Sort of. The SMH5 can pair with up to three other headsets, but communication is only 1-to-1, whereas the SMH10 can do a 4-way 'conference call'. The SMH5 work the way the original SMH10 did, with regards to intercom between headsets.
Multi-pairing with regards to mobile phones, lets you connect your headset to two mobile phones at once.
