No. The two Soundgears can connect to the BTA, but not to each other. Also, when using one Soundgear, the use of aptxLL may result in a delay. If you are connected to two, the delay may be more noticeable, since LL is no longer active.

The difference is the BTA unit, which is a Bluetooth transmitter. The Soundgear BTA comes with the BTA unit in the box. The Soundgear does not. The BTA can be connected (with a signal cable) to a TV set, a CD player, or any other stereo line-level source, and can then stream this signal to the Soundgear wirelessly, via Bluetooth. TV sound or game sound are possible, since the BTA and the Soundgear use aptX Low Latency, which reduces the audio delay to levels, where picture and sound will be closely synchronized. This is also the secret behind the option to connect two Soundgears to one BTA unit, for two people to share a TV transmission, or a video game. Actually, you can use the BTA to stream to most other Bluetooth headphones and loudspeakers, but only if these devices also support aptX LL will the delay be low enough for video use.

Yes, all sources that output analog stereo line-level signals or stereo audio optical digital signals may be used, cable-connected to the BTA 20 transmitter. Digital signals must be in PCM format. So if you have a CD player or an FM radio, you can connect the BTA 20 to it, and transmit to your Soundgear (or to other Bluetooth headphones that support the format). Please note that record players need an additional preamplifier to work this way. Of course a TV set can be connected as well, either via optical digital PCM output, via line outputs or via headphone output.

While you have an incoming call, and you can hear the call-tone from your SoundGear, simply adjust the SoundGear's call-tone level to the desired intensity, using the SoundGear's volume buttons.
