Eu gosto muito de nadar com esse mp3. Fico mais tempo dentro da água. Para quem nada é gosta de música, vale muito!

Just a massive fan, these are the first headphones of their kind I've owned but they did not disappoint at all. Certain elements of getting the songs into the device felt a bit archaic but that was a one time relatively minor hassle. Now that I've gotten it nice and loaded it does its job very well and certainly makes my swimming sessions a lot more enjoyable.For the sound quality, definitely don't expect perfection. I have no point of comparison so maybe other headphones do simply sound completely normal, but they sound solid enough for me to get into the music at least.Comfort is alright, I've never liked in ear plugs so these share the same annoyance I already feel towards those kind of earphones, but I was pleasantly surprised that they don't tug away at you as you move through the water or anything like that and since I only wear them for a swimming session at a time (around an hour) my ears don't get tired or anything like that.I've only had these for a short time so I will update if over time they break down easily.

The quality of music isn't goodAlso isn't confarable to keep on for log time, specially for running

Yes, you read the title right! I hated swimming; you cant see, you can't breathe, you cant hear and is closterphopic. At middle age I also knew that it was one of the best exersizes. When I saw the ratings, I was reluctant. Despite the 3 1/2 star rating, I bought these headphones. I have rated many items. (Check out my reviews. ) These underwater headphones are the *BEST* purchase I have ever made on Amazon! Here's the details:Generally, I had no idea how to work these things. Also, I'm not a Tecky. If I have one criticism, out of the box, the directions were a little confusing as they rely on drawings rather than words. So, it took a while. The charger fits into the headphonse the opposite of how you might think. Took a few minutes to figure this out. Once I fugured out how to charge it I purposely uploaded music from I-tunes. I stopped after around 3-4 hours of tunes. I could have added more if I had wanted. Adding the music was easy.So, you'll notice that these are not big nor are they obtrusive. That's why they are so great for swimming. The downside is that the buttons are necessarliy small and hard for an old guy to see. At first you'll need to refer to the directings often. Again, I'm not a Tech geek and I figured it out.Wearing them: The first time I wore them it was magical! Listening to music stops the insessant and panic inducing splashing of swimming! A side benifit is that the earplugs block water from entering the ear canal! I looked like some kind of wierdo as I smiled and enjoyed swimming for the first time.Staying in postion: I was worried that they'd fall off. The design is so out of the way and comfortably snug that they have NEVER fallen off! It's kinda amazing. I wear them with goggles and I have more troupble with the goggles.The sounds quality: Look, you're swimming. It's hard to expect to hear a concert while your're underwater. The sound quality is much better than I expected.The battery life: At first, I kept forgetting to press and hold the power button after use, leaving it on. The next time it was dead (Duh!) Since I've started shutting it off after swimming (...I hate doing this because I picked songs I love!) the battery life is actually quite amazing. I swim for 30-40 minutes and can use it 4-5 times without worrying about charging it. I often leave it in my car and it gets below freezing where we live. My ears are damn cold but these things still work!Overall quality: It's been 1 1/2 years. The Sony underwater mp3 is still going! It has NEVER failed. It's never fallen off. It's never gotten messed up by waters. They are extremely well-made.I can't explain the bad ratings by other users. Read them and use your own judgment. Also, review other underwater MP3 players. None of them are rated well. I wonder about users expactations. My experience is absolutely the opposite.This was money well spent!So, I hated swimming. Because of these headphones, I swim 3x per week. I love it. I hate to take them off after I swim. I tell people about them all the time.Again, check out my ratings. I am a pretty generous rater but never this enthusiastic.These are GREAT!

Muy buenos audífonos, nadar fondo puede llegar a ser muy aburrido. Son los terceros que compro de esta marca y me encantan, el tiempo de vida es de aproximadamente un año, los uso de lunes a sábado, entrenado dos horas diarias. También los he usado en mar y en río y su funcionamiento no ha disminuido.No sirven para nadar a velocidad, pues se salen del oído, yo los uso dentro de la gorra para nadar fondo y son excelentes, tienen buen volumen y además sirven como tapón para que elAgua no entre a los oídos. Son de buen tamaño y no estorban al brasear

Es muy buena opción para hacer tu entrenamiento de natación con música, el sonido es bastante claro y la batería es muy duradera, recomiendo que lean las instrucciones ya que si no pones las almohadillas correctas NO SON CONTRA AGUA

He sido muy cuidadoso de los audífonos y han empezado a fallar, no sé cuánto tiempo tenga de garantía, pero los he limpiado y usado como se recomienda; sin embargo, empezó a apagarse, luego a no funcionar el botón del modo de reproducción (repetir, shuffle, etc.), luego empezó a repetirse la canción, sin poder avanzarla, después a saltarse las canciones, en fin de plano hoy ya los daré de baja, pero no es posible que no dure ni un solo año!!!

EL PRODUCTO CUMPLE LO QUE OFRECE, EL SONIDO ES BASTANTE BUENO, SI BIEN SI SE ESCUCHA EL AGUA Y UN POCO LAS BRAZADAS, YA DEPENDE DE LA CAPACIDAD AUDITIVA DE CADA PERSONA SUPONGO PUES EL VOLUMEN MÁXIMO A MI ME FUNCIONA PERFECTO, 100% RECOMENDABLE

Aunque se pierde un poco la calidad del sonido al sumergirse la verdad es que estos audífonos de entrenamiento son maravillosos y de los mejor en el mercado. Me equivoqué al pensar que eran bluetooth, tienen suficiente memoria y es muy fácil cargarles la música

Dura un poco la pila, un poco complicado de poner al principio pero te acostubras.

Lo compre a pesar de que dicen q baja mucho el volumen nadando. Pero si se graban bien las canciones con buena calidad, se escucha muy bien. Aparte hay q ajustar muy bien al oído. La batería dura un poco menos de lo que dice durar. Pero a pesar de eso es un excelente reproductor para escucharlo en la alberca.

Buenos audífonos.Pros.Son de buena calidad, fácil de utilizar, fácil de cargar la batería, es muy fácil introducirle los mp3. buen volumen (dentro del agua), nado con ellos todos los días 1 hora y me dura la batería el fin de semana los tengo que poner a cargar. los he utilizado en el mar y alberca sin ningún problema.cons.Tardas en acostumbrarte para ponértelos, al principio son un poco incomodos si no te los acomodas bien, cuando se acaba la batería te avisa y se apaga no te deja terminar ni la canción.Después de 8 meses dejaron de funcionar, no los puedo recargar.

Music really enhances lap swimming for me. Of the variety of ways to accomplish this I chose the previous generation Sony NWZW273S. It got the job done, I like the simplicity of design to put on and take off without being attached to my swim goggles.The older model also had some drawbacks. Chief among them was lack of volume and then for me keeping the contacts clean for charging and adding music.This new model definitely fixed the volume issue. I actually turned it down from Max, which is great. The docking, charging station looks like an improvement, but it's too early to tell. The controls are completely different, but I think with a little time they will be an improvement. The ear pods are slightly larger on this newer version, which was a concern, however they are light weight, fit very well and more importantly stayed on well in the water.The software is the same for both units which made adding music to the new unit a snap. The software interfaces smoothly with iTunes.** UPDATE ** 7/7/16 I picked mine up early May '16 liked it so much I bought another for a friend towards the end of May. We each swim for an hour 5+ days a week. So I've used mine ~ 40 times in a chlorinated public pool and my buddy, who swims in salt water, has used his about 25 times. So far these units are holding up great. With the non-water ear buds the volume can be WAY too loud, when the swim buds are put on it does reduce the volume as they are essentially a shower cap to keep the speakers dry, with a membrane between your ears and the speaker. Without the swimming ear bud covers the unit would die in the pool from the speakers getting wet. The music, for me at least, is plenty loud and I typically go a click or two down from full volume.** UPDATE ** Oct '16 ** The two units I bought are going strong six months later. Each sees 5+ days a week of hour long lap swimming. One is in a standard chlorinated pool, the other in a salt water pool. I haven't had any problems with my contacts for charging or adding music and I haven't done a thing to clean them. Mine will play an hour interval 3 times before it needs a charge.** UPDATE ** Nov '17 ** Both units still working, one perfectly the other is having issues with song forward button not always working but otherwise still serviceable. I'll definitely buy another if this one dies.
