Sony WH-ULT900
Type:full size (over-ear)
Connection:3.5 mm, Bluetooth v5.2
Кодеки:AAC, LDAC
Frequencies:5 – 20000 Hz
Battery:up to 30 h
Built-in amplifier (ULT button on the case for activation), enhanced bass, surround sound, adaptive noise reduction and good battery life.
Full-size over-ear headphones of the sturdiest mid-range class with a combined connection to an audio source. Specifically, the model features wireless Bluetooth v 5.2 connectivity, and you can unleash its full potential through a wired connection using a 3.5mm audio jack. The cable itself houses a built-in signal amplifier — the powerful sound of the headset is achieved by pressing the ULT button.
This is made possible by the combination of 40mm dynamic drivers and an integrated V1 processor. In wireless mode, the Sony WH-ULT900 offers more modest sound. The headphones are equipped with an advanced active noise cancellation (ANC) system with transparency mode, microphone noise reduction, and convenient touch controls. A full battery charge provides approximately 30 hours of music listening with noise cancellation and 40 hours of audio playback without it. Additionally, just a 3-minute charge gives you one and a half hours of subsequent autonomous operation. The model comes with a carrying case, and an additional audio cable. Flexible sound customization is available through the proprietary Headphones Connect app from Sony.

Model overview based on user reviews
Sony WH-ULT900 are comfortable over-ear headphones with strong noise cancellation, deep bass and immersive sound. Users especially praise the soft fit, transparency mode and convenient controls. The ULT button adds powerful low frequencies, although the strongest setting may overwhelm some mixes. Main drawbacks include an inconvenient app, plastic that feels inexpensive, occasional volume glitches and the lack of water protection.
Pros
Cons
I have been using the headphones for 2 months now, and they are amazing. The sound is balanced, and using them is a pleasure. The ULT button is a whole different story). Without it, you hear just quality sound without separately highlighted frequencies. When activating the first mode, you feel an increased bass, but it is pleasant, not "pounding" in your ears; in the maximum bass mode, you feel like you are at a concert, as if you are standing right in front of the speakers, with very vibrant bass, while the overall sound does not deteriorate and even becomes a bit louder. This is my first device with active noise cancellation, and I am immensely satisfied. When activated, almost everything that can interfere with listening to music (transport sounds, people's conversations, street repair work) disappears, and you feel like you are in a movie, separated from the surrounding world. The transparency mode is also excellent; sometimes you even forget you are wearing them, you can hear absolutely everything. When I tried them on for the first time in the store, they fit perfectly, as if they were made just for me, very comfortable, soft, and they don’t pinch at all, you can wear them for hours. The microphone was an important criterion for me, and it is excellent here, you will be heard perfectly even outside. It is hard to say about the durability of the ear cushions; only time will tell, the current result is in the photo. The battery is good, they charge very quickly (in 2-3 minutes ~20-30%, which is enough for at least an hour of use). Although the autonomy is good, I felt that 40 hours is not the case. The controls are convenient, the buttons are easy to find by touch. There is no water resistance here, so it’s better not to use them in the rain/snow. And they can't be hidden under a hood... Very high-quality sound ULT button for bass control Excellent noise cancellation and transparency mode Ergonomics Price (at first glance it seems expensive, but it is truly a worthy choice, with parameters on par with flagships) Convenient case Quality hinges Wired connection to the computer, specifically the quality of the microphone with this connection (possibly a feature of my PC), no complaints about the sound quality.  Dmytro Sheremeta: use Sony WH-ULT900 few months |
New headphones after QCY H4. The ANC here is really on par with flagship models, cutting out all the unnecessary noise. The bass is very deep and powerful, and on certain tracks, your head practically vibrates, yet the sound stays clear even at high volumes. In movies, there's a full immersion effect, making you feel like you're in a theater. The fit is excellent: the headphones are light, the ear cushions are deep and soft, with no pressure points. It's convenient that the ear cups swivel. The touch controls are particularly pleasing and responsive. Expectations were met 100%! The plastic feels quite cheap in the hands. The function sounds inside the headphones are unclear; instead of a voice, there are just sound effects that you need to get used to. The app feels very inconvenient compared to QCY, where everything could be customized in detail, but here it's somehow harder and almost nothing can be tweaked. I also noticed a weird bug: sometimes the sound drops for literally a second for no reason.  Rabotyaga: use Sony WH-ULT900 less than month |

Popular questions
How well do they block out noise on public transport?
Adaptive noise cancellation powered by the V1 processor effectively reduces the low-frequency rumble of subways, buses, and street noise. Combined with snug-fitting ear cushions, the headphones provide reliable isolation from the outside environment. To quickly hear an announcement or respond to someone, simply cover the right earcup with your hand to activate Transparency mode.Source:SpecificationsExpert reviewsUser Reviews
Are the headphones suitable for sports and running in the rain?
No, they are not suitable for workouts or wet weather—the housing has no water-resistance certification. In addition, the snug faux-leather ear cushions effectively block out external noise but allow practically no airflow. During intense physical activity or in hot weather, your ears will quickly feel stuffy.Source:SpecificationsExpert reviewsUser Reviews
How does the music sound, and what is the ULT button for?
These headphones are tuned for deep, powerful bass, while the dedicated ULT button switches between bass enhancement modes. The first level adds density and an expressive punch to tracks, while the second turns the sub-bass up to the maximum for fans of club music. If you want a more balanced sound for acoustic music or vocals, you can easily adjust the frequencies using the equalizer in the companion app.Source:SpecificationsExpert reviewsUser Reviews
How long does the Sony WH-ULT900 hold a charge with noise cancellation enabled?
A single charge provides approximately 30–32 hours of continuous listening with ANC enabled, while without noise cancellation, the headphones last up to 50 hours. With daily commutes to work, you’ll need to charge them no more than once every two to three weeks. If the battery does run out, a quick 3-minute charge provides about 1.5 hours of playback.Source:SpecificationsExpert reviews
How do I activate the voice assistant?
The assistant is activated by a long press on the touch panel of the right earcup, while Amazon Alexa also supports fully hands-free voice control. In the app, you can set up integration with Siri, Google Assistant, or Alexa to control your playlist, make calls, and get information without taking your phone out of your pocket.Source:SpecificationsExpert reviews
Can the Sony WH-ULT900 be connected to two devices simultaneously and used with a cable?
Yes, Multipoint support allows you to maintain wireless connections with a smartphone and a computer simultaneously, smoothly switching audio between them. For classic wired connectivity, a detachable 3.5 mm cable is included, and it works even when the battery is depleted. However, the USB-C port is intended for charging only and does not support wired audio.Source:SpecificationsExpert reviews
