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.

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.

Can this be charged while in use?

Sure can. This little amp is amazing!

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.

音は値段よりもよいが、今時こんな使い勝手の悪いDACはないんじゃないのかなぁ

Amazonに在庫が無かったのでeイヤフォンから購入レビュウー Fiioって音のコスパ良いんだけど、使い勝手は悪いって印象を上塗りした製品。製品の仕上げが悪くて、手に持ってて嬉しくない。付属のカバーとか付けるだけかっこ悪いから付ける気も起きないの。よく言えば無骨、普通の感覚から言えばダサいか付ける気も起きない。残根なのは、こんな中華製品よりもよい国産品が無くなってしまったこと。せめて音は同等品で、手に持った時の嬉しさがある商品を出してくれる会社はないものか。それさえ理解して目をつむれれば値段以上の製品。でも持ってて嬉しいかと言われるとそうは言えないなぁ
