Review: ISOtunes Free 2.0 True Wireless Earbuds - Hearing Protection - I am required to wear hearing protection at my workplace. I have tried several types / brands of bluetooth enabled hearing protection. I like each type I have tried, but by far these are my favorite as there are no wires to catch on anything while I am working. Another set I have has the wire that goes around your neck, but I had a tendency to catch the wires at times due to working around machinery or with my hands etc when performing work duties. I have a set of ISOtunes earmuff style hearing protection with bluetooth. They have great sound, durability and range from your phone / bluetooth device, but due to the size I tend to bump into things when working on machinery. They are also much hotter in the summer weather (NO AC at work) and also tend to get somewhat uncomfortable over time as they are held on your head with a slight squeeze like pressure. This tends to push some on the ear lobes too. The ISOtunes Free 2.0 is so much better in terms of comfort. They are like using a typical push in type hearing protection plug and fit snug into the ear canal. There a re a variety of plug tips that come with the earbuds so just about anyone should be able to get the right fit. The range from your phone / bluetooth device with these is surprisingly good considering they are just a tiny earbud. I can walk about as far away with these from my phone as I can with the earmuff ISOtunes set I have (About 50 or so feet). I have read other reviews about some folks complaining the sound is not loud enough, but I have had no issues for the most part. I work in a noisy environment and can hear mine good enough to listen to podcasts. If you work in an area where the noise level is so loud you could not hear anything form these, it might be a wise idea to wear protective earmuff over top of these anyway to protect your hearing. If you are used to wearing earplug type hearing protection, you will enjoy the comfort of these as well as the sound quality. Sound is pretty good for such a tiny earbud. Battery life is better than expected too. I listen to podcasts, not music, so there may not be as much drain on the batteries when using them. They will get me through an 8 hour shift without having to place them into the charging case. The battery in the charging case has always lasted my a 5 day work week on a charge. This being my second ISOtunes bluetooth device, I will say I am impressed with their quality so far. I have had this set now for about 6 months and have not had any issues so far. I would definitely recommend these for anyone needing hearing protection and would like to be able to listen to music or podcasts from their phone / device.
Review: Must have for lawncare professionals - These by far have been the best ear protection and bluetooth ear buds I have purchased. Easy to pair with your phone. The auto powering function is a plus especially when wearing gloves. Looks bulky but are very light weight and fit within the ear canal. The silicone ear piece is comfortable and fits inside the ear nice and tight. Even on hot days, sweating they remained in my ear with little adjustment required. The sound deadening quality is great. Battery life is fantastic. Love the charging case too. The volume for music is perfect. The microphone is sensitive for phone conversations. If you're a landscaper, construction worker or just work in noisy environments. You can go about 20 ft from your bluetooth source before you begin to lose connectivity. I highly recommend these. We'll worth the cost.

## 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.

### ⭐⭐⭐⭐ Great earbuds and fantastic customer service.
*by A***T on January 11, 2020*

A couple of cons. 1) the foam tips that are the earplug part, often need to be replaced, and you have to touch them to get them in and out, which can lead to ear infections. 2) they have a flashing LED on the outside that blinks blue every five seconds while they're on and connected. You can't see it, but everyone else sure can. (I used slivers of electrical tape to cover them) 3) if I'm only using one, I either have volume control, or pause control, depending on which one I have turned on. A couple of huge positives: 1) unlike the pro, I can have only one turned on which improves my ability to hear my co-workers getting my attention. 2) the batteries last forever. I work 10 hour days. I stick them in the case at lunch, just because I take them out, and I've never seen them drop below 30%. 3) the sound quality is great. 4) the noise limiter is a bonus for me, I can't hurt my ears continuously turning them up. Voices are a bit quiet, but I can hear an audiobook running a huge automatic steel saw and a band saw. 5) they can activate my Google assistant, although it's a bit touchy because holding the button for a second longer turns them off. 6) they're super light and they're actually flush so they aren't crazy obvious. Edit: I had some trouble with one set of the plugs coming apart, and they sent me a pack of new ones. The customer service is fantastic!
