O2 Open-Ear Headphones, Air Conduction Bluetooth 5.3 Wireless Earbuds, 22 Hours of Playtime, Four Mics Clear Calls, 15mm Enhanced Bass, Multipoint Connection, App Control, Commute, Workout

I’ve been using the TRUEEFREE O2 Buds for a while now, and they have exceeded my expectations! The sound quality is crisp, with deep bass and clear highs, making music and calls a pleasure. They fit snugly and comfortably, even during long listening sessions. The battery life is great, and the charging case is super convenient. Overall, a fantastic pair of earbuds for the price—highly recommend!

Love the look of the product. Sound qaulity is very good...very comfortable usuing.....battery lasts very long......light weight and amazing colour......love it🥰🥰

This product surprised me with the immersive sound without blocking exterior noise, they work really well and battery life is amazing. I also use them a lot in the office for calls and listening to music, without losing awareness of what's happening around me. They are very light which means I can use them for extended hours with no pain or uncomfortable feel in my ear. Controls work really well and have different functions, other similar products only change song or play/pause, but these also control volume and voice commands to Siri or alike. Never been able to go 100% on volume, they sound really well and with the customized equalizer you can adjust to your liking. My only concern is if I use them while running or cycling, I fear they may fall. Haven't tried it though.

I find these buds beautifully designed and very attractive to look at. The hooks sit comfortably in the ear. I use them for my outdoor run and I mist say they have really kept my workout more fun. For an open ear earbuds, I found the quality of the sound on these to be great and the voice clarity during calls excellent. Strong battery life and keeps me aware of my surroundings. Very nice. My outdoor run has become more fun.

My must have earbuds when I'm having online meetings. The Truefree Earbuds 02 deliver impressive sound quality and a comfortable fit, making them perfect for long listening sessions. With reliable connectivity and excellent battery life, they offer great value for their price.

I have been using this open-ear earbud for almost two weeks now and these are comfy and sound great even when it's away from the ear. Feels unrealistic when you think about how you can hear bass well even when it's not in-ear. Battery life is good for work use, I have used it for 1 full day without the battery getting low. The best part is even when u sleep and forget to remove the earbuds, you won't even know it's there as it's lightweight and it does not hurt your ear.

This Headphones are fantastic.It provide incredibly comfortable and perfect for workouts and commutes. The sound quality is impressive with enhanced bass and clear calls. Plus, the long battery life and dual connection feature are super convenient. Highly recommend.

It's easy to use while cycling and running hear clear sound with clarity.it holds perfectly on ear

SONIDO PERFECTO. OIDOS ABIERTOS . SINCRONIZACION CORRECTA. VOLVERIA A COMPRARLOS .

Mijn beste oortelefoon ooit: geweldig geluid en ik hoor mijn omgeving. Ik voel ze niet en kan er zelfs een bril bij dragen. Mijn vriendin heeft heel kleine oren en bij haar passen ze niet. Ik heb gelukkig grotere oren.

I will acknowledge that while I own many pairs of different types and brands of headphones, these are only the second pair of open ear headphones that I have owned; the first being the truefree O1’s. I can’t speak on how these compare to other open ear headphones aside from its predecessor, but I can speak on the quality of the headphones on a general basis especially keeping in mind that many other brands and models of open ear headphones are multiple times the cost. As far as how they compare to the O1’s, I think the O2’s are a nice upgrade in quality and they are listed at essentially the same price. I say this because I thought the O1’s were well worth the price so in my opinion these headphones are absolutely worth the price. As far as sound quality goes, they’re pretty good from an overall perspective. Don’t expect them to sound like really expensive headphones because they’re not, but these headphones also won’t run you hundreds of dollars. The bass is actually a nice surprise on these. They obviously don’t quite compare to something along the lines of medium to high quality studio headphones in terms of bass, but for headphones of this size and type the bass is better than expected even in comparison to the O1’s. These headphones can also manage a pretty loud volume. As far as comfort goes these headphones are very comfortable to wear. Though this is presumably true for many open ear headphones, they don’t lead to discomfort with prolonged use like buds and studio headphones do. I have worn them for many hours on end and have never had issues with discomfort or aching. In comparison to the O1’s these fit much tighter to the ear and stay on much better. I can and have gone for runs in these headphones and never had issues with them falling out of my ears. I haven’t even encountered moments where they felt like they “might” fall out. While on the subject of running, I haven’t specifically tested the water resistance of the headphones, but I have used them for runs and working out and sweat has never caused any issues for them. I can’t say I’ve timed the headphones’ battery life, but I’ve used them many times for 4-6 hours a pop and they’ve never died on me. I’ve used them for longer than 6 hours with breaks in between where I popped them into their case until resuming use and have never had them die on me in those instances. For example, if I’m working a long day, but take a 45-minute break for lunch I’ll pop them in the case while eating and then finish out the rest of my work day without having any issues with the battery. That said they seem to charge pretty quickly from the case. And the case itself charges pretty quickly as well. The case has a solid battery. I can’t say I’ve kept an exact record of how many hours of charge (for the headphones) the case holds, but the claim of 22 hours seems accurate if not an undersell. It charges the headphones automatically when placed inside and holds them into their places magnetically nice and snug. The case itself feels nice and solid and has a sleek design to it though it’s nothing super fancy. One of the things I really like about these headphones is that they connect within seconds of the case simply being opened. By the time I even have them on my ears, they’ve long been connected. And while there doesn’t seem to be a claim about the Bluetooth’s connection range, I have tested them out and found them to reach over 60 feet through multiple walls, walls, objects, doors and even all this in addition to exterior masonry walls. So that said the Bluetooth connection on these headphones is very solid. As far as the mic goes you can definitely tell that you’re using headphones from the other end of a phone call (though I find this to be the case with essentially all my headphones), but the sound quality comes through clear. I also find the sensitivity of the touch functions to be very ideal. They are just the right balance of being responsive without being too sensitive so you don’t end up triggering functions when you’re simply trying to adjust them. I know I touched on a lot and I’m sure there are some aspects/functions of the headphones that I skipped over in reviewing, but at the end of the day my final opinion is this: If you’re looking for a reliable, comfortable pair of open ear headphones without wanting to spend a lot of money to go super-high quality then these are well worth the purchase.

Super son très pratique pour le sport confort auditif top

Despues de usarlos por una semana les comparto mis experiencias con este nuevo producto de TrueFree que son la evolucion de unos excelentes auriculares de conduccion por aire, estos 02. Veo gratamente que la marca le puso enfasis a este upgrade que la verdad ademas de ser super comodos han mejorado en la calidad y potencia del audio, pero vayamos por partes. Hablando de la comodidad si tu eres de las personas que no les gusta traer algo "encajado" en el canal auditivo pues dejame decirte que este es el producto recomendado la verdad, no solo es como y liviano ademas de bonito (obvio esto es subjetivo) sino que ademas cuenta con una excelente duracion de bateria rondando las 6 - 7 horas con un promedio de 60% de volumen que de paso sea dicho creo yo es mas que suficiente para disfrutar de tu musica favorita sobre todo en ambientes no tan ruidosos como un cafe, una banca en el parque y lugares asi ya que si los utilizas para por ejemplo andar en bicicleta o ir caminando por la via publica puede que requieras de un poco mas de volumen pero aun asi su duracion en bateria sigue siendo segun mi perspectiva bastante bueno sinceramente. Estos auriculares alcanzan un volumen alto por lo que veo muy poco probable que los vayas a llevar hasta el limite de su potencia pero claro dependera de cada quien... cuentan con multipunto por lo que puedes conectar dos dispositivos (solo pudiendo usar uno a la vez) y tienen BT5.3 lo cual es de lo mas nuevo que hay en el mercado por lo que no debes de tener problemas con compatibilidad en diferentes gatgets de reproduccion de sonido... su driver es dinamico y es de gran tamaño, muy grande de hecho lo que le brinda esa subida fuerte de volumen pero no por ello dejando de lado la calidad del audio ya que cuenta con muuuy poca distorcion a altos volumenes (nada que una buena ecualizacion no solucione). Su case de guardado que al mismo tiempo funciona como centro de carga para los auriculares les permiten un par adicional de cargas por lo que no tendras preocupaciones tampoco en ello y en la cajita viene su cable el cual es tipo C que ya es el estandar de mercado actual... la carga del case es de alrededor de un par de horas mientras que los auriculares al estar dentro de ella se cargan mas o menos en poco mas de 1 hora al 100% si esque los dejaste completamente sin carga. Hablando de sus controles estos te permiten tener todas las funciones necesarias para controlar tu musica, el asistente o el modo juego de baja latencia y algo que me parecio por demas excelente es que la aplicacion para tu digamos celular android ademas de actualizar el firmware de ellos tambien te permite cambiar lo que deseas que hagan segun los gestos que hagas en cada auricular ya sea el izquierdo o el derecho por lo que de verdad estan muuuy personalizables y muy funcionales asi que un 100 ahi para la marca. Cuentan con microfonos para ser usados como manos libres dando un muy buen nivel de claridad si los usas para las llamadas y te permiten contestar sin necesidad de sacar tu celular de la bolsa o bolso segun sea el caso asi que de nuevo, muy bien ahi en los controles tactiles. Hablemos del sonido que a fin de cuentas es creo yo de lo mas importante ya que obvio son auriculares para escuchar musica y algo mas... los agudos estan bien presentes pero al ser de conduccion aerea hay que ecualizarlos bien ya que este tipo de frecuencias son las que menos se pierden al "circular" por aire asi que bien ecualizada tu musica no tendras problema alguno con ellos; los medios rangos estan bien traidos al frente y muy claros la verdad asi que las voces en las canciones no te daran problema alguno; lo mas dificil de ecualizar a mi parecer son los bajos ya que al ser un driver tan grande si adicionas demasiado puedes "cartonear" un poco en la musica pero si le encuentras bien el modo creeme que estan bien distribuidos, fuertes y de buena intensidad exceptuando el bajo que yo denominaria profundo el reverberante tipico por ejemplo de rap o del hiphop ahi puede que te falte un poco mas de contundecia pero es obvio por el tipo de producto de sistema abierto y vamos a ser honestos ya que este tipo de auriculares estan pensados para el deporte y las actividades al aire libre o de gym asi que estas consiente del uso que les vas a dar creeme que los disfrutaras mucho. La verdad estoy muy complacido pues veo que la evolucion de los anteriores 01 a estos nuevos 02 fue muy buena en todos los puntos por lo que sinceramente no veo inconveniente en que estos sean mis nuevos auriculares deportivos y los otros pues se los regalare a uno de mis familiares ya que esta evolucion es perfecta de la marca... el precio si hay claras diferencias con los anteriores peeero viendo los beneficios y el crecimiento satisfactorio en funciones potencia y sonido pues creo yo que lo valen sinceramente. Gracias si llegaste hasta aqui y espero que mis puntos te sean de utilidad si tienes pensado adquirir este muy buen par de auriculares TrueFree 02... no te vas a arrepentir y si tienes las espectativas centradas en el uso para lo que fueron concebidos pues la verdad te esperan horas de difrutar tu musica en ellos... Saludos y Felices compras!!!
