My First Dap

[u/ailyum]

Fiio JM21 with Kefine Delci AE.

I never thought I'd get one to be honest but I go on daily walks and listen to music. And I realized I don't want to carry my phone every time.

So, I looked for lightweight DAPs and ended up with Fiio JM21. And for the IEM I was looking for something that could play R&B music well and is also around my budget so I got the Kefine Delci AE using the silver nozzle.

I love it! Although I didn't know that using the IEM drains the battery that much even if I have battering saving on, low gain, wifi off and the songs are downloaded. Still worth it tbh.

You may want to put it into developer mode and turn off the gyroscope sensors. That saved me tons of battery on my DX180.

I was struggling a bit with the battery it and that’s what I feel helped the most.

Oh i will try this. Thank you. Once I figure it out haha.

No problem! The battery life should also improve after a few full recharge cycles as well.

Try this guide to turn off the sensors:

Steps to Turn Off Sensors
Open Settings on your device.

Go to About Device and locate the Build number.

Tap the Build number seven times until a message says you are a developer.

Go to System and open Developer options.

Tap Quick Settings Developer Tiles and turn on Sensors Off.

Swipe down from the top of the screen to open your Notification/Quick Settings area.

Tap the Sensors Off tile to deactivate all internal sensors.

Thank you

Sensors are already off on that page. Looks like everything is.

I never went and messed with this page on my M21, so I don't think this is necessary.

Sensors off needs to be turned on, that enables the tile in your top pull down menu to be enabled then you can officially turn off the sensors using the toggle that appears.

Got mine a few months ago. I've been loving it so far.

Right! It just feels so nifty. Also love the headphones, the color specially.

I love Wand!

I just got mine a few days ago. It doesn't play well with my car's Bluetooth (need to manually connect each time) but I think that's an issue with my infotainment system. In general, I love the unit and how easy it is to navigate my 600gb collection. I use Symfonium as my player/media manager and have no regrets.

Oh, I also have connectivity issues with bluetooth sometimes.

It seems like the only negative about the JM21 is the battery life…how fast does the battery drain when it’s in standby mode?

[u/ailyum → u/Typical-Gas1946]

Like 3 days but that's with battery saver on.

[u/Typical-Gas1946 → u/ailyum]

I’m assuming that’s with WiFi and Bluetooth off as well correct?

[u/ailyum → u/Typical-Gas1946]

Wifi Off. Bluetooth On. But from what I have remmebered I used it for 2 hours (separate occasions) with bluetooth earbuds.

Tengo los mismos equipos y estoy encantado , disfrútalo

[u/ailyum → u/Pat-Jr]

Yes! I love how light it is and how easy/fast it is to navigate.
