Thanks for all the responses ! So, at this time, Hifi-M8 V2 provides 1.6 W per channel @ 75 ohm. With this new dedicated amp, it hovers about 2 W per channel, based on battery constraints. Why don't we have a larger capacity battery to handle this extra power driven battery consumption ?
What volume level is the battery tested at ? If you say 80 dBA average (which occurs at half the volume dial), low gain and battery only lasts for 4-5 hours, could be quite concerning. It is not just about the loudness, but how certain regions in the audio spectrum (bass specifically requires lot more power because impedance curve is non-linear) are being properly excited with enough headroom.
ATH-R70X is classic case for this.
We are running a variety of tests under many conditions. It's early to make assumptions. Battery is quite large but so is the output power. And at some point any battery will be depleted. The math is simple.
The real issue is the multi-parametric optimization. That's to say, you have-real world product size, real-world battery, real-world cans and real world music. Also, real world people... Add to that the amps and power supplies, which are not 100% efficient. Given the above, the goal is to choose the best customer experience.
We understand the engineering variables. At CAN JAM we plan to understand the human variables, i.e., musics, headphones, loudness preferences, etc. Like how many people actually get on a bike wearing $5k cans. After that, we should be able to strike an educated balance.
