Review: Perfect for My Shop Use! - In my woodworking garage/shop got tired of wearing “muffs” with safety glasses and dust mask. Plus I have a wood turning helmet/respirator and a welding helmet that don’t allow the over ear protectors. When these were just released I pre-ordered them at ToolNut. I knew they are volume limited at 85dB but even in a quiet room there was no sound until the sound volume was at 1/2 and wasn’t very loud at all at full volume. Very disappointed so I had to pay shipping to return them to ToolNut. I tried the Isotunes Pro but didn’t like the cord. Also tried Powerbeats Pro and they sounded good but not enough sound isolation and they have a hook over the ear that I didn’t like. Later I noticed that desertcart was offering the IsoTunes FREE so I read the reviews at both desertcart and IsoTunes. I saw a lot of good reviews but also a couple that had my same complaint about very low volume I experienced. With desertcart Prime I had free returns so took a chance ordering another pair. Glad I did - the new pair was much louder. Even when using my Festool track saw or Domino jointer with a dust collector on the sound isolation is good enough that I don’t need to hit full volume to comfortably hear the music. Mentioning music - the sound on these is pretty good. Good base and balance. Very comparable to the PBP’s except the mid-range is little better on the PBP. This is my first set of Bluetooth headphones so didn’t know what to expect. Connection is quick and I can walk from the garage where my iPhone or iPad is into the kitchen 30-40 feet away and still hear the music. I’m getting good at inserting the ear tips and they are very comfortable. Battery life has been excellent so far. To be perfect for some reason I would like one or two more volume steps even though maximum is too loud to listen to for more than a couple minutes. Plus little better sound isolation would be nice. Only other thing I notice is when you stop the music you can hear some background “white” noise and it goes away after the headphones power down. I did some searching and found most if not all Bluetooth headphones do this. Update - ISOTunes had me send these back for testing of sound level. When I got them back they have quite a bit more volume. These are perfect for my application now. Great customer service!
Review: Manage your expectations - When I first got these they were a solid 1, maybe 2/5. The sound quality was not great and there was a low static background noise when they connected to a device. Also, they didn't fit well. So why 5/5 now? Because they work and do everything that they need to do. After figuring out how to actually put them in there is a noticeable sound reduction. Not a lot but it's there. They are okay for music but work best for listening to the radio/podcasts. That low static sound actually helps drown out the sounds that do get through like a white noise machine. They fit well under a pair of ear muffs and are not going to provide a pure silent listening experience, but that's the point. They have a Noise REDUCTION Rating, not a noise stopping ability. I mostly use these for landscaping, so mowers, weedeaters, chainsaws, ect. With a good pair of ear muffs it comfortable and I'm not blowing out my hearing. The connection does drop then immediately reconnect sometimes, but that seems to be normal for Bluetooth devices when they get knocked around. On a side note these are wonderful in an office full of people who are constantly talking. Really drowns out the sound and helps me focus without cranking up the volume.

## Questions & Answers

**Q: How do these compare to mainstream earbuds?**
A: FREE 2.0 is a safety product, first and foremost. It blocks 25 dB of sound coming into your ear from the environment and limits the audio output into your ear to 85 dB. Some non-safety headphones can have a maximum volume output between 100-115 dB.

**Q: What's the difference between noise-cancelling and noise-isolating?**
A: FREE 2.0 is a noise-isolating ear protector, meaning it blocks noise with a physical barrier (earplug) while wearing the product. Alternatively, noise-cancelling products produce an inverse sound wave to reduce noise while the product is turned on.

**Q: How do I get the best fit from the foam earplugs?**
A: Properly inserting your eartips provides better noise reduction and superior sound quality: Compress the foam eartip for 5 sec, pull up on your ear to open your ear canal, insert the plug into your ear and hold for 15 sec while the foam expands.

**Q: Are the silicone eartips the same for hearing protection?**
A: The eartips that come with ISOtunes earbuds have been tested for a Noise Reduction Rating (NRR). The FREE 2.0 has a NRR of 25 dB while using the foam eartips or a NRR of 22 dB while using the double flange silicone eartips that come with the product.

**Q: Can I use one earbud at a time?**
A: We always recommend using both earbuds for the best hearing protection and safety. However, the earbuds can work independently.

### ⭐⭐⭐⭐ Very high quality, but sadly the 85db limit is just not loud enough
*by S***Y on December 31, 2019*

Ok, I really wanted to be able to use these earbuds, but unfortunately they limit the sound of your audio just a little too much. The good: these are very well made, plenty of ear tip sizes to choose from. The noise canceling mics for phone calls work really well. And they do seem block out outside noise very well, works like when you're wearing just regular ear plugs. The bad: I bought these specifically for mowing the yard and other chores around the house using power equipment. When I tried them while using an echo hand held leaf blower, not the backpack kind, I couldn't get the volume of my podcast up loud enough to easily hear it. If the blower was just idling I could hear easily, but at full power, I could hear the podcast and even make out what was being said, but I was having to really strain and intently listen to make it out. That's just not going to work for me and it makes me sad because I loved everything else about these headphones. It was so close, if I could get just a few more dbs they'd be perfect. I gave them 4 stars because they did everything so well, and I think they may work some people who are working in a slightly less noisy environment. I wish they'd make a set without the volume limit for people who aren't worried about having to be osha compliant, if they did, I'd certainly buy them. Edit: I did find a pair that work perfectly for my needs and at half the price. Anyone like me looking for something to use while mowing I highly recommend them. I wrote a review about my experiences with these on that product's page. 2019 Upgraded, Anker Soundcore Liberty Neo True Wireless Earbuds, Pumping Bass, IPX7 Waterproof, Secure Fit, Bluetooth 5 Headphones, Stereo Calls, Noise Isolation, One Step Pairing, Sports, Work Out https://www.amazon.com/dp/B07MCGZK3B/ref=cm_sw_r_cp_api_i_R47jEbDXBCGAH
