AT&T Cingular Flip IV (U102AA) Compatible Stereo Headsets ?

We'll be happy to assist you with your Bluetooth @JimmyJJames.

The Cingular Flip IV uses Bluetooth v4.2, so it's possible that your headphones are compatible with v.5.0 and may not work. Just to make sure, make sure you're following these instructions when you try to pair devices to your phone. 

Please let us know if you have any additional concerns; if so, we'll be happy to assist. Thank you for reaching out to our AT&T Community.

Which Bluetooth Stereo or 2-Ear Headsets are compatible w/ the "AT&T Cingular Flip IV (U102AA) Flip-Phone",... ??? And, which Bluetooth version is required,... ???

I went to your instructions link, & it is the exact same page I had followed to pair my headsets. I've done it many times, but not a single time was I successful. 2 of my headsets I purchased at amazon & are most likely made in China & I don't have any documentation to be able to know their version, but they are a few years old. However, my best headset is even older, a Motorola HT820, of a better sound quality than the other 2 & way over 10 years old, that I got when I had my Motorola Razor cell-phone. However, my previous Samsung Rugby 3 had no issues w/ any of the headsets - it found the all. Now the question is, Is the Flip 4 Bluetooth backward compatible,... ???

Something that old is probably the problem.

Ok then,... So which stereo headsets are compatible w/ the AT&T Cingular Flip IV phone,... ???

Hi JimmyJJames! Let's address your stereo headsets Bluetooth connectivity concern with your AT&T Cingular IV flip phone device!

Please ensure that your stereo headset Bluetooth is on to enable your device to find it when Bluetooth is turned on the device. As the previous agent stated your stereo headset may not be compatible to your device's Bluetooth. Please use the headsets that are compatible with Bluetooth v4.2. 

We hope this helps! Thank you for reaching out to the AT&T Community Forums!

Ok,.. So I ordered a new Bluetooth v4.2 headset w/ built-in microphone & will see if it finds it. If it does, then we'll know the "AT&T Cingular Flip IV" phone offers no backward compatibility (which is what I suspected), & it only supports Bluetooth v4.2. I'll let you guys know in a couple of days when I receive my headset how it went. So far all of the answers were good, so it's going to be hard to pick one,...

The "AT&T Cingular Flip IV" phone connected & paired w/ Amazon's RTUSIA Small Bluetooth v4.2 Headphones w/ Microphone (Headset). However, it wasn't easy, & it wasn't as simple as depicted in the help page. I ran into some issues I will describe in the following comment.

This are some of the issues I recall finding, although there might be more,...
___ You have to go to Settings (SET), NC (Network Connectivity), BT (Bluetooth), PD (Paired Devices) to [Connect/Disconnect] from your HS (HeadSet), so you have to be connected to your device (i.e., headset) before you can make or receive a call. The problem w/ this is that you can't temporarily turn-off your HS to save the battery power of the HS, since you don't know when you'll receive a call. Therefore, you should be able to turn ON your HS, once you get a call, & have the phone automatically connect to your BT HS device. My Samsung Rugby 3 had all of this in 1 simple screen, where you could see all of the devices you could connect to, & you could see which 1 was connected, & you could individually [Connect/Disconnect] to any 1 of them in the devices (i.e., headsets) list. In addition it could "automatically connect" to which ever headset you turned ON - in my opinion this is the way it should work - easy, not complicated.
___ Even though the Marathon HeadSet (Amazon's RTUSIA Small Bluetooth v4.2 Headphones w/ Microphone) connects to the AT&T Cingular Flip IV, you can't see it connect in the SET-NC-BT-[Nearby Devices], you have to go to the [Paired Devices], where it shows "Marathon" in the "paired devices" list.
___ Another problem I ran into is that, while attempting to BT-[Nearby Devices][Scan], often times the BT got automatically "turned-off" (BT = Off), & so I had to go back & manually turn it back ON (BT = On). This is pretty annoying.
Overall I am not satisfied w/ the way the software handles connectivity to BT HeadSets, as it is cumbersome, not intuitive enough, not easy enough, & unexpectedly turns off the phone's BT w/o any rime or reason.

I have a galaxy s9 plus and can plug in my head phones that go around my ears can you plug in the head phones into the flip phone,
