Otra novedad de los XM4 es algo llamado DSEE (Digital Sound Enhancement Engine). Junto con el nuevo software de inteligencia artificial, mejorará la música digital comprimida en formatos como el MP3 o AAC llenando ciertos huecos de forma que desconozco para brindar una experiencia más completa. Con todas estas nuevas mejoras, puedo notar una diferencia de calidad de audio entre el XM3 y el XM4. Sony claims 20 hours of battery life without defining what mode. Other headphones sometimes have decreased battery life with HFP (phone calls). These definitely exceed the rated battery life. With the first charge they lasted almost a week of varied use. I used them for a multi-day virtual conference, and other meetings (combination of HFP and A2DP) for over 14 hours, and they still had 60% charge. Sony doesn’t specify any longer battery life with the wired cable. On the Bose I would plug the cable in when I would go to sleep on international flights, and Bose quoted 40 hours like that, so 20 hours isn’t fantastic. It is more than enough though. It will get you through the longest flight plus some other use. Almost any other use it should be more than enough. I used them over 10 hours straight one day and they were still around 70% charged. At 254g, the Sony WH-1000XM4 are a mere one gram lighter than the WH-1000XM3, but that weight is distributed more thoughtfully. The plastic earcup housing has been slimmed down in favour of adding additional padding to the pleather lining the inside of the cups, while the headband padding is slightly thinner. The section connecting the headband to the earcups has been shortened too, resulting in a fit that is better contoured to your head.

El otro elemento importante que cambia las reglas del juego con respecto al modelo anterior es la capacidad de los audífonos para detener la reproducción cuando te los quitas y se reanudan cuando te los vuelves a poner. Esto es algo que se ve regularmente en los auriculares (como el WF-1000XM3), pero finalmente lo estamos obteniendo también con los audífonos de gama alta alrededor de la oreja. Esto también es extremadamente útil ya que ni siquiera tengo que apagarlos más porque, cuando me los quito y los vuelvo a colocar en el estuche, estos se apagarán automáticamente, aunque no la uso mucho porque me gusta ignorar a las personas que no respetan la música que estoy escuchando, aunque cuando tenía esa característica activada funcionó exactamente como se anuncia, lo que supongo que es una consecuencia de la mayor cantidad de micrófonos comparado con modelos anteriores que también mejoraron maravillosamente la calidad de las llamadas y absorbieron ruidos molestos. The audio quality on phone and video calls has been excellent on the receiving side and is about as good as Bluetooth HFP profile gets. it is excellent for conversations. With the excellent noise cancellation these are excellent for long video calls. They will likely continue to be great for those forced to endure a noisy open office environment, or need to make phone calls in a noisy area such as an airport or train station. Though the event proper won't begin for a little while yet, if you're looking to buy sooner, you can take a look at the best discounts available from the major retailers just below. Bluetooth range is excellent. It would easily stay connected when going from one area of a reasonably large house to another. The range exceeds any other Bluetooth headphones.The automatic speak to chat feature is both great and annoying. At least with the sensitivity set to automatic it will detect voice quite well and stop the content you may be listening to, and allow ambient sound to be heard. This, when desired is far more convenient than Air Pods Pro where you have to hold be button for a few seconds to go into transparency mode. While you still can’t hear what someone says to you, at least when you reply to them, it immediately lets you hear them, and doesn’t take the seconds the Air Pods do. With AirPods you also need 2 actions to stop music and enter transparency mode. This mostly works. In the automatic mode it doesn’t need to actually be voice that triggers it. Anything like a grunt, large breath, anything it seems will trigger it. The slightest grunt or sound and they stopped the music and went into ambient mode. There is a low sensitivity mode that I haven’t tried yet. You will find this feature to be a love/hate relationship after a while. Even with the “Focus on Voice” feature enabled this still seems to be overly sensitive. They may be pricey but they’re worth every penny: put simply, the Sony WH-1000XM4 are the best over-ear wireless headphones on the market. Sony WH-1000XM4 review: What you need to know

SONY WH-1000XM4 Wireless Bluetooth Noise-Cancelling - Currys SONY WH-1000XM4 Wireless Bluetooth Noise-Cancelling - Currys

Prices valid in stores (all including VAT) until close of business on 1st November 2023. (Some of these web prices are cheaper than in-store, so please mention that you've seen these offers online.) Sonic performance is a big upgrade compared to the older WH-1000XM3 and they sound better than rivals including the Bose Noise Cancelling Headphones 700. The XM4 soundstage is wide and unearths loads of detail, and they're composed and confident when it comes to low frequencies. Dynamic shifts are handled with aplomb, and they have plenty of enthusiasm for every genre you care to listen to. Services availability depends on region. A part or whole of software/services installed into or accessible through the product may be changed, discontinued, removed, suspended, or terminated without notice. Por eso debes definir bien para qué los quieres, no me atreví a poner 5 estrellas pero tampoco 1, porque depende de tus necesidades, en mi caso quería para todo lo mencionado, pero al parecer no he podido encontrar nada en el mercado que lo tenga todo, algunos son buenos con el microfono pero pésimos con el audio, otros alrevés. En este caso el microfono es un asco, lo más que podrás hacer es contestar llamadas en tu celular en calidad pobre, busca en los foros de sony y verás cómo la gente se queja del microfono.Phenomenal sound, quality & a decent price I bought this a couple of weeks ago & waited until now to review as I wanted to give them a test run in the city. The sound quality is incredible, using the app it’s really easy to change and personalise your settings, but I can’t fault the auto-optimiser. I honestly cannot believe how good the noise cancelling is on them, sounds of the city are practically non existent once they’re on. As for automatic detection of actions, that can be very annoying. It was fine when sitting in one place. Initially I didn’t know why EVERY time I bent down the headphones would beep and go out of noise cancelling mode. Then resume playing normally. This is apparently the notification for detection of actions. This can be disabled in the app. If someone were to use these headphones in a gym or exercising this would be annoying as well. (Note: These are NOT sport headphones!) Adaptive Sound Control automatically adjusts ambient sound settings to suit your location and behaviour The Sony WH-1000XM3 were best-in-class when it came to noise cancellation but this model is even better at regulating the amount of external noise that makes it through to your ears. With noise cancelling in full effect, the WH-1000XM4 let you slip away into your own audio world, free of all-but the loudest and highest-pitched annoyances.
