Faultless for the price
For the price, especially Vs more expensive options, they're faultless. Have used some more expensive options and they didn't last. They don't sound as good as more expensive options but honestly, for the price difference, it's a fair compromise. You're never going to get anywhere near audiophile quality with open ear headphones. Highly recommend.

Good sound
I find them a bit difficult to use but is the nature of touch controls. Finally getting the hang of them .

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.

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 🕶️

cuffie wireless comode, affidabili e con un audio pulito
Le truefree Cuffie Bluetooth 5.3 ad orecchio aperto sono davvero un ottimo acquisto! Il design con ganci per orecchi le rende super stabili e piacevoli da indossare, ideali per chi le usa mentre si muove o fa attività fisica. La qualità del suono è sorprendentemente pulita e bilanciata per il prezzo: voci chiare, bassi definiti e zero distorsioni anche al volume medio-alto. La connessione Bluetooth 5.3 è veloce e stabile, senza interruzioni fastidiose. Una delle cose che mi ha colpito di più è il comfort: dopo poco ti dimentichi di averle addosso — non danno fastidio anche durante ascolti prolungati. La durata della batteria è eccellente, davvero ci si può contare per ascolti prolungati fuori casa o in viaggio. In sintesi, ottime cuffie wireless comode, affidabili e con un audio pulito. Consigliatissime! ⭐⭐⭐⭐⭐

customer support was helpful
The first pair I received stopped working about 4 weeks after purchasing. But I contacted support and they were incredibly responsive and helpful and remedied the situation immediately. I have now been using my replacement set for months. I am completely satisfied with my purchase. The quality is probably even better than the value for money.
