Same generation

Both shipped in 2026. These are the same generation of hardware - nothing in the radio, the codecs or the noise cancelling separates them. The platform is level; the newer hardware shows up in convenience features instead - the TOZO Open X2 Pro adds Custom EQ and Water resistance IPX7 against IPX5.
