FiiO BTR7 Headphone Amp Bluetooth Receiver High Resolution Portable DAC Supports MQA/LDAC/aptX HD 384K/32Bit DSD256 for Phone/PC/Car/Home Audio

Q: Anyone know what the "charging off" switch is for? Why would I turn the charging ability off? The unit plays music fine with it off or on?

1) you need to switch it on to charge the unit. 2) you can set it to off to prevent it drains battery of your phone when you connect it (via usb-c not bluetooth) to your phone. 3) the unit plays music fine regardless of this switch's setting. hope it helps.

Q: For those on ios (iphone or ipad), are you able to save your 3 custom eq settings on to btr7 from fiio control? heard there was a bug.

This is bad advice. The app is extremely easy to use and the parametric equalizer is perhaps the best feature and the reason I purchased this amp. I use iOS and saving the settings is easy and practically automatic. The custom EQ is only adjustable through the app. I’m not sure why so many people have problems using it. It seems so simple to me. My only issue is when you reset the custom EQ to default (flat), it resets all 3 at once. It would be better if you could individually reset each one.

Q: Can this be charged while in use?

Sure can. This little amp is amazing!

Q: Will this product increase the frequency range of my headphones? currently 20-40,000 khz, will this get it down to 10khz and improve dynamics qualiy

Your headphones' current range is 20hz to 40,000 Hz or 20hz to 40 kHz. It is already past 10 kHz, and will not reduce it. What this device will do is improve sound quality with less background noise, or hiss and so more dynamic range.
