Complete transmitter-and-receiver packages that work out of the box: Shure vocal systems from BLX through SLX-D and SLX-D+ with SM58, BETA 58 or Nexadyne capsules, Sennheiser handheld, lavalier and headset sets across the XSW, EW-D, EW-DX and G4 ranges, Audio Technica systems, and dual sets that run two transmitters into one receiver.

Pick the input first: handheld sets for vocals and passed-around Q&A duty, lavalier sets like the XSW1 ME2 and BLX14/CVL for presenters who need their hands free, headset sets like the XSW2 ME3 where the capsule must stay put on an active talker. Tier comes second. Entry ranges such as BLX and XSW cover straightforward single-room jobs; SLX-D, EW-D and EW-DX bring digital transmission, denser channel counts in crowded RF and rechargeable battery options for daily professional use. Dual systems are worth a hard look for conference and function work, since one receiver handling two transmitters halves the rack space and cabling. As always in wireless, confirm the band variant against anything you already own, and note that Channel 38 use in the UK requires an Ofcom Shared Licence.

Add spare capsules, batteries and chargers from the neighbouring subcategories to turn a set into a working kit.
