This is the BEST bluetooth I have ever owned.
I had the H710 before this, but my car was broken into and it was stolen. I immediately purchased the newest model of the same Motorola series - this H720 - and am thrilled with it.
First of all, this bluetooth does NOT stick INSIDE your ear. I can't stand the bluetooths that do that. This unit has nothing to stick inside your ear. It is flat and lays flat against your ear. It is also loud and clear so you don't have to worry that you're giving up on sound. As a matter of fact, sometimes it's too loud and you can lower the volume easily. The sound is nice and clear, and there is no lag time - you don't miss the first few seconds of the conversation - it picks up immediately.
The other thing that I really like about this unit is the flip open design for turning it on or off. You flip it open to turn it on, and flip it closed to turn it off. Simple. No guesswork involved. I love the simplicity of it.
This bluetooth has a GREAT battery life, both for talktime and standby.
Another improvement that I really like for this bluetooth over the H710 was that they changed that big round light ring, and replaced it with a small dot light. This way I don't walk around looking like I'm a plugged in robot (as I am WEARING this and the H710 would blink as I walked around!). On the H720 there's a little mini dot light which is enough for me to see if the unit is on or off, and is enough for me to see if it's red (which means that it needs to be recharged). Great design improvement! I can look like a human and not like a blinking android.
And another nice feature is that it sounds a tone when the bluetooth battery is running low and needs to be recharged.
Once you use this bluetooth, you wont want to go back to any of the others on the market. I'm spoiled now and can't imagine ever go back to using the others out there. This one is a keeper!
