truefreeO1 Open Ear Headphones Bluetooth 5.3 Wireless Open Ear Earbuds with 16.2mm Driver, Immersive Stereo Sound, Noise-Cancellation Mic for Clear Calls, 45H Playtime, for Sports Workout

The TRUEFREEE O1 Open Ear Headphones have amazing sound, long play and lightweight wear.I just got these and have been wearing them all day for the last week! They are light and easy to wear all day, they sound amazing, the continuous play lasts a LONG time, and the APP actually gives you useful options!I have many in-ear, over-the-ear and open-ear headphones. I like to sometimes have open-ear headphones so I can hear what is happening around me. I wanted a pair with longer play time than my 3-6 hour pair, and I wanted great sound. I read someone saying these had great sound and so here I am!The case is about 2.75” wide x 3.5” long x 1.25” thick. It is currently the largest case for any headphones I own…like a thick deck of cards. You get ~3 recharges off the case! The case recharges pretty quickly using USB-C (a separate 3” cable comes with the case).I opened the case and was greeted by three dots on the case indicating a full charge on the case, and each headphone had a tiny light. I pulled out the headphones and removed the protective tape on the charge ports and put them back in, in case they needed to charge.When I was ready to use them, I put them on and was very surprised how light and imperceptible they were to wear. I simply do not or barely feel that they are on. Beyond being comfortable, they are the lightest presence I have experienced in an over-the-ear headphone. I was not even sure if I had them on right the first time. But the left and right are clearly marked in the case and on each earphone.They easily synced with my phone, I did what I needed to do and then quickly synced them with my computer to watch a film. First, the music and sound quality is AMAZING. Not amazing for an open-ear headphone, but just amazing. Still, I could hear ambient noises, so wearing this while running water for dishes or vacuuming made them harder to hear. Volume is STRONG! So, I am happy at 20- 30% and have room to spare if surrounding sounds get louder.I think my first use of these lasted close to 11 or 12 hours before I was warned that the power was low! That is exactly what I was hoping for!As with most other headphones, they can pair to multiple devices and the one with sound takes over. In my case, the computer will override the phone. If I turn off “dual device connection” in the app, then it will only connect to one at a time. Which I find I prefer.I am also super happy that these are splash resistant. They are IPX4 (meaning that they are rated to offer protection against splashes of water) making them suitable for workouts, bathing, jacuzzi, or light rain.I am VERY happy with these and highly recommend them!Now, about the APP (See the photos):You do not need the app for normal headphone use. But the app allows you to see headphone specific charge state, personalize the EQ, personalize settings, etc.Also, FYI, when you open the APP it creates a new instance for itself in your Bluetooth settings (TRUEFREE O1_B…”), close the APP and that goes away. Occasionally, when I open the APP it has trouble identifying the headphones. I have not solved why yet. But the APP allows sending issues to tech support (under Help and Feedback) and also Firmware updates (in settings), so these little things may get addressed.It honestly took me 15 tries to get signed in to the app the first time and I know I am not alone, as others have asked what they are doing wrong in Amazon Questions. Once you get signed in the first time, you don’t need to do it again. Watch the video in Amazon Qs on how to get to the register screen. I think after selecting accept, I clicked “forgot” at the bottom and that is where the register option is. Enter email, enter a “letter only” password, click to get your code sent to your email. Enter the code, view the terms again and click Register. Try again if it does nothing. It will work after a few tries.The APP lets you see the charge level of each earphone (See Photo). Which I find useful sometimes when deciding if I should charge them and use a different pair when planning on doing some things.The APP offers many preset EQ to select from as well as offering a customizable and savable EQ option (See Photos). This makes me VERY happy, and I have been refining my own custom settings to suit my hearing!I love that I can DISABLE ALL TOUCH CONTROLS here (See Photo)! I have longer hair and, when wet, I accidentally stopped play or turned sound up or down. Disabling touch on demand is the solution.You can also toggle game mode and dual device connection in the APP (See Photo). There is also a place to customize the touch settings, but I have not used this yet.There is also a hearing test. This is very cool as it tests your hearing sensitivity across a spectrum of sound frequency types to personalize the EQ. I would love to learn more about the tweaks made based on my weird hearing!Additionally, under settings there is a library of relaxing sounds: “Relaxation Music Hall” (See Photo). These are actually quite nice recordings and I have used them to block out other sounds and even to fall asleep when my tinnitus was bugging me! They include a stream, rain, fireworks, walking on grass, birds, electro-pop dance tune, sheep, crickets, frogs, ocean, tennis, wind chimes, beeping and clock ticks, and a windy day with occasional far off dog barks.

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.
