    • Great Fit! All Day Battery! 2 levels of Sound Suppression!
Review Image by Topher Topher
Review Image by Topher Topher
I've been using these for two weeks now and I'm glad to find ear pro that can keep up! As a 3-gun shooter and match director I wanted ear pro that was secure, comfortable, wireless, could protect well enough with my competition rifle (with muzzle break), and play music/take phone calls while doing match setup and stage reset. These deliver!! I was also excited to discover they have two levels of impact noise suppression. Slower fire allows safe sound to still be heard, like shooting rifle steel at distance, while faster fire completely cuts out loud noise, like shooting a plate rack with my pistol. These react to the specific hearing needs of the situation and either limit noise in short bursts, or completely cut out all noise in continuous fire arrays. Recovery is fast in either case, so I can still hear what I need to, but avoid what I don't. Being in competition, I'm usually wearing ear pro for 6-12 hours at a time. Having a device that can protect when I'm the shooter, but also play music when I'm just resetting is a game changer. It's only been a few weeks but I've never had the battery die, even when used for 11 hours straight. Getting a good fit is not too bad, as long as I get these seated all the way into my ear. Inserting into my ear and then rotating down they seem to lock in place. I think some reviews about low volume and bad protection are probably not seating these as recommended. The max volume is almost too loud when inserted correctly, and 7 different sizes of ear tips made it easy to get a good sound seal. The touch pad took a little getting used to but I'm pretty good at it now. I can use Siri to make phone calls without getting my phone out. I wish they worked better with gloves, but that's another story. I also like that they automatically pair with my phone after the initial setup. Synopsis: Ultra secure, great audio quality, unique sound suppression, great price, and super long battery life make these a solid choice for those that shoot a lot! ... show more

    • Works for range use at a good price but there are better options
I've used a pair of Etymotic Gun Sport Pro in-ear hearing protection for several years and enjoyed their day-long comfort, but one broke as I was changing the foam earpiece. It came apart and pulled the very small wires off the solder. I fixed this but don't have full faith that it won't happen again. I purchased a set of the IsoTunes Caliber liking the idea of bluetooth functionality and rechargeable batteries, two features my Etymotic's didn't have. The Caliber ear pro is less expensive than the Etymotic by $100 or more. Not uncommon for same or better tech to get less expensive as time goes by. The Calibers can amplify ambient noise louder Than the Etymotics but is less sophisticated at the bottom end where you want just enough sound to carry on a conversation but no more. Even at the lowest setting the Calibers amplify too much. This is probably great for hunting but less useful at the range. I have enjoyed listening to to music at the range between sessions or when walking out to change targets and the rechargeable feature is great. As a test I made a phone call as well and that worked great. Two things I could not have done with my old ear pro. One possible negative for others is that I actually had to return the first set as the right earpiece didn't work at all out of the box. Amazon replaced it within 3 days of my request and the second set has worked as expected so far after two tips to the range. On balance I would think these were great and worthy of 4 or more stars if I hadn't owned the Etymotic's prior. The Caliber is not as good on the low amplification setting and heavier making them less comfortable. No complaints about them being uncomfortable just heavier and bulkier. I think this is a good buy and I'd buy another set with my experience so far. ... show more

    • Best that in this price range
The ISO tunes Sport calipers have really impressed me. I went from Walker headgear to these earbuds and they have worked fantastic for me. I’ve had them six months with my only problem being a lost the right earbud at the range contacted Iso tunes and they actually sent me a right sided earbud for free, by this customer service in this day and age were most companies you’d have to pay out the Wazoo, also the hearing amplification is a game changer you can hear a mouse piss on cotton 25 yards out! They are comfy for about 3-4 hours for me, and yes you can use at an indoor range. ... show more

    • OK at gunshot audio, inconsistent with dog barking or intermediate dB, more uncomfortable than Tozo
I wanted to like these, despite knowing they were semi-disposable because the batteries would stop holding a charge well after a few years. They fit more poorly than lower end CX Sennheisers or Tozo NC9s, they're more uncomfortable, the case is bulkier, and they don't noise cancel as well as either of the aforementioned for audio levels below that of an unsuppressed gunshot but above that of hearing damage (like dog barking). They also pickup and amplify unfortunate audio elements, cannot recommend at all for something like Metro / train riding where they'll actually make the ambient audio through a tunnel worse. ... show more
