Note: The latest firmware update (2.4.5) apparently “improves the hands-free calling quality,” though we still notice some muffling during calls. All calls sound loud, but not crisp, and some clients and friends complained about audio being choppy. The WH-1000XM4 is the better calling headset, but despite being an upgrade, the results aren’t noteworthy. For personal calls around the house or outside, not so much.
If you’re looking for headphones that serve well for home office use, sure, either the WH-1000XM3 or WH-1000XM4 will suffice. You can hear the string section coming from your left and the brass section coming from the right, along with the audience to simulate the feeling of being in the crowd.
The results are pretty impressive, allowing you to hear individual elements from different points, sort of like if you were sitting in an auditorium watching an orchestra play on stage. Think of this as Sony’s answer to Apple’s spatial audio, only it doesn’t use head-tracking to produce surround sound. Then there is Sony’s all-new immersive sound format, 360 Reality Audio, that brings 3D effects to your music. Firmware updates can be pushed through in the app as well. Here is where you’ll find a customizable EQ with multiple music presets, adjustable ambient levels, Adaptive Sound Control, NC Optimizer, and Sound Position Control to emphasize sound in different positions. Blaring sounds (e.g., blow horns, sirens, loud sound systems) do creep onto the soundscape, but unless happening a few feet away, they aren’t distracting enough to pull you away from whatever is playing.Īt the center of functionality is the Sony Headphones Connect app, which is compatible with most of Sony’s wireless headphones and earbuds. Being on the ground is just as rewarding with either headphone putting a kibosh on mid-low frequencies while minimizing loud noises at an incredibly high level. Pre-pandemic, the WH-1000XM3 and WH-1000XM4 accompanied us on many flights, so we can attest to how great Sony’s noise-cancelling technology performs in the air you’ll barely hear only the low-end rumble on an airplane. The other is Atmospheric Pressure Optimization that adjusts pressure and sound delivery accordingly to altitude. One of them is NC Optimizer, which optimizes ANC based on various factors such as the shape of your ears, hairstyle, eyewear presence, and the ambient noise around you. Even better is that Sony programmed special modes to customize noise cancellation on the fly. Sony’s HD Noise Cancelling Processor QN1 chip with Dual Noise Sensor technology and feedforward mics do a fantastic job of analyzing and filtering out external sound. Only those with detailed hearing will notice a difference in ANC performance on either model.
