Battery life using what card? People have to sure they're speaking on relevant terms with such a 'diverse' device.
Its a brilliant player regardless of the few set backs, have no doubt they'll get there with it all.
In re the EQ setting....

Hi,
Our engineer said they were considering this, but this function may not complete in near future.
That's OK that you purchase AK120. It is quite portable.
If we can be of any assistance, please feel free to contact us.
Best regards,

Having a flat sound is an option you can have as part of an EQ option to colour the sound to your tastes/needs etc, there are too many instances to think of where a person might want to bring forward or recess a certain part of a recording, we aren't all consumers of music, some produce it, some listen to field recordings etc having something is far better than it not being there at all.
