- 3.5mm Jack: No
- 4.4mm Jack: Yes with slightly noise and only happens during power on/off stage.
And you might wondering why 4.4 balanced headphone jack with slightly pop noise when powering on the Tone2 Pro while the 3.5mm one doesn’t have?
The 3.5 jack is designed with a depop chipset to cancel the pop noise with 2.3Vrms output maximum.
While the 4.4 balanced jack targets to drive higher impedance headphones with higher output at 5.0Vrms and higher performance, the depop chipset will draw down the performance and also not support higher output.
We didn’t found a depop chpset can match the demand of of both performance and (up to) 5.0Vrms output the time we designed the Tone2 Pro.
