I got a Motorola S705 and I am pretty happy with it...

This should work. My understanding is that miniUSB is a standard and all devices are interchangeable electrically.

My experience is that if some "chargers" (or USB ports) aren't compatible with some devices it just won't charge them, I have never burned any devices by plugging them with other chargers, etc...

Now, as the title of my reply says, I've returned my BT3030 and I got a Motorola S705, for less $ and it provides more functionality! Here is a quick review:

The pluses so far:

- Mini-usb connection for charging (again, important to me, as I like to minimize the number of chargers I take on the road)

- LCD interface. It's just basic menus, but at least you know exactly what the device is doing instead of trying to decode a combination of LED colors and blinking rate (like on the BT3030)

- Radio... I didn't think I needed it, but it's actually pretty handy. A couple of times I was listening to a radio show in the car when I had to get out... I just tuned the S705 to the same radio station and off I was, show uninterrupted

- Joystick control: I was concerned early on that this would be a pain, but for my use it actually gives me a better control / feel (I use it mostly riding my mountain bike, so I have to be able to operate it with gloves). On the BT3030 I always pusked the wrong button, with the S705, the buttons for answering the phone is on the side and the joystick controls the audio functionality.

- Volume: the S705 can definitively crank out more volume out of the same headset than the BT3030. Not by much, but enough to make worth it (volume issue was a deal killer for me on the BT3030). Note on the volume issue: it will probably not be a problem for most people. What I found out is that the podcast that I listen to most frequently are actually recorded pretty low compared to other podcasts and regular music. Since I have yet to find an automated way of doing volume leveling on podcast (iTunes can, but it ain't compatible with my phone), this has been a key issue for me.

- Headphone jack positioning: on the S705 the headset plugs in at the top of the devices, just in front of the lanyard. This is great if you have a headset with a straight jack, as you can wrap the headset cord around the lanyard, up to your neck and keep the wires from dangling all over the place. On the BT3030, the jack in on the side, which I think would be goodif you had a headset with a right angle jack.

Neutrals

:

- Battery life: seems pretty good, but honestly I haven't pushed it. I am sure I'll run out of battery on my phone (ATT Tilt / HTC Kaiser) before the S705 runs out.

- Durability: the BT3030 was "splash proof" and had a nice solid feel with the rubber thingy around it. The S705 feels more fragile, but I've had it during a couple of wet rides and it hasn't been a problem so far. Time will tell.

- Sound quality: good enough for my application (listening to podcasts and music will I ride my mountain bike. These long grinds uphills get really boring really fast without it!).

- Range: not critical for me as my phone is in my backpack or in my breast pocket, but I've been able to get 20 feet a couple of time where I had to walk away from the phone. Good enough for my application!

Cons

:

- Bluetooth connection? I've had some instance of Bluetooth connection dropping on the phone side. This is weird because the symptoms are a dropped connection and when I look at the phone, bluetooth is turned off. I just need to turn bluetooth on again and everything works again. I've never had that happen with other bluetooth devices before on that phone, so it would point to the S705, but it doesn't make sense to me...

- Fast FW/ Rev: not sure if this is an issue with the device, the BlueTooth remote control profile or the music player on the phone, but there is no fast forward / reverse functionality. Hitting the >> or << function either with a stab of a continuous push only skips the the next / previous song. I had the same problem with the BT3030 and it's a pain when listening to podcast (where you might want to listed again to a section of particular interest or just skip over something boring).

- Lock switch: it would be nice if there was a switch to lock out the buttons to prevent unintended operation.

Overall 4.5 stars out of 5, so far so good! We'll see about the durability!
