Perfect for noisy office environments
I was pleased to see the new and improved version have a DB rating!  But a word of caution:  Once you insert the speaker into the tip, they do NOT fall out.  In fact, I had a difficult time switching from the foam back to the silicone tip.  I ended up tearing the foam.  These are not made to switch back and forth.  I did have to use considerable force to remove the foam tip.  Be sure to grab the rubber insert rather than the foam when removing.<br /><br />I still give these a 5.  These are great ear plugs, and do exactly what I need them to do.  They eliminate normal noise from my cubical neighbors, and greatly reduce it when they are especially loud.<br /><br />Just be careful when you switch FROM the foam tips.<br /><br />Updated:  June 6, 2016 - Don't last long<br />I love these, but the price is getting to be too much.  I have had to replace my set about every 2 months.  Pic 1 shows the rubber ear part coming off, while this is necessary to change between tip types, it is too loose, and gets left behind in my ear.  Pic 2 caused me to update this review.  The plastic base section separated and is only held in by two tiny wires.  At $30 per set, comes to $180 per year.<br /><br />This is so disappointing, they cut 95% of the sound and distractions outside my cubicle.  These also fit well in my ears, I have an odd shaped ear canal, and these fit into my ear well.  I just can't afford the price.
