what's in the box

What is Tactical Sound Control? Can it be turned on/off?

TSC is a level-dependent technology that uses omni-directional microphones to allow safe sounds to actively pass through the product while blocking harmful gunshot noise. TSC volume can be turned up, down, or off from the touch sensor earbuds.

Can you use Bluetooth while using TSC? Do you have to use Bluetooth to be protected?

You can use both Bluetooth and TSC at the same time. Heat activated polyurethane foam ear tips block 25 dB of noise so your hearing is always protected, even if you are not connected to Bluetooth.

Will earmuffs fit over these earbuds?

The ISOtunes Sport CALIBER BT earbuds should fit flush with your ears allowing you to wear earmuffs over them comfortably.

Does the ambient sound come through both ears?

TSC volume for the CALIBER BT comes through both earbuds. When using TSC, the headphones are designed with separate left and right microphone channels to the corresponding ear to give you spatial and directional awareness.

Are the silicone eartips the same for hearing protection?

The eartips that come with ISOtunes Sport earbuds have been tested for a Noise Reduction Rating (NRR). The CALIBER BT has a NRR of 25 dB while using the foam or the silicone triple flange eartips that come with the product.

Great Fit! All Day Battery! 2 levels of Sound Suppression!
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!

4.0 out of 5 stars Buon rapporto qualità prezzo.
Reviewed in Italy on June 1, 2022
Pros:
1. Ottimo rapporto qualità prezzo
2. Personalizzabile con diverse misure auricolari in gomma piuma fornite
3. Confortevoli e leggeri specialmente col caldo
4. Resistenti a polvere e acqua
5. Batteria molto capacitiva

Cons:
1. Microfono non adeguato fa sentire molto il vento a meno che non si riduca totalmente il suono, a quel punto però sono come dei banalissimi tappi in schiuma.
2. In caso di uso Bluetooth con uno smartphone l’audio di chi riceve le telefonate risulta non ottimale. Anche l’audio musicale è inferiore in quanto a qualità rispetto ad EarPods con filo.
3. Abbattimento del suono non troppo efficace, specialmente in poligoni al chiuso o durante competizioni affollate. Si sentono amplificati i rumori generali e quando si spara il suono viene abbattuto regolarmente rimanendo però chiuso oltre il dovuto.
4. Riduzione del suono in aereo poco o per niente efficace in quanto bisogna agire come nel punto 1. Molto meglio una cuffia completa tipo “bose”.
5. Comandi touch poco o troppo reattivi.

Nel complesso un acquisto fattibile visto il prezzo di 179€ che a confronto con altri prodotti simili è attualmente la metà. Ovviamente una cuffia elettronica ha ben altra risposta in qualità e protezione ma un ingombro ed un comfort differente, specialmente con il caldo. Il vantaggio delle dimensioni ridotte è anche salutare per chi tende a togliersi le cuffie in gara in attesa del proprio turno, esponendosi a decibel di troppo, questi auricolari li metti su e quasi te li dimentichi per una giornata intera al poligono.

Reviewed in Canada on November 6, 2023
So i bought a pair of these after reading through the good reviews and bad about some ppl having issues with them. I figured that sometimes ppl have a bad experience with a product and I was willing to give them a try with those who really liked them. So I ordered a pair, they were here the next day, just before the weekend and I could take them to the range.
I quickly opened up the box and liked what I saw. Decent looking charging case and well made buds. So I put the ear buds in the charger and noticed right away that one light started blinking and the other nothing. So I figured they needed more charging, put them in the charging case and went about my business for a few hours.
I came back an hour later and still the same thing, they won't turn on. Well damn, i guess it was my turn to have the problem others online here warning me about. So ok i decided after doing a lot of online research because there is nothing in the little manual or online manuals that explain what the lights are supposed to do I figure I have to send these back. Thats when I got made and pissed off.
I started putting the stuff back into the box and what do I notice that i hadn't noticed before, packing tape on the box. So here is what I am thinking, someone else bought these earbuds, had problems with them and sent them back. Someone has packaged them back up with the packing tape shown in the photos and shipped them to me. WFT? really not a happy camper here.
These are being sent back to Amazon tomorrow and i am not sure I will replace them with the same product. I did call the rep for these in Ontario and got a really nice woman on the phone who explained that if i had bought them directly from them they would have been new ones from an unopened box. After speaking with her I would consider buying another pair however i think I have lost faith in the product and am wondering ok if I buy a another pair of these how long will the batteires really last?
Be warned.
