I’m very picky when it comes to headphones, they have to be perfect and these definitely are!! They’re great for listening to music or audiobooks. The noise cancelling is spot on, absolutely no background noise and no leaking of sound. They’re comfortable enough to be worn for a long time and they fit over my ears perfectly. Bluetooth couldn’t be any easier to connect it found my iPhone and kindle within seconds plus you can connect 2 devices at the same time, so if I’m listening to an audiobook on my kindle I won’t miss any calls as my phone can be connected as well. They came in a good quality case which is so much more practical and safer than the bags some headphones come with.The battery lasts a long time sometimes I charge them once a week but can go longer.I really love these headphones, they’re comfortable, good quality and the sound is perfection. I would highly recommend these and I’ll absolutely be sticking with Sony from now on

It’s hard to believe but these WH-1000XM4 headphones have been on sale for about five years now. There are now two models newer than this, imaginatively named the XM5 and the XM6 both of which offer improvements on this XM4 model. But these XM4s are amazing quality and at the moment about half the price of the newest XM6 model.The active noise cancelling of the XM4 headphones is very good. I often travel on the train with these and they are great at deadening the outside noise of the train (and are especially good at quietening diesel trains!). But they also significantly quieten those annoying travellers who have to share their music, loud comedy clips and telephone calls with everybody else! It keeps you sane when travelling and allows you to listen to your music or movies in great quality.I am particularly impressed with their bass capabilities which underpin a great depth and richness of sound.These headphones can be managed through Sony’s Sound Connect app which gives you quite a degree of control over the various features of the XM4s, in particular the ability to change the noise management according to the environment.The battery life of the XM4s is very good, stated in the literature at about 30 hours which seems about right to me.The call quality of these headphones is good, both in terms of the pickup from the microphone and the audibility of the caller in noisy environments. I understand that the XM5 and XM6 both have superior microphone and noise cancelling but this obviously comes at a greater cost than the XM4 which I find very much suits my needs.There are many technical explanations of the attributes and differences between these various models on the internet and it is clear from those that the latest XM6 model is technically improved in various ways.But if you are on a budget, as I was when I bought these, I think that the XM4 headphones are fantastically good value for money. I’m really pleased with them and give them top marks.If you want to get a pair, now would be a good time as it’s hard to imagine that they will be around for very much longer when there are two newer models available.

Sonido, calidad de construccion y comodidad top
Estos auriculares son, sin duda, los que recomendaría a cualquiera que use transporte público, entrene en un gimnasio o viaje con frecuencia. Su punto fuerte es la excelente cancelación de ruido, que te aísla del entorno de forma sorprendente y te permite disfrutar de tu música sin molestias externas.Además, son muy cómodos incluso tras largos periodos de uso, y resultan fáciles de transportar gracias a la funda de buena calidad que incluye la propia marca. Todo está pensado para que los lleves contigo a cualquier parte sin complicaciones.En cuanto a los contras, mencionaría dos.El primero es la app para móviles, que no termina de convencerme: para ajustar ciertos parámetros tienes que estar entrando constantemente en ella, y se hace un poco engorroso.El segundo es el micrófono, que deja bastante que desear. Para llamadas, audios o videoconferencias la calidad no es muy buena y no se escucha demasiado allá, especialmente comparado con lo bien que rinden en el resto de aspectos.Por lo demás, un 10: gran sonido, comodidad y una cancelación de ruido que sigue siendo de las mejores del mercado. Una compra que rara vez decepciona.

Love it.
the product is very good specially if you are a traveler, there is no much difference from Sony WH-1000XM4 and Sony WH-1000XM5 only ANC is a bit better on the newer modle.
