SonyWF-1000XM4 Noise Canceling Truly Wireless Earbud Headphones with Alexa Built-in, Silver

I am generally very pleased with these earbuds. Sound quality is excellent and the noise cancelling very good. My only gripe is that the ear tips get dirty and start falling apart rather quickly and replacements are difficult to get hold of and are rather expensive (£27!)

I bought these used. They do work fine and noise cancelling is pristine. However, from time to time the right piece loses connection and I need to tap it 2-3 times until it re-connects.

Estos son uno de esas compras que quedas tan encantado con ellos que si se me perdieran los volvería a comprar, para el viaje en carretera que hago mucho, se han vuelta una pieza clave con el comando de voz que capta muy bien las órdenes.Solo tengo un pequeño comentario, si bien su sonido no se compara a unos audífonos de estudio, su calidad si es bastante buena, con agudos muy claro, pero si les falta poder a los bajos.Como comenté, no es sonido de estudio, no busques eso, pero si es el mejor sonido en audífonos inalámbricos y su cancelación de ruido es brutal, en carretera sin exagerar, es como ir sordo, talvez la principio me costó acostumbrarme a su máximo de sonido, porque ya me había acostbrado al fuerte sonido de mis audífonos en casa con amplificador, pero no paso de la semana y ya me había aclimatado.Por último, tocaré el punto negativo que es algo muy personal, pero que es lo que más tarde en acostumbrarme que es la comodidad, si bien, la caja trae diferentes tamaños de copas, llega a un punto en donde empiezan a irritar y como que sientes que se quieren salir, en definitiva no son cómodos al principio, pero poco a poco te acomodas a ellos y te acostbrado y luego ya ni te acuerdas de ellos, pero si toma más tiempo del que yo hubiera cr ido.En fin, si lo que buscas es lo mejor en cancelación de ruido y calidad de sonido sin tener todo un aparato de diadema en tu cabeza, simplemente no vas a encontrar nada mejor y si los compras con descuento pfff olvídate.

Value for money. Effective ANC.

Me encantan!Funcionan de maravilla, la cancelacion de ruido es genial, en la mayoria de lugares podras escuchar sin problemas tus audios sin que te interrumpa el sonido externo.Son algo grandes, pero puestos la verdad no lo sientes, no te estorban.No me gusta, que a veces los apagas con la app y cuando te los vuelves a poner, unas horas despues o al dia siguiente, a veces, alguno de los auriculares no tiene bateria, como que se volvio a encender y quedo activo.

I am EXTREMELY picky when it comes to earbuds, and I have to say, these are almost unexpectedly good. In the past couple of years, I have tested multiple brands of earbuds, cheap and expensive. These are unquestionably the best. There are a few cons, but the pros outweigh the cons by a long shot. Let me start with the cons:CONS:1. The memory foam tips are not durable. They certainly provide much better sound isolation than silicone tips would, but be prepared to purchase a bunch of replacement tips right away.2. Ambient sound could be just a little louder. The level of ambient sound is adjustable (fantastic feature!) but even at its loudest setting, it feels a little too muffled for me. When I am out in the street, I would like to hear the cars approaching and other street noises a bit better, especially if I am jogging. But it isn't bad. I guess I am just used to Buds Pro, which actually amplify external noises a little bit during ambient sound.That's it on the cons!PROS:1. The equalizer and other adaptive sound settings are incredible. Although be prepared that it won't be excellent right out of the box. In fact, the factory settings might suck. But the equalizer settings are superb, so you should be able to adjust it to your liking very quickly. Your first step is to make sure you identify which ear tips fit you best, as it will make a major difference in your sound adjustment. Once you've got the right size ear tips, you can start adjusting the sound settings on your phone. I would start with the phone's own settings first, and then go to the Sony Buds app and fiddle with the equalizer there. It comes with an app that has a variety of other smart settings. For instance, the level of noise cancellation and the volume of ambient sound can be adjusted. You can also program these buds to recognize the environment you are in, and have a few pre-set operation modes, such as for sitting at your desk at the office versus walking in the street, versus jogging. And the buds will adjust ambient sound, noise cancellation and other features based on your pre-set modes for the above conditions. You can also have several equalizer settings customized and saved.Since I have an Android phone (Samsung, to be exact), I started with first adjusting the sound on these earbuds by going to Samsung's own sound settings and customizing my equalizer through the "Adapt Sound" menu. And then, when that was done, I went into the Sony Buds app and worked with the equalizer there. It allows you to play music straight through that app (via Spotify or whatever else you have) and adjust your equalizer while music is playing, so you can hear the difference right away.For those who don't know how an equalizer works, I strongly advise you to watch a couple of YouTube videos on that first, so that you know what you are doing. A lot of people discard good earbuds and headphones because their sound is "bad" when in fact they just don't know the first thing about setting up the equalizer. I am very picky and demanding in my music settings. I love having such a strong bass that my spine feels the vibration (slightly exaggerating here, but only a little bit), but at the same time I like to hear the vocals loud and clear without distortions. I like hearing high-pitch vocals, and yet, I am not too fond of having excess treble. On most of the earbuds I've tried before, achieving such highly customized sound was impossible. But these Sony buds promised and delivered. I got my settings exactly how I want them, and it is pure heaven.2. Amazing sound cancellation. Here is what I mean. They don't just cancel out external noises. They are very smart about distinguishing between different types of noises, both incoming and outgoing. And you can program the sound cancellation settings to differentiate between, say, human voices and cars honking. As a result, I can listen to music while vacuuming and not hear the vacuum, but if my roommate talks to me, I will hear what she's saying because that's how I programmed my buds.3. Excellent sound clarity during phone calls, even in loud surroundings. I was recently riding my bike with wind whistling in my ears, but I could clearly hear the person I was talking to, and the person could hear me just fine. They didn't hear the wind, and my voice was loud and clear, and not cutting out. This, to me, is just unbelievable. I have not been able to get this with any other earbuds. Buds Pro, for instance, are absolutely impossible to talk to in any loud surroundings. Some other brands, cheap and expensive alike, do a good job of muffling background noises but they also muffle your own voice in the process. This is not the case with Sony Buds. They keep my voice clear while muffling everything else around me. I was also recently walking in the street, and there was a siren. Prior to that, I was in the ambient sound mode. When I heard the siren, I tapped on one of the buds to switch them to noise cancelling. I could barely hear the siren while still hearing the person I was speaking to loud and clear, and the person could not hear the siren in my background at all. I have no idea how Sony did it, but my hat is off to them for achieving such high-quality smart sound.4. Very comfortable. I was hesitant about getting these because they seemed bulky to me. I have very small ears and usually struggle with bulky earbuds. But these are very comfortable, probably mostly because of the memory foam ear tips. Once they are in my ears, they stay there. I've taken them out jogging and bike riding, and they didn't shift at all. Finding the correct size of the ear tips plays a key role here, so you should make sure you got the right size. But once you do, they are comfortable and stay in place for a while. And I didn't notice any burning sensation, or any other sign of earbud fatigue. They stay in my ears for hours, and I am comfortable.5. The case and the buds hold the battery very well. No complaints there. I am either listening to music or having phone calls all day long, and they hold the battery just fine.6. A function that I have not personally used: it allows you to sync the buds with two different devices at once. I don't like doing this, but this is probably a great feature for those who might want them connected to the laptop and the phone at once.VERDICT: Superb earbuds. 10/10 would recommend.

Let me summarize my feedback into the following points:1. Sound clarity is good and pretty balanced. I have been using the Jabra evolve 75 for over two years, which has good sound quality as expected from any high end headphones. I was surprised by the punch this little monster has.2. ANC is as good as high end Jabra or Sony over the ear headphones. I was walking down the street with ANC on and I literally couldn't hear the car behind me, it just sneaked up on me like a stealthy feline.3. A few people have complained about the fit, but I did 2 hours of gym, including running on a treadmill. The earbuds fits well, stays intact. No discomfort felt even after prolonged use.4. Customizations offered on the Sony app offers a great deal of flexibility. I would recommend some YouTube videos to go through if you are not expert in customizing the features on the earbuds. The speak-to-chat feature is a blessing, as it deactivates ANC automatically and allows sound to pass through as soon as you start speaking, so that you don't have to take the earbuds everytime you are speaking with someone.5. Sony did try something new with the packaging by using recycled materials. It is not that attractive, but the space management they did is noteworthy.6. Too early to comment on the battery backup. Need to observe it over some time. I was using the DSEE Extreme mode while listening to music, and I could see that it drained around 20-25% for 4-5 hrs listening time. It drains less battery with DSEE switched off.7. Although Sony earbuds beats airpods in the sound quality by a mile, the microphones however aren't the best in class as compared to the airpods. The latter has an edge over Sony on this point.
