Blockade earbud speakers are claimed to be the only EPA tested earbud speakers with an NRR.
They are rated at an NRR of 24, which is low compared to the NRR of 32 for the best disposable ear plugs.
The Blockade product seems very well made, as far as earbud speakers and related wiring goes.
They also feature a built-in volume controller, seen in the photo above, that does not require a battery.
The wires are coated with a flexible soft rubbery type of coating.
And, as you can see in the photo above, they are nicely attached to the controller with little flexible bosses to help prevent breaking at these critical bend points.
Both the speaker units and the controller have a nice look and feel and overall just seem very well made and have held up to my abuse so far.
The ear plug part of the speakers consists of the 3 silicone cones shown in the top photo above. They have a nice shape and seem to be tapered enough to hold in my ear canals.
The only problem with these is that they are long, compared to the other ear plugs in this review
The entire speaker/ear plug is 35 mm from tip to end, so they don’t fit inside every full-face helmet and they can be difficult to keep in the ear when the helmet is being pulled on the head.
Also, they may stick out enough to interfere with the lining in some helmets, so they’re best used with a helmet that has full ear pockets for speakers.
But if they remain in the ears, they do a decent job at reducing noise right away, although nowhere near as good as the disposable ear plugs referenced above.
The volume is limited to 91 dB to prevent hearing damage, but even 91 dB can be damaging, so be careful. The problem is that the music has to be pretty loud with these to drown out the wind noise once you get going.
I use the Blockade earbuds with a tiny MP3 player.
The plated connector plug fits an iPod (claimed; I don’t own one) and most other standard MP3 players I’ve tried. I can fit my tiny iRiver player in a top pocket in my shirt and run the cord up inside my jacket and it works fine
I put the player in my shirt pocket inside the jacket because this way the player remains on me and doesn’t interfere when I take the jacket off.
