According to the description of @勝白巴吥, in early June this year, I went to the Sony store in Guangzhou and planned to buy Sony HT-A9 wireless speakers. This product is connected wirelessly, and 4 speakers can simulate a 7.1.4-channel surround sound effect.
Sony’s official website shows that the HT-A9 can achieve flexible placement, wireless connection, and automatic sound field optimization. The price is 14,990 yuan, which is quite expensive.
But he found in the store that this product was connected to two wires, one of which was a power cord. As for the other line, the clerk first said “that’s also a power line”, and later changed it to “it’s a line that makes the signal better.”
He found that the retail version of the Sony HT-A9 has only one power port and cannot connect to the second cable. This cable is a special version of Sony’s official modification, the wired version of the wireless audio. In order to stabilize the audio signal, if it is simply wireless, the official can’t solve the problem that the sound will be intermittent. They can only use a cable in private to deceive consumers and pretend that the effect is good.
Some netizens also said that they encountered the same problem, “I went to the official flagship store in Shenzhen and found that they were connected by cable at the scene. I was really drunk. I don’t know if I don’t ask, I will tell you if I ask.”
In addition, Sina Technology found that some media also pointed out in the evaluation that the Sony home theater system HT-A9 national version has many problems, but the price is extremely high.
The evaluation also mentioned the serious problem of disconnection. “The sound is intermittent due to signal problems, which seriously affects normal use.” In addition, after-sales respond negatively, contact customer service to respond to the problem, it is difficult to get a response for a long time, unable to provide effective measures, and even try to deny the problem, refusing to repair, replace or return the goods.
