I have been using these types of headsets since the early 1990s. The KX-TCA93 are the best headsets I have ever used. I have not had any issues during use. Sound is good and I have no problem with them fitting around my ear. I have three telephones and use these headsets on all of them.
Product was a lot smaller than expected and fits even better on my desktop than originally planned. Has an on/off switch on the bottom of the microphone and can detach from the base. It isn't the best at picking up my voice, but it gets the job done. Perfect for using Skype or other communication programs.
These bluetooth - wireless headphones are great. They haven't failed me yet during running or HIIT workouts. I use them for about a week at a time before recharging them (I'm at the gym about 60 minutes each morning Mon-Fri). Turning them on and connecting to my iPhone is very simple. One you connect them once, the next time you turn the headset on it reconnects to the phone (where it was last connected) automatically. What I wish were better were the sound quality. The sound is good but if there were a little extra bass & treble it would make these so much better.
The KX-TCA430 headset does not say it is 'Bluetooth' so how can you criticize it for not being 'Bluetooth'? This is a corded headset. It connects to a 2.5mm headset jack in cordless or corded landline phones that, of course have the headset jack. The 'Bluetooth' on the KX-TGE260 phone is for connecting smartphones and 'Bluetooth' headsets. You can search for 'Bluetooth' headsets to find the right one for your phone(s).
