Well worth the price
These headphones are well worth their cost. These are admittedly the only pair of open ear headphones that I currently own (though I own many pairs of different types and brands), but I am also aware of the price of most big name brands of open ear headphones on the market and these are significantly cheaper than most of what you'll find out there. Now that being the case I don't think you should be expecting the sound quality to be equal to that of say a $300 pair, but for the price they hold their own. The sound quality is not amazing, but it's pretty good and the bass is decent (better than I expected). Also, though I presume this is the case more or less for all open ear headphones, I find the way they sit on your ear to be very comfortable. They don't lead to discomfort with prolonged use in the same way that earbuds do or even over the ear studio headphones. I have yet to find myself aching to take a break from them. Though to be fair I haven't worn them for more than 4 hours in a single sitting yet. I think the other qualities of the headphones is where they really hold their weight. I haven't been able to test the 10 hour battery life yet, but I have yet to have the headphones die on me with many uses of 1-5ish hours at a time and I have yet to charge the case since purchasing. The battery of the case itself is impressive. It automatically charges the headphones when they are placed inside and they fit quite nicely into their individual spots with a magnetic hold that keeps them firm in place so they don't move around. The case itself doesn't scream high quality, but it also doesn't feel low quality. The headphones have touch functions that are fairly standard, but I find the sensitivity of the touch functions to be in the Goldilocks zone. On many headphones the touch can be way too sensitive and doing something as simple as adjusting the headphone can trigger a function like skipping a song which can be quite frustrating. At the same time if a touch isn't sensitive enough it can be almost as equally frustrating so I appreciate the balance with these. In terms of connectivity, the description I think undersells the headphones' capability. It claims a range of 10m, but I put them to the test and they can definitely exceed 10 meters and handle barriers such as walls and floors (and even a combination of both) without issue. They connect to my phone automatically (after the initial set up) when I take them out of the case and without much delay which gives them a nice ease of use. And finally, they do a pretty good job with phone calls as well. The mics have pretty good sound quality and pick up your voice well and the noise cancelling does a pretty good job of filtering out background noises when you're talking. Overall, if you're looking for a pair of over the ear headphones, but don't want to break the bank, I think these are an excellent choice. They're a solid bang for your buck.

Nice ear pieces
Quick to pair once you take the sticker covering the contacts where it connects to the charging case. Putting them in the case, closing the case, opening the case, actually turns them off and on, resetting the earpieces if they are in some confused mode. Which is kinda cool, makes it easy. They automatically pair to each other, and the right earpiece works without the left earpiece having to be used, so thats nice too. The only thing I wish it had was dual pairing, so I can have my laptop and phone connected at the same time. This set does not have that, the company does make a model that does that, though I don't have that one. For most users, this bluetooth will work fine. you can hear, without having to pull the ear buds off the ear. no, its not noise cancelling, because you don't have the ear plug in the ear which I can't do much anyway as the humidity is so high here, and body heat just isn't conducive to wearing ear pieces all day. For daily all day wear they are a win for me. Sound quality for music is nice, my callers hear me without me sounding distorted. It does require the app to pair to your phone, and you can tweak some of the settings to make the experience a bit nicer than a generic setup. Give it a try, I think you'll be happy you did. They are reasonably priced, and keep their charge for a very long time.

A Bearded Review - Truefree O1 Open Ear Headphones
As with any set of audio products, audio quality is one of the most important considerations. For the most part, everything else is secondary or at close to equal value depending on your preference. With that, here is my review of the Truefree O1 Open Ear Headphones. In the Hands and on the Ears The case is rather large, but light. Considering the size of the headphones themselves, this is expected. Allowing another of a smaller stature to use them, they liked that these would be easy to find in their small backpack or purse. When I tried them on, for someone with medium-sized ears, they fit snug and do not move if I jerk my head around. These sit around the ear lobe and over your ear canal (not in it). This provides a unique listening experience in that you can hear both what is being projected through the speakers as well as the sounds around you. Placing these on the smaller stature person with smaller ears, these were still comfortable and did not manage to come lose when jerking around. My only worry is if someone with large ears were to keep these on for an extended period of time would feel a little worn out after a while. Build Quality These ear phones are pretty solid. Their ends are plastic and the part connecting the ends is like silicon and adjusts with the size of the ears pretty easily. The case seems to be a thin plastic, however. I worry that it might not stand up to a lot of wear and tear if stored in a more open environment for a long period of time. As long as you keep track of them and secure them properly, the ear phones and the case should last for a long time. Audio Quality These use the LDAC HD Audio codec for high definition audio. Otherwise, these will connect to AAC and SBC. LDAC is a great codec if you want clear audio from your music and other higher definition audio sources. The caveat to this codec is the latency. In my testing I was seeing latency around 200-250ms. This means that if you are playing a game or watching videos, you will see roughly a 1/4 second delay from when actions happen or when people speak. I saw this with Diablo Immortal as well as on Youtube. With Game Mode on, the latency was slightly better, maybe 150ms, but it was still noticeable. Call Quality Calling with these was a breeze. I could clearly hear the other person and they informed they could hear me clearly. This worked in both in a loud and a quiet environment. Touch Controls and Software In my experience with the Truefree Android software running on Android 14, the controls worked, however they seemed delayed. Single tapping to increase or decrease volume worked ok, but the double tap to play and pause seemed to have a longer delay. I believe it might have to do with the audible prompts when you double tap. This happened with each double tap. The software… seems thrown together, to be frank. There are several inconsistencies with the language. For instance some parts say "click" and others "blows". Some wording is capitalized and others not. When I tried to configure the ear phones tap actions, they stayed with the defaults. None of the customized taps seemed to save. The EQ settings appeared to work well enough. The Adaptive setting was interesting. At first it appeared to not work, then I realized it was testing for each of the tones to see what you could, or could not hear. After tapping for each one I did hear, it created an EQ profile for me. Personally, I kept with my custom "V" EQ setting. Conclusion Overall, these are pretty good. The comfort of the set along with the LDAC audio is a good combination, so as long as latency isn't a concern. Listening to audiobooks, music, and other non-video or game media works out great for these. If you can get around the software caveats, this is a good set for your workout or walk in the park.

Great sound, good battery life. I believe the battery case is 800mah while others are 300-400. Only thing some people might not like is the case is on the big side but personally I like it. I also love how comfortable they are even with glasses 🕶️

I have a pair of bone conduction headphones to use for outdoor activities and found that although they allowed me to be more aware of things happening around me they gave me headaches with prolonged use. Decided to give these Truefree open ear headphones a try and came way surprised by how well they work. Since they don't vibrate against my head I no longer have headaches when wearing them for hours at a time. Pairing was easy, just make sure you remove the plastic covering the connector on the headphones first, plug them back into the case, and then press the button on the case to start the pairing process. I had no issues pairing them to my Apple iPad mini and my iPhone SE. Only caveat is you need to disconnect the headphones from one device and then connect with the other...it doesn't switch as seamlessly as Airpods but that's to be expected I guess. Sound quality is decent...mids/highs are good, lows are adequate but not booming. Because they are open ear don't expect much noise cancelling. The capacitive buttons on each side work well after you learn how to use them and get used to it. The case is quite large but it holds the headphones firmly in place. I've used the headphones for 3 days now for 2-3 hours per day and I'm still on the original charge from out of the box so the battery life seems good. Overall i would recommend these headphones if you need to be aware of your surroundings outside or home. Build quality is excellent, they're comfortable, battery life is good, and the price is really good.

The first pair I received stopped working about 4 weeks after purchasing. But I contacted support and they were incredibly responsive and helpful and remedied the situation immediately. I have now been using my replacement set for months. I am completely satisfied with my purchase. The quality is probably even better than the value for money.
