Pairing two or three of the devices differs somewhat from the generic device pairing procedure but it is still a simple procedure. The aerial popped out when the phone was opened. It was not actually functional, but market research showed people liked an aerial. Apart from that though, the rest of the casing, mounts and headsets look exactly the same as the previous BT multi-interphone sets we purchased before. They pair easily with everything I’ve tried, and they always reconnect automatically after powering off/on. More recently it branched into the manufacture of colour televisions.
Perhaps rider-to-pillion users will experience clarity at higher speeds given that both units would be closer together and would be filtering the same engine and road noise. The module is then slipped through and down into the cut-out of the clip and the 3.5 mm headset connector inserted. An alternate mounting method is to assemble all three pieces and slip the whole assembly on to the helmet. Their two tone look was more reminiscent of an earlier era. Radio phones A mobile phone is essentially a phone that uses radio waves rather than wires. Radio telephones were possible in the Second World War. Intercom range is excellent, right up there with the leaders, which includes the original Cellular Interphone and I suspect the new Interphone F4 system (review) recently evaluated by the Editor.
Each cell was adjacent to six other cells. The Motorola 3200 for example, looks very similar, although not identical, to the 8000 and 8500 series phones made in the 80s. It does work on the new system. The unit blew right off of my helmet and into the tall grass along the highway, never to be found. The original mobile phones from the 80s were referred to as bricks, because they were as big as a house brick. In the 80s, mobile phone users were rare a sight and the size of the handset made their users stand out in a crowd. Helmet audio quality is a very subjective thing but to my still discerning ears, the BT Multi-Interphone stereo headset speakers are very good, but not as good as the Chatterbox Xbi series headsets (review) or especially the AKE High-Sound speakers — my top choice.
