Review: I like these headphones. I think they are definitely worth the price. - I will acknowledge that while I own many pairs of different types and brands of headphones, these are only the second pair of open ear headphones that I have owned; the first being the truefree O1’s. I can’t speak on how these compare to other open ear headphones aside from its predecessor, but I can speak on the quality of the headphones on a general basis especially keeping in mind that many other brands and models of open ear headphones are multiple times the cost. As far as how they compare to the O1’s, I think the O2’s are a nice upgrade in quality and they are listed at essentially the same price. I say this because I thought the O1’s were well worth the price so in my opinion these headphones are absolutely worth the price. As far as sound quality goes, they’re pretty good from an overall perspective. Don’t expect them to sound like really expensive headphones because they’re not, but these headphones also won’t run you hundreds of dollars. The bass is actually a nice surprise on these. They obviously don’t quite compare to something along the lines of medium to high quality studio headphones in terms of bass, but for headphones of this size and type the bass is better than expected even in comparison to the O1’s. These headphones can also manage a pretty loud volume. As far as comfort goes these headphones are very comfortable to wear. Though this is presumably true for many open ear headphones, they don’t lead to discomfort with prolonged use like buds and studio headphones do. I have worn them for many hours on end and have never had issues with discomfort or aching. In comparison to the O1’s these fit much tighter to the ear and stay on much better. I can and have gone for runs in these headphones and never had issues with them falling out of my ears. I haven’t even encountered moments where they felt like they “might” fall out. While on the subject of running, I haven’t specifically tested the water resistance of the headphones, but I have used them for runs and working out and sweat has never caused any issues for them. I can’t say I’ve timed the headphones’ battery life, but I’ve used them many times for 4-6 hours a pop and they’ve never died on me. I’ve used them for longer than 6 hours with breaks in between where I popped them into their case until resuming use and have never had them die on me in those instances. For example, if I’m working a long day, but take a 45-minute break for lunch I’ll pop them in the case while eating and then finish out the rest of my work day without having any issues with the battery. That said they seem to charge pretty quickly from the case. And the case itself charges pretty quickly as well. The case has a solid battery. I can’t say I’ve kept an exact record of how many hours of charge (for the headphones) the case holds, but the claim of 22 hours seems accurate if not an undersell. It charges the headphones automatically when placed inside and holds them into their places magnetically nice and snug. The case itself feels nice and solid and has a sleek design to it though it’s nothing super fancy. One of the things I really like about these headphones is that they connect within seconds of the case simply being opened. By the time I even have them on my ears, they’ve long been connected. And while there doesn’t seem to be a claim about the Bluetooth’s connection range, I have tested them out and found them to reach over 60 feet through multiple walls, walls, objects, doors and even all this in addition to exterior masonry walls. So that said the Bluetooth connection on these headphones is very solid. As far as the mic goes you can definitely tell that you’re using headphones from the other end of a phone call (though I find this to be the case with essentially all my headphones), but the sound quality comes through clear. I also find the sensitivity of the touch functions to be very ideal. They are just the right balance of being responsive without being too sensitive so you don’t end up triggering functions when you’re simply trying to adjust them. I know I touched on a lot and I’m sure there are some aspects/functions of the headphones that I skipped over in reviewing, but at the end of the day my final opinion is this: If you’re looking for a reliable, comfortable pair of open ear headphones without wanting to spend a lot of money to go super-high quality then these are well worth the purchase.
Review: Great Value Proposition - I’ve owned a lot of ear buds and headphones. I have gravitated towards open ear design headphones as I like being able to hear the outside world while still being able to listen to music. I’ve owned a few Truefree models as I’ve found them to be a very good value for the price. Prior to these earbuds I owned the Truefree F1 open earphones and then to their latest F2 open ear headphones. These models are similar to the O2 except they have an ear hook and neckband design that connects the two buds and provides a bit more secure fit and makes it harder to lose an earbud. For me that design serves a purpose if I were to go hiking, riding a bike, or similar activities. Where that design falls short the design of the O2 handles. If I’m working out and doing exercises where my head is on a bench or lying on the floor the neckband design of the F2 is the best as it hits the bench/floor and the buds move away from my ear. The O2 headphones work fine when I’m lying on a bench and doing exercises like a bench press. Concerning the O2, you’ll first be greeted with the case. The case is easily pocketable and I like the texture of it. It has a subtle grip to it and is anti-fingerprint. Onto the earbuds, these pair super fast. I have them connected to both my phone and laptop. I like how they seamlessly transfer from one to another. For example if I’m listening to music on my laptop and then get a phone call, the earbuds stop the music and I can have a conversation on my phone. When I hang up my call the earbuds pick up where they left off with the music on my laptop. Very nice. I also use these for Zoom calls and I’ve been told I sound fine on the other end of the video call. Since they don’t have the neckband like the F2, they are lighter – almost too light where I forget I’m wearing them. I’m not an audiophile where I only listen to FLAC audio files. If I was I wouldn’t consider any Bluetooth earbuds. Since I’m not, I’m very happy with the sound these put out. I listen to a wide range of music from classical to country to rap to rock. When changing listening habits I do change the equalizer to match the music and you can hear the difference in the various equalizer settings. While I’ve just got these I cannot speak to longevity but I can say I’ve had their earlier models and they still work great and the battery still lasts a long time. TrueFree F1 purchased 9/2022 Truefree F2 purchased 3/2024 The App Truefree has an app you can install. The app is nice as it will handle any firmware updates but has a few other features. There’s an equalizer that has 8 presets plus a fully customizable one and on top of all that they have an adaptive equalizer. The adaptive equalizer requires you to take a quick 2 minute audio test and then it adjusts the equalizer to your hearing which I’ve found to be very good. Lastly the app has a white noise library which is kind of neat. Overall when I consider the price, I’m very impressed with these. I’ve found TrueFree to be very consistent (otherwise I wouldn’t have purchased so many earlier models) in providing an exceptional value for the money which is why it’s easy for me to give them 5 stars. If you get these be sure to download the app.

### ⭐⭐⭐⭐ Great Successors to the O series
*by K***H on January 12, 2025*

They impressed me overall with their audio quality and design, although there are a few areas that could use improvement. The clarity during phone calls is outstanding, as if they're right next to you. The audio only needs 20-30% to fully enjoy in quiet places and 50%+ for public. Also, when you open the case, the power on announcement is a set volume which might get to you at first because it's a bit high and your audio won't play until you take them out the case so can't use them like a mini speakers. The earbuds sit great in my ears, with the speakers curved inside for better quality. The charging case has a smooth texture that feels nice, although it's a bit slick and could easily slip from your hands. Battery life is amazing, offering 22 hours when utilizing the case, but I've had it last more than a week. It has the basic GYR color for battery life and red can last a couple days before they die completely. I do wish the touch controls were a bit more intuitive; they're only activate once audio is playing, which you get use to after a while. Additionally, a broader range of color options would be welcome, as the current orange neon and gray carbon design isn't my favorite but it grows on you. Nonetheless, these earbuds strike a solid balance between performance and comfort, making them a worthwhile investment for anyone seeking quality audio on the go.
