Review on ZTE Blade A5 2020 - 32GB, 2GB - 6.09" HD Edge-to-Edge Display, 3200mAh Battery - Dual SIM GSM Unlocked US 4G LTE (T-Mobile, AT&T, Metro, Straight Talk) - International Model (Black) by Ayden Loh ᠌

In general, for such money it's not bad, but about the sound - it's a disgrace. With its pros. The phone is narrow, comfortable to hold in your hand. There is an LED indicator - you can find out about notifications without turning on the phone. Most competitors save on this. It is possible to set the screen to turn on by double tap (configurable in the gestures section). A very good thing, there is no need to poke a button every time. As I understand it, this is also missing in many modern phones. As I understand it, battery consumption increases, but according to a very rough estimate - no more than 3-5% per day. Has cons: I tested the headphone output using the well-known RMAA program. Delivered from the Market "Simple player: music player" (developer of Simple Mobile Tools). There are no equalizers in this player, it plays as it is. I connected the phone to the linear audio input of the computer (added headphones to the load so that the phone outputs sound through the 3.5 connector). The result of Frequency Response (multitone) and Frequency Response & THD (Swept Sine) is in the attached images. On the charts: loop - pattern when lin. the output is inserted into the line. input; zte - headphone output from ZTE A5 2022; asus - for the sake of interest, I connected another phone by installing the same program in it; zte-vhm314 - took sound from the Bluetooth receiver vhm314, which was played from the ZTE A5 2022. The results show that it is the headphone output that has a dip of -30 dB at low frequencies. On Bluetooth, the sound goes quite smooth. ZTE representatives state that this phone has no sound enhancements. If this were the case, the frequency response would be close to flat. In fact, the sound is specially mutilated. As far as I understand, this is called sabotage.
