Design and features

The ISOtunes FREE wireless earplugs are not your standard earbuds. Designed to be used in noisy environments, they provide both hearing protection and wireless audio delivery. The ISOtunes FREE are ISOTunes’ most compact, lightweight product, weighing in at just 4.5 grams each.

Featuring ISOTunes True Wireless technology, these ultra-lightweight Bluetooth earplugs deliver great audio while protecting your hearing with a 22 dB noise reduction rating. They are also ANSI-certified as well as OSHA and NIOSH compliant and are designed such that you cannot damage your hearing at any sound level. They are also IP45 rated, meaning they are sweat, water, and dust resistant. The SafeMax 85dB volume limit means you’ll never turn them up too loud.

A 7+ hour battery life makes them last all-day with intermittent use, as well as an additional 14+ hours with the charging case. Recharging in just 1.5 hours, the ISOTunes FREE will be ready when you are. The case also recharges quickly, in only 2 hours.

The ISOtunes FREE wireless earplugs also have dual omnidirectional microphones with CVC background noise canceling, which means you can take calls in loud environments using one or both earplugs. The noise rejection technology rejects steady background noise such as a mower, drill, vacuum, and other steady-state noise products.

I found the audio quality just fabulous. Unlike other Bluetooth products, I did not experience any sync problems with the audio being offset from the video playback. As for noise protection, wow. I’ve used earplugs quite a bit in the past when I was working on aircraft, and these are just a pleasure to use.

ISOTunes includes three pairs of silicone double flange eartips, and three pairs of silicone double flange eartips – each a different size. This ensures that you will get the perfect fit. They are comfortable over long periods.

As for the call quality, my son said my audio actually sounded better than the Apple Airpods. The high fidelity aptX audio delivers rich tenor and deep bass.

What I like

  • Noise Protection
  • Great audio quality
  • A one year guarantee against defects in material and workmanship
  • 30-day money-back guarantee

What I’d change

  • Nothing I can think of

Final thoughts

I’ve been skeptical of most Bluetooth devices, having had quite a few that did not perform consistently well. The ISOTunes FREE earplugs have restored my faith that at least some companies produce great products. Being able to use them in noisy environments like when I’m working with power equipment is a bonus. Well done ISOTunes, well done.

  2. Are you using them with an Apple phone? I was under the impression (perhaps wrongly) that Apple phones do not use the bluetooth AptX protocol. Perhaps I’m wrong? Or perhaps you’re not using these things with an Apple phone?

    1. Yes, I have an iPhone 7 Plus. I don’t believe the iPhone uses AptX, so it just defaults to regular Bluetooth.
