- AO Safety Blockade Ear Buds
- Brand: AO Safety | Category: Safety Equipment

Folks who use Work Tunes protective earmuffs, or the various clones, know how enjoyable listening to music or a podcast can be while working.
I like my Work Tunes enough to have replaced them several times as I’ve broken them. Nowadays, I NEVER listen to the radio. My IPod, with over 1000 songs, and 50-100 hours of podcasts on a typical day, has completely replaced radio in my life. Like TiVO has changed my TV viewing, my IPod has made listening to the radio almost painful. <g>
The downsides of the Work Tunes muffs are they are much heavier than my non-radio AO muffs, they have less noise attenuation than standard muffs and plugs, and they’re HOT to wear in the summer time. Understand this… I’m not using “hot” in the same context Paris Hilton would!
A few weeks ago, I decided to Google around and see if anyone had manufactured some sort of earbud with protective qualities. Bingo! Several appeared. I chose the AO Safety version based on my past experience with AO glasses, ear plugs, and various forms of ear muffs.
Anyone who counts a portable listening device as a constant work companion NEEDS THESE OUTSTANDING EAR BUDS! AO claims an NRR of 24, and they compare favorably with other devices I have that rate a 24 or 25. Work Tunes claim a 22, and I think the Blockades are quieter. These suckers are incredibly light, they seem durable, and are so comfortable, I forget I’m wearing them. They’re decent looking, so you won’t look ridiculous wearing them at the gym or beach. I think the sound quality is better than stock Apple buds, but not as good as my $75, no-protective buds. In other words, very good!
My kit included two extra sets of silicone plugs (all six plugs are the same size, unlike many non-protective buds), a drawstring carrying bag, and a handy inline volume control. I paid $39 @ Amazon, and have started to see them in big-box stores and safety dealers.
Highly recommended for those who listen and work!
UPDATE 05/11/2009—- With almost daily use, I still love these things and they’re holding up well! Over time, I’ve realized they are far quieter than the Worktunes muffs, lighter and cooler, and much more compatiible with safety glasses and face shields. If the seals get dirty, I’ve been removing them from the electronic portion and dunking them in denatured alcohol. I’m still using the first set of seals, the alcohol and use have had no ill effects. I’m now using an iPhone instead of the iPod.

CPB,
Good review. I have been looking for something like this since I got my new Air Pro.

Barry, you saved me some money and maximized domestic harmony here (have though about Work Tunes). It might stop my wife from coming out to tone down the driving rhythms emanating from the shop.

These are good, but I still prefer Sens Gard

Mott,
I like Sens Gard too, but I don’t know of a version that allows electronic listening. On airport ramps, I use SG’s or EAR foam plugs, as a taxiing jet can make a wood shop sound like a library.

I have been meaning to review mine for a long time, I’ll now just comment on yours. I wanted good sound and protection, and these are the best I have seen so far. They are expensive, but sound quality is great and they are very good at sound attenuation. I use the cones which are 35db, the foam is better, but I thought it would be a problem in a wood shop. I have to be careful, I cannot hear some of my equipment running with them on.

Marco,
$300? You aren’t kidding they’re expensive. <g> On the other hand, my hearing is important to me enough that I spent $900+ on an active noise canceling flight headset.
Be aware that a 24 NRR does not mean 24 db. Interestingly enough, Etymotic does not provide an EPA NRR.
The packaging from the Blockades states these attenuation specs:
125 – 35.2 dB
250 – 35.9
500 – 37.5
1k – 35.4
2k – 33.8
3.15k – 38.6
4k – 36.4
6.3k – 40
8k – 43 dB
Somehow, this all adds up to an EPA NRR of 24.
Have you tried a set of the $40 versions and compared them? It would be interesting… I’m sure yours have insane sound quality, as they’re built to mixing reference standards. I’d wonder if my IPod can actually put out reference quality sound? I wish those were available back when I was a working sound mixer, especially at the stage monitor desk, as they look extremely comfortable.

I read your review right after you posted it. I have been thinking about getting something more effective than the standard ear buds that came with my MP3 player for a while and your review spurred me to action. I did my usual net research and found enough about several products to satisfy myself that these were the way to go so I ordered a pair.
Thanks for the help.

I’ve been playing music professionally for some years, I have some experience with recording. I can say the Etymotic are great quality. The reason I got them, is they seemed to have the best protection when I bought them 3 years ago. I had trouble with one tip breaking, (my fault) and they fixed at no charge.
Guess we can call them the Lie-Nielsen of ear bud manufacturers!

Just a follow up for anyone that is interested. I recieved my Blockade earbuds this morning and used them all day while working in the shop. Amazing is all I can say. A product that really delivers and a price I can afford. One minor concern is longevity in the shop environment. These are very lightweight and although the production appears to be of excellent quality, the materials don’t appear to be very rugged. That said, these were a real find. Thanks for the review.
