Similarly the Daptor 2 (approx $160) can easily be interfaced with a cell phone, but requires a mix-minus configuration to facilitate communication with the other end of the call. This box doesn’t even provide a jack for an earphone/mic, and only a line-level in, so it’s best as a utility box to send audio from a remote location back to a studio, or connected to a mixer.
There are Bluetooth interfaces as well that will pair with a cell phone without cables, much like an earpiece will, but the additional stage of wireless communication strikes me as adding even more sonic compromise, so they may be fine for convenience, but perhaps not for critical audio.
There’s another problem with the cell phone taps: mobile phones often create electromagnetic interference on recording equipment. Some phones and networks are more problematic than others, but an active phone, even with the ringer turned off, can create bursts of noise that are picked up by microphones or cables. The usual solution is to turn off any nearby cell phones, as in power them completely down, but you obviously can’t do that if you’re using one as part of your recording chain. So, proceed with caution.
