. Are you saying that this headset only works with Bluetooth 3? Notice:

Live Chat: I really do apologize for this.
Live Chat: But in case you device is defective, I can offer you our warranty service.
Me: Okay. How does that work?
Live Chat: Your unit has a one year limited warranty from the date of purchase. A receipt is needed to validate this. This warranty also does not cover physical, body, cosmetic or moisture damages to the unit.
Live Chat: If you paired it with other phone that has 3.0 bluetooth and it is still doing the same thing, I can offer you our replacement service.
Me: Well, that would require my finding and purchasing a 4 year old phone, which is a little more work than I’m able to put in right now.
Live Chat: No, we need the receipt for the headset.
Me: I will try to find a friend with an ancient phone to test this.
Live Chat: Actually an Android phone will do.
Live Chat: Is there anything else I could be of help?
Me: Do I have a case number or something to reference in case I have the same problem on a Bluetooth 3 phone?
Live Chat: I will document this case here under your account.
Live Chat: You just need to provide us you phone number for us to pull it up.
Me: Okay. SO that is on record as a result of this chat?
Live Chat: Yes Me.
Live Chat: Is there anything else I could be of help?
Me: No. Thank you.
Live Chat: You’re welcome Me.
