Don’t get the poly if you plan on using it outside the house. The only way to interface with it is with WiFi (which isn’t available outside), or with the built-in hotspot (which disconnects your phone from the internet). You could use your phone hotspot but the Mojo’s WiFi settings are very jank and also it eats battery like crazy. The only reasonable use for it outside is using Bluetooth, and this costs a lot for a Bluetooth dongle. At this point I’s rather just smash it through the USB.
Also worth mentioning is the WiFi only works in 2.4 GHz mode. I actually have that band turned off in my router because I live in an apartment building and that band is completely useless.
I bought the Poly second hand but I sold it again like two weeks later because I couldn’t get it to fit into my life. I don’t use it at home.
In wired mode, I just adore my Mojo2. Unfortunately, I have had zero success in getting Poly to work inside my home or outside. Perhaps there is someone here who can give me solid advice based on their own experience about how to get my Poly to work with blue tooth enabled Focal Bathys headphones. When these phones are wired to the Mojo2, the sound is so sweet it sends me into a state of rapture. However the months long frustration that I’ve experienced with Poly is bending me toward selling on the device.
To be clear, this is meant to be instructive rather than dismissive: there is no reason to wire the Focal Bathys to the Mojo2. The Focal Bathys digitizes any analogue audio being fed into it, and then runs that through its own DAC. As such, if you plug the Bathys into Mojo2, you are having Mojo2 convert the source stream to analogue, running it to the Bathys, which digitizes the analogue, runs it through its own DAC, and then you hear the sound. You’re doing an extra D-to-A and A-to-D, which definitionally is less accurate than sending the original digital stream to the Bathys.
For optimal sound, plug the Bathys into your phone (or whatever source) via USB-C, and turn on DAC mode. This is the best you’ll ever get out of the Bathys. Otherwise, just stream via bluetooth directly to the Bathys. By its nature, bluetooth is bandwidth limited to below full resolution digital, but it still sounds damn good if you value the convenience of wireless.
