Thanks for the comparison. I have been unhappy with FiiO’s app implementation in the past. So wanting to try this product first.

There are actually a lot more products that offer similar features not limited to the FiiO bt2. I had the chance the try the bt2 which has longer playback hours and a similar set of features, objectively speaking its build quality is not as premium as the Shanling so as the output level. You can pick out more power/ density is in the mid-bass on the mw200 which sounds overall fuller, bt2 is cleaner and packs in less punching power but that gives it more playback time.

The price of the mw200 is closer to the BTR5 too that is why I associate them. Despite that fact, if you don’t need NFC, better build, and uses more sensitive IEM with good bass, the bt2 could be a more affordable option with longer playback hours.

I have the Fiio, and I see that as the most direct competitor in terms of form factor and features. I was hoping for a bit of a comparison between the two. Seems like an incomplete review.
