Transcending AirPods Pro, Sony brand new noise reduction headset: Sony CXD90050 chip blessing, solid materials, exquisite circuit design

Two years later, Sony has finally released WI-1000X lavalier wireless noise canceling headphones successor Sony WI-1000XM2, the appearance has been redesigned, the main use of headphones silicone skin-friendly material, support wire, retained the 3.5mm audio Interface; at the same time, partial design elements of WF-1000XM3 are fused in the design. Let's take a dismantling to see what is the internal circuit solution? Directly look at the PCB motherboard after dismantling, the PCB design is superb, and two metal contacts of the Bluetooth antenna. TI BQ27421 power monitoring chip, for monitoring the battery, its built-in regulator and sampling resistor, compact and easy to use. TI BQ27421 details. Screen L7B F9F 10 IC. Silk print 9b8 05 IC. MTK Liaotai MT6388P power management chip, right side is three inductance. Silk print Q128FWY memory chip. TI BQ24308 Charger distal protection IC, and supports programmable overvoltage and overcurrent protection. Sony CXD90050, this IC particles is developed by Sony HD QN1 noise reduction processor, using the 32-bit audio signal processing technology, integrated in the power amplifier so that the analog and digital to analog converter QN1 headphone achieve excellent signal to noise ratio and low distortion Bring outstanding sound quality performance. SONY Sony WI-1000XM2 using MTK (up network) MT2811 platform approach, this chip is mounted MCSync TWS double Bluetooth mechanism, support the master experience seamless connection from the exchange, and Bluetooth 5.0, Ultra low power functions, Google Bisto voice Assistant functions. It is understood that SONY Sony WF-1000XM3 is the same chip, MT2811 is a high-performance chip in the AB155X platform series. Summarize Sony Sony Wi-1000XM2 neck-like wireless noise-saving headphones use silicone material, freely folded, headphones are magnetic design, overall, more portable, greater than the previous generation Wi-1000X, but internal also before and after the double ring and iron mixed microphone feedback structure of the driving unit, the presence or absence of specific configuration temporarily clear differences; a charging interface upgrades to Type-C; adds remote control function, which has a separate call microphone, and a custom buttons, more convenient to use. Sony Sony Wi-1000XM2 adopts Sony HD noise reduction processor QN1 and MTK (Garid) MT2811 platform scheme, combined with WH-1000xm3 head-denowd Bluetooth headset and WF-1000XM3 true wireless noise-cutting headphones; neck Both the motherboard on both sides of the hanging structure are fixed, and there are two layers of cover protection outside, and the overall work is excellent.
