As a new-comer to headphone use I am slightly confused so thought I’d ask the collective wisdom of the forum:
I have wireless bluetooth noise-cancelling headphones (Sony WH1000-XM3). They must therefore have an internal battery, some form of DAC and amplification built-in. If I use them wired I assume the analogue signal is fed to the DAC for noise-cancelling, then onto the internal amp? This being the case how does the DSP/internal amp work with the incoming signal when using a Headline (or similar). I imagine the DSP and internal amp have the potential to act as a bottle-neck and degrade the signal from the Headline?
The incoming analogue signal will pass through an ADC then be processed by the DSP, same as a Bluetooth input, then onto the DAC and inbuilt amp etc.
Chances are this will be a slight degradation against a pure cabled analogue only solution. However wireless and noise cancelling bring their own benefits which cannot be ignored.
I’m very happy with NAC72 > Bluetooth Aptx HD transmitter i> Sony WH1000-XM2.
