These two colors look gorgeous. They share the same design language with the old products. In terms of design, they are still based on wh-1000xm3. This is not a bad thing, because xm3 itself is a product widely recognized by the market.
In terms of actual sound quality, the sound of Sony wh-1000xm4 should be similar to that of its predecessors, because it uses the same 40mm driver unit, the battery life remains unchanged, and the active noise reduction plays for 30 hours. Still, Sony has added quite a few changes. First of all, the noise reduction chip is still q1n processor, but the new Bluetooth audio system chip is upgraded. It can analyze the music and the surrounding environment noise 700 times in a second. With the adjusted algorithm, this makes the wh-1000xm4 more effective in controlling the sound and intermediate frequency noise.
Xm4 has improved the previous generation's poor voice quality when making phone calls with this headset. They have added a new voice pickup technology, which can control five microphones in the headset and ensure that the signal is handled in the best way. The new speech to chat function will temporarily pause music when you start talking, and resume playing once you stop talking. Another improvement is that the headset can also be paired with two devices at the same time.
Generally speaking, we think that Sony wh-1000xm4 is an improved version of wh-1000xm3, which is also the usual practice of Sony, because they will constantly improve the areas that need to be improved, rather than drastically update the entire product design.
