the following will cover the braven r–1 bluetooth speaker. A description will be covered , followed by pros and cons.
The braven r–1 bluetooth speaker is about 5 inches long and maybe 2–3 inches high. There are 4 buttons that operate the unit. Both sides are sloped On the left top slope is volume up and down. You can skip back and forth with these 2 buttons, just hold them down.  On the right hand side is power and play. Hold down power and turn it on. You will get a low bass tone that is the same pitch as the droid sound.
The play button also acts as the pair button. To pair a device, hold down play for about 3 seconds until you hear 4 slow beeps that echo, twice. Then follow the directions on your device to pair. If you need to enter a code enter 4 0’s. The play button is also answer and end. If you need to answer a phone call, you hold down play.  To end the call hold down play. If no bluetooth signal is present the unit will shut off after 0.5 hours. To turn off the unit, hold down power for 3 seconds. You will hear two tones an octave apart. Warning, they can be loud so turn the unit down first just in case.
On the back of the unit is a cap. Unscrew this to access the other ports. You will find a regular usb 2.0 port that is for charging a device. And a micro port for charging the unit. You will also find a button that shows the battery indicator. There is also a reset button but I’m not sure yet where that is. On the left hand of this circle next to the usb port is the aux port. Use the provided mini patch cord to plug it in. If you need a longer one I’m sure best buy has them. Screw on the cap to make the unit water resistant again.
I love this unit. It is loud and can cover a midsize room. I’ve done it when I’m cooking and the sound is excellent. Not much base from a mono speaker, but enough to make it heard and sometimes felt. The speaker is lite weight and easy to carry.
The only con I have with it is it cannot do sd cards or even micro sd cards. Over all though this is an excellent unit.
If I have forgotten anything please let me know. Over all the speaker is a very good sounding speaker and I recommend it to anyone in need of something small.
Note, this will not work everywhere. For example in vlc you cannot skip, nor in the quick look. I had the opportunity to test this in some places and it works fine. It is trial and error.
the code comes from the manual which you can download from braven’s site. The pdf is accessible to voiceover users. It will take trial and error to learn the buttons.
A note to voiceover users. For some reason when a call comes in the phone does not pipe the voiceover and the ring through the speaker. This has been an ongoing issue since about iOs 8 or so.
