Hello, about btr3k when using as usb dac and have not CTIA headphones does dongle mic work? If I am on bluetooth and run out of battery will I stay on BT when plugg to usb port or it will go as usb dac? If instead plug on powerbank?

As USB dac, have it a microphone operation? I mean if we have a 4-pin trrs will it use its mic (as external soundcard)? Also, can i have it working in bluetooth mode while charging from PC or it will go automatically to USB DAC?

Just received mine silver from amazon de. They have an L eding cable.

I have tried iconx 2018. Samsung really solved the Master slave issue all other Have. Sq is good well balanced Only when on board playing I did not have good fit on running. Other manufacturers should offer the same (on board and no master slave)

I bought finally a Z5 and indeed has apt-X. Sorry, for confusion that has been done.

I have Z1 compact and it also supports apt-X and a message is displayed upon connecting. It is weird that Sony and Qualcomm apt-X does not list the Z5 phones as the ones having apt-X Check at https://www.aptx.com/products?field_product_brand_tid=25   Althoug i see the Xperia X having LDAC as...

Does the Z5s do apt-x when headphones are apt-x or they do SBC? Official site of Sony and of apt-x say nothing

What about using the dac to output from it digital out? Will that be the same quality wise with just using the digital out from laptop?

So, the USB processing does not by-pass the music player equalizer? So, the audio quality is not affected by the extra processing of the equalizer?

Probably a silly question: why bother buying any other DAC that does not have an equalizer? Most of other DAC offer at most a bass boost and that's it. How to fine tune the sound, when using a USB DAC other than Creative ones?

Still unanswered and i have a 5th question:   When in USB mode with PC can E5 be used as Bluetooth transmitter (with apt-x LL)?

Read whole thread and some questions that have not been done yet: 1)Over bluetooth there are 2 options, either stereo or pcm output via toslink? 2)If pcm output it is a pass through signal to be driven 'untouched' to an amplifier (Direct ouput)? 3)Or better to connect amp with stereo rca in...
