Trouble with Bluetooth Devices

Question

I have a MacBook Pro 13" from late-2011.  Recently I have decided to use Bluetooth headsets instead of wired earbuds because I tend to forget they are in my ears and when I get up, they are yanked out of my ears, hurting me and potentially pulling my notebook off of something.  I had an LG Tone before getting my current Motorola S11-FLEX HD headset.  I switched because of the problems I have been having with Bluetooth but switching has not solved the issue.
My biggest problem with my Bluetooth headsets is that the audio stutters and then de-syncs with any video.  The de-sync can be as bad as a full second.  I'll see the video's actions before I hear them.  The de-sync also affects the responsiveness of controls.  After I give a command, the audio will continue to play for however long the de-sync is before the command is performed.  It's like it's making up for the lost time.  The only solution I have come across is turning off the device, then turning it back on but that only works some of the time.  Usually, I have to turn it off and then on again two or three times before the de-syncing issue disappears.  I have no idea the cause as my LG Tone works to specifications with devices that belong to other people.  I have found that moving my head in a certain direction will cause the de-sync.  Sometimes, it's leaning back; other times, it's tilting my head.  It's as if the Bluetooth field is planar and I'm jumping out of the plane.
Another issue is the distance I can be from my device.  My Bluetooth headsets boasts being able to function perfectly as far as 30 feet for one headset but moving even 5 feet will cause the previously mentioned de-syncing if the audio is playing.  If I pause the audio, I can move about 10 feet.  After I move 10 feet, when I press play, the de-sync appears.  It renders the function of being wireless to being useless.  I wanted to Bluetooth so I didn't have to pause, take off my device, do what I need to do, and before coming back, putting on the device, and resuming play, hoping that nothing has gone wrong to cause a de-syncing issue.
A third issue I have is that sometimes, while listening to some audio of some kind, another program will make a noise causing the audio to cut out.  My notebook or the web browser is not aware that audio is no longer playing.  It's as if the new program has muted the original audio.  The only cure: turning off the device and turning it on again and hoping it's working.
The last issue I can think of is that when I turn my notebook off for any reason, all Bluetooth devices are forgotten causing me to go through the hassle of repairing the devices again but many times, the repairing process fails and despite being on and not paired to anything else, my notebook is unable to pair unless I turn both the device off and my notebook's Bluetooth off before turning both back on.
Has anyone run into issues like this? If so, does anyone have any recommendations on how to correct the problem? The problem is on my notebook side as the devices work fine with other products.  The LG Tone could be used across the house when it was attached to my father's Kindle Fire and when attached to my iPhone 5, I could walk 20 feet with doors and concrete between me and the device before any issues began (both devices had trouble with my iPhone but pausing usually fixes the issue so I don't care).  Please, I need some advice and help.

Some details missing.
I have a Pioneer DEH-P7000BT. On telephone settings, everything OK.
When I want to sync to my Audio Bluetooth, I hear the sound in slow motion :-)
I have to delete the Bluetooth device on the radio, and re-syncing on Audio Devices and everything fine.
Same thing all the time.
When I had iOS 3.1.3 on my iPhone 3G, everything was OK.
I can't find Firmware Update for my radio.
