Sennheiser MKE 2 vs Rode M2: which should I buy?

The Sennheiser MKE 2 is explicitly listed as an omnidirectional condenser lavalier with an XLR connector. That makes it the clearer choice for a discreet, hands-free setup. Its listed best new price is £324.

The Rode M2 is listed as a condenser microphone at £81. It is substantially cheaper, but the supplied details do not establish its pickup pattern, connector or intended application, so this is not enough information to treat it as a direct substitute.

My practical advice: choose the format your job needs, rather than assuming the dearer mic will sound better. If you need a lavalier, go for the MKE 2; otherwise, check the M2’s full specifications and both microphones’ power requirements against your setup before buying.
