Is there an opening on the bottom where I can connect a bluetooth adapter?

There is a hole on the bottom. I'm not sure how big the adapter is. If it's the same size as the charger it should be fine.

It is through Bluetooth but not via the connector. I'm not sure about an adapter.

There is on the bottom of the ear piece, there's a little flap to open, check the photo again

The lip of the case extends about 1/16" beyond the phone around the jack. I'm able to get a standard 1/4 to 1/8 adapter into the jack to connect my headphones. I have to push a little extra to get a snug connection but not too much.

It has a hole to access the headphone connection on the I pad. Not sure if that was ur question.

Look at the end nearest to the ear piece. There should be a port for a mini-USB or a hole the charger cable plugs into.

The headphone plugin peeps out at the top corner, if you put the phone in that way. There's no 'official' opening, though.

The speakers are on the bottom of the tablet by the charging port and yes there are openings where they are located. The only other opening is on the back where the camera is located (speaking about the Samsung Tablet 3).

Actually there is a long hole on the bottom, where I can access the headphone jack and the lightning port. But there is another hole at the top, at the same place of iPhone 4 headphone jack.

Yes. The bottom has openings for the charging cable, headphone jack and speakers

The bottom is open. You can plug in the charger and it should fit in a dock.

No you cannot unfortunately. The bottom of the case causes the adaptor not to fit

No, It does not. There are not yet any available accesories such as a dock or speaker dock, or for that matter anything that plugs into the proprietary connector on the bottom of the device. This would lead most to believe that there will eventually be some kind of accesory like this

The 3.5mm input jack is on the right side of the adapter. It's black in color so it may be difficult to locate at first glance. I use it for my MP3 player. I do not believe this device is Bluetooth compatible. Hope that answers your question. Enjoy.

There is no hole in the bottom that a straight connector could go thru. However the sides at the bottom edge are open and if your headphones have a right-angle connector it might work.

There is a standard earphone jack under the little rubber flap on the end of the unit. I have not tried it myself, but it's there.

There is an outlet but it's very small. My headphone's plug is too large to fit.
