Review: Amazing sound, long play and lightweight wear open-ear headphones - 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 desertcart Questions. Once you get signed in the first time, you don’t need to do it again. Watch the video in desertcart 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.
Review: Great Sound and Comfortable Fit - This is my second pair of "open-ear" earphones. The Truefree O1 Open Ear Headphones are so much more comfortable than traditional earbud models. They provide excellent sound and allow for ongoing awareness of your surroundings --which may make you safer in some settings (walking on a public sidewalk, crossing a street, or cycling). I find some traditional earbuds uncomfortable, even slightly painful. The open-ear style is very comfortable. I'm able to listen for hours without getting a sore ear canal. The Truefree O1 earphones also stay put during activity --exercising or working around the house. They don't fall out like regular earbuds. There is no sacrifice to sound quality. Excellent rich and immersive bass and treble. I can't detect any decline in the quality of the listening experience, having the speaker lying over my ear vs. having the speaker inside my ear canal. The Bluetooth paired instantly and automatically on these Truefree O1 Open Ear Headphones. I've used these for hours and found battery life to be excellent. The charging/carrying case is built well, compact, and convenient. The overall build quality of the earphones is great --they feel sturdy. The noise canceling function works extremely well on phone calls and video calls. Background noise is nicely filtered out on calls. You will not be disappointed with these Truefree 01 Open Ear Headphones!

### ⭐⭐⭐⭐ Good budget Open Ear headphones, dont expect booming bass.
*by D***B on October 21, 2023*

These headphones make for a good option if you want open air pass-through sound. Theses headphones serve a specific purpose; if you want to be able to hear what's around you while listening to music. Ideally this is great for working out or running if you want to be able to hear cars as you're running on the side of the road for safety, these are it! You have to know that going into purchasing headphones like this because you can't expect the same booming quality sound with headphones like this that you would get out of in ear buds. That being said the sound quality is good it serves its purpose for listening to music. The bass is lacking, but that's to be expected. These feel pretty light around my ears not cumbersome. Did bot get uncomfortable after a few hours of wear I was able to run with them And they didn't fall out of place. It comes with a USB a to USB-C charger cord. Thumbs up for going USBC. Connection to my phone was incredibly easy It took no time at all and they came fully charged out of the box. The carrying case however is pretty large as you can see in the picture but these are also larger style buds that wrap around your ear so the case needs to fit a larger object. I wouldn't stick this case in my pocket to walk around with bc of the size, but perfect fit for a backpack or purse or small carrying crossbody bag. Definitely recommend if you're looking for an open ear style headphone. Battery life is solid with ab 10hrs on the headphones and another 45hrs from the case.
