Too bad this was the only daps on the market with a replacement battery, it sucks companies don't listen to us customers, I mean I understand all people with iPhones have no need for replaceable batteries,that's why apple started that trend in electronics all those years ago,but it is too bad for people like me, my wife got a dx50 and she loves it, we looked at the newer ibasso line up and realized that they don't have that option, I think we will buy another 1 or maybe 2 just for parts, thank God for all the amazingly good diy daps out now, at least I can change the batteries on my zishan all on my own,but it's not the same as my wifes ibasso, I have to solder it in, but she can simply drop in a charged one and keep moving, I wish they would have kept that feature, I was ready to buy a new ibasso but I guess I will stick to my cheaper diy stuff
