ATH-DSR7BT vs ATH-MSR7

Hello, I’ve got a bunch of questions for y’all headphone gurus. It will be much appreciated if you could answer some of them. Has anyone had experience with these? I was planning to buy the ATH-MSR7, but I’ve stumbled upon, what it seems like, his wireless brother - DSR7BT - are they even comparable sound-wise?
Will be there any significant difference if I’ll use them both wired? Or should I just get the MSR7 and then slap something like FiiO BTA10 on it if I’ll want my headset to be wireless?
Any advice would help, thanks :slight_smile:
