Building on the original Guardian, the Plugfones Guardian Plus 29 dB 3.5mm Jack Earplugs/Earphones adds a longer cord, a straight jack, and a more capable feature set for anyone who needs hearing protection and audio in one device. Customer feedback shaped the redesign, moving the control panel closer to the jack for faster, easier access to play/pause, track skip, volume, and call functions. The IsoTalk noise isolating mic filters out background noise during calls so the person on the other end hears your voice clearly, not the environment around you, while factory-tuned speakers deliver full, accurate sound without losing key frequencies. Two plug options are included — a 27 NRR silicone pair and an industry-leading 29 NRR patented 3-tier foam pair — so you can choose the fit and protection level that suits the job. A hard case with a removable lid keeps everything protected during transport. For OSHA-regulated environments, the Guardian Plus is also available in a VL (Volume Limiting) configuration that caps output at 85 decibels, and multiple colorways are available.
