ISOtunesFree True Wireless Earplug Earbuds, 22 dB Noise Reduction Rating, 21 Hour Battery, Noise Cancelling Mic, OSHA Compliant Bluetooth Hearing Protector (Matte Black)

Battery is alright .I put them on charge when I'm on breaks at work and charge them every nightI start work 630 and finish 1640Now the sound : it's really quiet so I suggest to anyone buying them to download a sound booster on your phone and have it just under the volume that it won't over work the speakers and distort the sound .I work in a wearhouse that plays radio 2 which is boring and full of moaners rather than music .so I see it as an investment to listen to your own music but we can only use these in there .Comfort :change the earbuds to what they give you to your preference. The ones on it raped my earhole .Overall its worth £60 most but it's better than bad radio station

The ear buds kept on coming out of my ears and this was just walking around the house, so wouldn't really work well on site ! Plus the changing port had a lot of movement .

getting used to it now but its unpleasant. only reason 4 stars. your ears will probably be fine i think its just a me problem.otherwise great, long battery.

I owned a pair of ISOtunes Pro for a couple of years. Used them daily with loud woodworking tools. They didn't survive a trip through the washing machine. I decided to replace them with ISOtunes free. The ISOTunes free are really comfortable to wear (I used the medium foam eartips previously, but I think the medium silicone eartips are more comfortable).They don't fall out my ears, the ISOtunes Pro cable used to occasionally pull one of them out my ears. That's not a problem any more.The sound is not top of the line, but there's enough range to cover rock, hip-hop and spoken podcasts while I'm working.They turn on automatically when you remove them from the case and I haven't had connectivity drops. I keep my phone in my pocket while I'm working. When the phone has been charging on a shelf in my workshop the bluetooth connection has been fine too.

Really the only product on the market for rated sound protection, the foam bits have a stupid plastic insert that screws into the headphones, which brake really easy, absolutely no point in them and they could have decreased production costs by using a standard fitting, but I guess they want you to form a monopoly on the foam bits.Overall they do the job and they fit alright, the sound is good and the battery life is fantastic.

Work well generally, comfortable and effective. The sound quality is OK but could be better. Bass isn't well defined and there is some hiss from left hand ear bud which I'm not sure if that's normal.

I had a similar issue to a few other people i have seen in comments on various websites including these comments The left earbud becomes unresponsive and the earbuds get stuck in a loop trying to pair with each other. This issue makes them unusable for about 4-5 hours until the battery drains enough on the left earbud to reset. The problem is the earbud gets stuck with a solid blue light and they cannot be turned off (manually by the button or replacing them into the charger). There is nothing in the manual about this permanent blue light. I wouldn't bother trying to contact the seller directly if you are in the UK as they do not respond and have no contact phone number to chase them.Sound quality and volume is also not great, a lot of white noise in the background when nothing is playing, they are also very very quiet even after turning the volume to max for bluetooth devices in android (including the trick with increasing the minimum on the max volume in volume settings and steps to root your phone).The good thing about them is they are quite effective at noise reduction when put in correctly but £99.99 for some earplugs is quite steep once the headphone stops working for hours on end.I would avoid these if you just want to listen to something whilst doing a lot of noisy work. I would buy some standard earbuds that fit under some ear protectors as this will work much better and probably come in cheaper.

I bought these ear plugs to use at work, I have found them comfortable to wear, have decent sound quality & a very good battery life.Sound quality during phone calls is also good.The only downside I have found is lack of any audio feedback for hearing conversations & occasionally the ear tip comes off & wedges in your ear , easy to get out so not a problem.Overall very good bluetooth earbuds.
