truefree F2 Open Ear Headphones Bluetooth 5.3 Air Conduction Wireless Headphones Sport Earbuds with 16.2mm Enhanced Bass,Dual Mic for Clear Calls,15H Playtime,Multipoint Connection,App Control

These headphones are very light, the sound is crisp, and controls are responsive.The headphones sit over the ear and the speakers sit outside the ear canals, not in or touching the ear. The start, stop, pause, volume up and volume down controls are simple buttons behind the ear on the right side. I like the simplicity of the controls. One thing I especially like about this is that nothing is likely to trigger them unexpectedly like my wet hair or a light rain. I have fat fingers and don’t have any trouble with the controls.These are reported to have an IPX4 waterproof rating, meaning they are resistant to water splashes from any direction. As such, I have worked out and even taken a shower with them and have had no problems.As soon as I opened the headphones, I turned them on and paired them with my phone. I already had the truefree app installed for a different style of headphones. I opened the app and it quickly recognized the headphones.The first thing I did in the app was check the headphone charge state and I saw that the charge was full. Next, I clicked on the settings cog in the upper right and checked to see if the headphones had a firmware update pending, which it did. I hit the button to update the firmware and it was done in a few minutes.Like other reviewers, I noticed that the maximum sound was still a little low, however, I was familiar with the capabilities of the app. So, I went into a quiet room with no interruptions or sounds and did the hearing test in the APP. This adjusted the sound levels by creating a custom EQ setting based upon my particular hearing. I chatted with a friend for a little bit and the sound was very good.Next, I paired the headphones with my computer. I had turned on “Dual Device Connection” in the app. So, when I used to headphones to stream a film the sound source switched from my phone to the film audio. The clarity and crispness of the sound was excellent, even though I had a washing machine and dryer running in the hall.After wearing these for hours, I still find them to be very comfortable. They do have some angles in the form where they contact the back of the ear. I am very sensitive and after a few more hours, one of these spots bothered me. I rubbed it smooth with a fine nail file! This is the only minor issue I have with these. If that starts bothering me again, I am going to put a piece of moleskin on it!These don't move during dynamic workouts (jumping jacks, jump rope, box jumps, burpees...). Even when I am upside down doing handstands, they don’t even shift!They lasted at least 15 hours before I needed to recharge them. Recharge was fast and the covered recharge port was easy to access on the right arm. There is a red light to indicate when the charge is not complete which turns white when charging is finished (see photo).I have attached photos of the Charging state in the APP when it first said it needed recharging, then fully recharged again after 90 minutes of charging. Plus, I included an image of the Firmware update screen andI am very happy with these!
