So far good! More comfortable than the other brands that I own!
Great to hear! Thanks for taking the time to leave a review.
The overall look and build quality looked good and they functioned well. The fit was just too tight with no way to adjust. Had to return. Will try the Advance BT. ISOtunes customer service was great. Would recommend to people with smaller heads.
Thank you for being an ISOtunes customer and for taking the time to post a product and service review. Your feedback is appreciated.
These headphones are amazing, especially considering the price point.
Thank you for taking the time to post a review on the ISOtunes DEFY BT earmuffs. Your positive feedback is appreciated.
Good except it seems to either the battery does not last very long or it auto-shuts off while I'm using it. I was at a week-long, whole-day shooting event and that happened a couple of times.
Thank you for your purchase and we appreciate you taking the time to leave a review about your DEFY BT earmuffs. The earmuffs are designed with a battery-saving feature and will automatically shut off after 4 hours of use. When this happens simply power the earmuffs back on. We apologize if this has caused any inconvenience.
It’s a great device.
The product is excellent.
Love it! Thank you for letting us know - We appreciate your review.
May need some improvement.
I do give this product a 5⭐️ review, the sound quality is really good and on the ears they are decently confortable, overall, the piece that touches the top of the head may need some padding/sponge/cloth or something, after some time using them the top of the head hurts and they become uncomfortable since the plastic is straight resting on the head. Anyways, the sound quality is good and if they solve the problem with the padding and will definitely buy them again. PS. Battery life with AAA and the charging battery is great.

So far verity Good in the shop, soon will be checking out on the Range.
Thank you for posting your review of the product. Your feedback is appreciated.
Very comfortable, I wore them for several hours yesterday. Bluetooth sound quality was really good, as was the amplified sound. I purchased these on the recommendation of HRFunk.
Thank you for using our product and for sharing your experience. Your feedback is appreciated.
Great Product, Good Sound. One issue.
I bought two of these so it would be easier to talk to my father when he is at the range with me and because after much research, I found these to have the fastest reaction time to noise. I will say I had the earbud style prior to this, which worked great, but no matter what ear piece I used or how I inserted them, they'd fall out. The headset was the clear option. I have found that they do a great job cutting out the gunfire at the range, and the bluetooth sound is pretty solid. I have tried out the Sig Sauer and two other brands from friends at the range; while comparable, these have more comfort and feel sturdier. However, on 3 or 4 different occasions (occurring for both of us at separate times), had the experience of the sound of gunfire NOT being canceled out, but in-fact amplified as if it was regular conversation. Luckily for us, when this did happen, we were only using .22s or 9mm at the time. I believe this may be more on how the sound is reflected and reverberated in our surroundings over a defect in the headset. Together, at the time of writing this, we have collectively used these headsets approximately 30 to 40 hours and if necessary I could replace them with the same should anything happen to them.
Thank you for sharing a bit about your experience - We appreciate it your review. We're happy to hear that your experience has generally been positive. Should you have any further questions or concerns involving the gun noise suppression vs. amplification, please don't hesitate to reach out to us - Our team would be more than happy to troubleshoot.
Good BT sound and good noise suppression
Very good sound. The volume and power buttons could use raised symbol to help with locating to buttons while wearing the headphones.
