Reviews & Ratings for ISOtunes Sport OPMOD CALIBER True Wireless Tactical Earbuds With Bluetooth, 25 NRR — 84 reviews — Page 1

So far I'm very satisfied with these. They come with numerous ear bud sizes so you can find what works for you to find a comfortable fit. They hold a charge for a good amount of time and the sound reduction is better than some other ones I had prior to these. I would definitely recommend them.

Good battery life and hearing protection. I have 2 pairs that I use for about 4 hours each.

I bought these for my husband and he said they work perfectly as described!

I had been looking at a pair of these for a while and the sale made it too hard to pass up. They are well made and come with a variety of ear buds so you can find a perfect fit. They perform as advertised. I am very pleased with them and wish I had gotten them sooner.

Noise cancelling works well and is responsive. Great selection of ear tips, very comfortable. Pass through audio sounds a little artificial but is tolerable.

I wanted to love these… but they don’t charge in the case most of the time and half of the time one ear won’t get Bluetooth audio. I got them free with another purchase, but I’d be extra bent if I paid for them.

Very comfortable and so much easier than the "over ear" muffs. Ears don't get over heated and they don't get pushed out of place by a rifle stock.

Are my ears just that much different than most folks?! I do not understand how these "In the Ear" style buds (for shooting specifically) are generally rated so well. And these are no different than others I have tried, namely AXIL. They're all pretty much useless for the same reason! They all use the same style "foamy" tips that are all but impossible (for me: impossible!) to get seated deeply enough into the ear canal to adequately block the noise from a firearm discharging. Furthermore, these specifically do not function (turn on or off) accurately using the "Touch" system employed.
One slight positive for this brand is the ability to purchase different style replacements. I bought a five pack of the Isotunes Trilogy Universal replacement tips that fit this brand earbud. They are a bit longer and allow for more squeezing of the tip of the foam so as to get it (with a bit of work) further into the ear canal. Unfortunately, you still have to contend with the annoying "Touch" system of operation that doesn't work particularly well.
All in all, it's another waste of time and money for me. I'm not willing to spend the hundreds of dollars for a professionally fitted pair so, I will be content to use my electronic muffs from now on. For twenty bucks I will be happy to send anyone all three pairs (two AXILs and this one) of the "In Ear Buds" I have collected that will only serve to remind me of the money I have wasted on this style of hearing protection!

I received these with another purchase (no charge). They fit fine and they connect to bluetooth, but there is a constant noise (sounds like wind noise) that might be due to a noise cancellation feature. The only way to stop the noise is to turn the devices off, so I really don't see any use for them. They do fit under my earmuffs, but so do regular foam earplugs that weigh less.

These are not useful with the constant wind noise while they are on.

Received the ISOtunes, set up (charge, proper ear piece) and went to the range. The Bluetooth is awesome and the noise reduction works really good for hearing protection. If you want good protection and value…highly recommend
