My TV or Bluetooth Transmitter will not pair with my OontZ Angle 3.

We have found Bluetooth from TV’s and Bluetooth transmitters often have compatibility problems. We find that some don’t work at all and others inconsistently. In general, our finding has shown that the version of the Bluetooth transmitter is important for compatibility. Bluetooth 5.0 transmitters don’t work as often as those that are classified as 4.2. The Bluetooth 4.2 version of transmitters have a higher level of success in connecting with Bluetooth speakers with 4.2 Bluetooth chipsets. The Bluetooth chips used in the transmitters are not as fully compliant as those used in smartphones for example, so sometimes there is an incompatibility in the protocols used between the transmitter and the speaker. If you find another BT Transmitter that is specified with 4.2 Bluetooth technology, it might work better than those with 4.0 and below or 5.0 Bluetooth technology.

Can I connect two OontZ Angle 3 speakers together to play in Dual Stereo

The OontZ Angle 3 does not support connecting two OontZ Angle 3 speakers together wirelessly or wired.

The OontZ Angle 3 can be connected to a single device with Bluetooth or with a 3.5mm audio cable to the Aux In of the speaker.

Is there replaceable batteries for my OontZ Angle 3
