Are You Serious About Protecting Your Hearing?

NOTE: Due to the personal nature of earplugs, they are not returnable.

With the Etymotic Research Music Pro electronic earplugs, you'll experience natural-sounding hearing protection that can also help you hear low-level sounds. They're perfect for music teachers, performers, FOH crews, and even audience members. The Music Pro earplugs let you select between 9dB and 15dB of active attenuation, but it doesn't kick in until sound levels begin approaching uncomfortable levels. Until that point you'll hear everything clearly and intelligibly, which means you'll barely know you're wearing earplugs when you choose the Music Pro electronic earplugs.

Etymotic Research Music Pro Electronic Earplugs at a Glance:
  • Smart protection for your hearing, with optional sound enhancement
  • Zinc-air batteries give you long-lasting active attenuation
  • Comprehensive accessory set helps you get the best performance
Smart protection for your hearing, with optional sound enhancement

Because the Etymotic Research Music Pro electronic earplugs don't start attenuating sound until levels reach 70-75dB, you can hold conversations with ease without removing your earplugs. In fact, in the 9dB setting, sounds below the threshold are boosted by 6dB, further enhancing clarity. And because the active attenuation is a gradual transition, you won't hear disconcerting level flutters as it turns on and off. However, sharp, transient noise spikes are attenuated immediately. The overall experience is more like turning the volume down on the world, as opposed to wearing muffling earplugs.

Zinc-air batteries give you long-lasting active attenuation

The active attenuation in the Music Pro electronic earplugs comes courtesy of zinc-air batteries. These little batteries provide about 300 hours of life, which gives you about 2-3 weeks of everyday use. And because zinc-air batteries are not damaging to the environment, you don't have to worry about separately recycling these batteries when you need to replace them.

Comprehensive accessory set helps you get the best performance

You get everything with the Music Pro earplugs for dependable, professional use. In all, you'll get extra replacement eartips, a flexible and handy neck cord, replacement filters and a tool for replacing them, a cleaning tool, a test set of batteries (#10 zinc air), and a protective case. If your profession puts you in noisy environments on a regular basis, the Music Pro electronic earplugs are the professional way to protect your hearing.

Etymotic Research Music Pro Electronic Earplugs Features:
  • Electronic earplugs with selectable 9dB or 15dB of attenuation
  • Softer sounds are boosted by 6dB in the 9dB-attenuation setting for greater clarity
  • Attenuation starts at 70-75dB, which means you can hold a normal conversation without removing them
  • Perfect for music teachers, performers, and audience members
  • Also ideal for construction work, factory environments, and music stores
  • Complete accessory set included
  • Up to 300 hours of battery life, using replaceable #10 zinc-air batteries
  • "Impact" sound protection provides instantaneous attenuation for sharp, transient sounds

Reviews

WORKS
These work well for live performance. I play drums for a power blues/classic rock trio. It can get fairly loud. I've used these for three gigs now, and I am pleased with the balanced sound that these let get to your ears. I occasionally get a weird sound out of a certain crash cymbal at high volume. I'm willing to trade that for being able to hear the next morning. The battery life is roughly 6 hours of performing at typical bar setting volume.

Etymotic Research Music Pro Electronic Earplugs
I have been using the passive Etymotic earplugs for years but got tired of removing them between sets, etc. The MP's are expensive, but I thought I'd give them a try anyway.

With the two settings, the position that gives the 6dB of gain produces an ambient sound that is more natural and closely matches what your ear hears without the earplugs installed. The other switch position gave a darker, more attenuated sound. In either setting, I am unable to detect when/if the sound level drops when the band cranks up. Everything just plays at the same comfortable level.

In either setting, the earplugs have a noticeable high pass curve. I am the bass player in my band and I also run the PA. On the lowest notes on the bass neck, I could hear the "note", but not hear the "boom". Because of this, I had to remove the earplugs to balance the bass guitar in the mix. If you are going to use these earplugs while running the FOH mix, you would have to do so as well, at least until your brain gets calibrated to the loss of super low bottom end.

One odd behavior from the earphones....they pick up some wind noise. I notice this as I run a floor fan during the gig, and the airflow over my ears causes the issue. I have to lower the fan angle to avoid it.

The jury is out on battery life still. As we gig on the weekends, the earplugs are sitting idle with the batteries removed. I'll see how long they last in the weekly use scenario.

For now....they operate as advertised. Very natural sounding, with no obvious indication when they kick in. To me, the price tag is worth being able to leave them in my ears the entire show.

A Worthwhile Investment in Hearing Protection
Just made an investment in a pair of these Etymotic Research Music Pro electronic earplugs. Really cool technology. I've always had trouble wearing earplugs at gigs because I couldn't hear anyone talk between songs, or at rehearsal for the same reason. Constantly pulling them out was a pain, and everyone trying to yell for me to hear made me feel like a problem child. These allow normal sound to pass until SPL reaches levels that can harm your hearing, then the circuitry kicks in and adds a -15 db reduction. There's also a mode where it will enhance very quite sound levels and then provide a -9 db reduction when needed. I've tried passive plugs, including some older ERs with -15 db filters. They work fine until the need comes up to hear normal sound levels, as described above.

First test: rehearsal and songwriting session with full drum kit and Mesa half-stack, full bass rig...in a living room. Not painfully loud, but enough to need protection.

It was a really good test because there was a lot of discussion between bursts of playing. I never once had trouble carrying on normal conversation and the music was attenuated to about the same volume as the conversation. Never heard any abrupt attenuation at all. Pretty seamless transition actually.

The only negative is that they cut the lows I heard quite a bit, but my old ER-15 passive filters did the same. However, it actually made the bass more prominent in the perceived mix.

I think I'll like these quite a lot. I have a significant hearing loss (both hereditary and self-inflicted), and I consider protecting what I have left to be a worthy investment. These will allow me to be protected in cases where I might remove my plugs in frustration otherwise.

They work great, especially for listening to live music.
They also work well for playing music, however they do lower the bas bass frequencies more than the high end frequencies. So, as a bass player, it makes me want to turn up the bass to hear it. But they are light years ahead of every other method of hearing protection I have tried.
Overall, if the bass came through a little bit more, they would be perfect.

Not quite there.....
These are a great concept, but they have a BIG flaw and that is clipping! Crackly distortion when they run out of headroom, which is often. I wanted to have something I could take to concerts that were just a *little* too loud, but they were unusable even for this. Also, they need a wind noise filter over the mic. Trying to play outside in front of a loud PA in windy conditions was maddening.
