seems good
These were for husband and he's been using them for running almost daily and seems to be still working fine after many months.

Extremely happy with these
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 🕶️

Better than their other models!
I think these are way better than the other version. I tried the other version, and they didn’t work for me. However, these are more consistent, feel nicer on the ear, and work reasonably well for the price. If you're budgeting, these are great. If you have a bigger budget, I’d suggest spending more to get a better pair. That said, these are not bad! They do work, but I’m told they work better with Android than Apple. However, I am using them with Apple, and these ones are okay.

Budget alternative bone conduction headphones
Setup During the setup process, I found connecting these to my iPhone 15 Pro to be a seamless and efficient process. I have consistently experienced smooth pairing with the headphones on multiple occasions. Battery life I tested these during a lengthy bike ride and was able to use them for an extended period without any battery issues. The inclusion of a charging case with USB C proves to be practical for storage, cleanliness, and ensuring the battery remains charged. I also took several phone calls and was able to hear the other person clearly. Comfort The headphones do not provide a secure fit and are too loose. For those seeking headphones specifically for running, you may want to look at the SHOKZ OpenRun Bone Conduction Sports headphones instead as they offer a better wrap-around design for a more secure fit. I feel Truefree should look at designing these so they fit well to the ear without being loose. Target audience After thorough testing and reflection, it appears that these headphones are designed for individuals who engage in regular physical activity and value the ability to hear their surroundings while enjoying music and taking calls. While bone conduction headphones are an alternative, they can be cost-prohibitive, making these headphones a more accessible option. It is important to note that individuals who prioritize music quality over the need to hear the surrounding environemt may not find these suitable for their needs. Disclaimer: I have been sent this product as a free sample to test and unbox. This has not affected my opinion of the product.

Unbeatable value for money
I was looking for a set of open ear Bluetooth headphones without a band, that wrapped around the ear so they felt comfortable and wouldn’t fall out in the gym. I’ve tried the market leader bone conduction type but as others have said these broke down after 2 years and the band prevented relaxing back with head resting against something. I have also tried other in ear models but I don’t have a ‘slot’ in my ear to ‘lock’ those types in and the ones that rely on a snug inner ear fit always feel like the bulk on the outside will through gravity or movement eventually make them fall out and risk loss in public environments. These TRUEFREE phones address all these problems and give a great sound for the price. The addition of an app allows you to tweak the equalizer or play white noise if wearing them in noisy office environment. I found the touch sensitive controls a little fiddly and not successfully managed to pause the media from playing with the double tap but that is possibly user error. It would be nice if they could go slightly louder as I have found in louder environments there’s not enough volume to block out louder noises, but this may be a by product of them being open ear anyway.
