Hello, I'm a new user here and of the iBasso DX120 which I purchased after reading many reviews/threads here and around the internet. I've learned quite a bit from hanging around here so thanks for sharing the knowledge. I write this post because I've owned my DX120 for a little bit less than a week and I find myself having to return it this week (hopefully for an exchange) because of 2 issues I'm having with it and maybe you can give me some advice...
1. The touch interface: I find my unit to be very sluggish and insensitive to input. I find myself having to press a button/area 3-4 times before anything happens and sometimes that action is delayed so much that it feels like the software gets hung up on it. On the play music screen the little menu button on the left side almost never performs its action, no matter how many times I press it. And the slider bar/button to FFW or RW, which it supposed to glide with your finger as you move it back and forth, has never worked for me. On the My Music screen menu (Directory, Album, Artist, Genre, etc.) whenever I try to swipe up and down to move the list it almost always registers my touch as input and takes me to that artist/album. It's frustrating to try to move up/down this function.
I've updated the firmware to the most recent version from the iBasso website and did 2 factory resets but it didn't do much to solve this problem. I've seen several YouTube reviews/videos of the interface in action and mine it's not even close to being as fluid as those videos show. So I decided on Sunday that I couldn't put up with it for much longer. I did contact both Penon and iBasso directly and decided that an exchange/return would be best at this point.
2. The battery: my battery gets warm, sometimes hot at certain times. The first day I got the player I used it (burn-in) and the battery drained from around 65% (when I received it) to about 18% 6hrs later. So I put it on the charger I normally use with my USB-C devices (ASUS laptop, Huawei and ASUS phones). When I checked it an hour later the player was so hot that I got scared and unplugged it and placed it on a cold granite surface to help it cool down. The player had been turned off before going on the charger, btw. Since that first night I haven't used that charger again, now I just use a Quick Charge phone charger. But I've noticed that the player still gets warm at times when I charge it, but never as hot as it got that first night. I noticed last night that after playing for about 2-3hrs (FLAC files) the player turned off because battery had drained completely. When I picked it up, it was warm again. After about 20 minutes of cooling down I placed it on the charger again and it charged to 60% in about 2hrs. I've been getting decent amounts of playtime out of it but I'm a little concerned with this cycle of warming up when playing or charging.
I apologize in advance for the length of my first post here, but I hope that you might be able to shed some light on the issues I'm having. I love the ergonomics and SQ of the device (upgrading from Hidizs AP60Pro), so I hope to be able to get a unit that works better than this first one.
Thanks for reading
