Sync Stereo Earmuffs


 Optimizing acoustical earcup design, volume management technology, and personal hearing protection, Honeywell Safety Products introduces Sync™, the next generation of stereo earmuffs  from Howard Leight®. Sync delivers the proper levels of hearing protection in hazardous noise environments with high-fidelity stereo sound from users’ personal portable audio MP3 players. “Most stereo earmuffs used in industry today provide a moderate level of hearing protection, but often sacrifice the sound quality of the attached MP3 players – which can work to discourage their use,” said Renee S. Bessette, COHC, Global Brand Manager, Howard Leight / Honeywell Safety Products. “In contrast, Sync stereo earmuffs optimize new designs and technologies that provide both hearing protection and true listening enjoyment. Sync entices usage – to deliver protection from noise-induced hearing loss  (NIHL) on the job or at home.”

Sync stereo earmuffs feature:

  • Protection from Hazardous Noise - With an NRR 25, Sync provides ideal, consistent hearing protection  and ensures appropriate attenuation in most industrial environments. Sync’s Volume Management Technology™ manages sound levels reaching the user’s ear to a safe level.
  • Plug In and Go – There are no volume knobs or power switches to coordinate nor batteries to replace. Ease-of-use is enhanced by maintaining volume and power control through the MP3 device. Users simply plug MP3 players and personal audio devices and listen.
  • Personal Listening – Sync can be used with a user’s own MP3 player, mobile phone and other personal audio devices, ideal for use at work or at home. Its technologically advanced acoustical bass chamber enhances bass sounds that are typically sacrificed in industrial stereo earmuffs.
  • Cool, Modern Style - Sync’s earcup design is DJ-inspired, and the sound quality is on par with other professional audio headphones. Sync’s stylish design easily surpasses other industrial earmuffs. Both comfort and fit are ensured by its padded diamond-patterned headband and its reinforced forkslides that keep it in place when worn.
