Recently, the birthday wife gave fruit 7P as a birthday gift. It was a pleasant surprise but the troubles came... Because the 7-series began to cancel the 3.5mm headphone port. The earphone used originally had to be connected to the head to use it. It was very inconvenient. So think of a solution. Like the majority of digital enthusiasts, the first thought is Bluetooth. Since I have heard that Bluetooth has an impact on sound quality (and fruit does not support LDAC), I initially rejected the Bluetooth solution. At this time suddenly remembered a netizen's one text, introduced the ELECOM amp, small and Lighting interface line, is simply born for the fruit 7, so immediately decided to start. After buying the experience, the effect was really good, but it took 2 days to work to get a face. The metropolitan subway was very crowded. Because of the thicker wires, it was often brought to a halt. One day I finally couldn't stand it or return to Bluetooth.... (A pile of nonsense finally entered the topic)
Actually, Dafa, the Bluetooth receiver, began to pay attention since it was released, but it was finally confirmed that the cable connecting the headset could not be stored. It was quite disappointing and there was a feeling of semi-finished products (you can refer to LG's collar 900), but the one that was on hand was a pass. After tangled or start it...

Official introduction: The MUC-M2BT1 connector is equipped with a Bluetooth receiver module. Using it in combination with a Sony In-Ear Headphone 1, you can instantly upgrade your favorite headset to a wireless headset. The neck hanging method reduces the trouble of being twisted by the headphone cord, so that your overall dress is more refreshing and capable. The NFC one-touch function makes it easier to connect your headphones, player and mobile phone. LDAC technology is supported to allow you to enjoy high-quality music wirelessly. (Compatible with SBC, AAC and APTX)
After replacing the headphones, I made a simple audition. Since I am not professional, I simply say the following:
Advantages: First, wear comfortable, and the other because the device has some understanding before starting, the thrust is not, so specially selected a better push the headset, only 300AP on hand, did not listen to carefully AB, the feeling and the cable sound quality is not much difference (This is better than 300AP.) Personally feel that the commuter used this sound quality enough (conservatively estimated to have 90% of the original sound quality it is on the fruit machine feel in the case of LDAC personally feel at least 95 % In fact, I really did not hear how much difference ......); Second, Bluetooth, no wrap around the worries, this is the biggest advantage of it; Finally, the receiver supports cut song, adjust the volume and call, the general function of it Have.
Disadvantages: As mentioned in the previous paragraph, it is regrettable that wire rod storage (without telescoping mechanism) is not supported. Secondly, the price is slightly higher. Finally, it is considered to be the outlook. Nowadays, Dafa noise reduction products are frequent, and it is hoped that the next receiver can Plus noise reduction.
PS300AP is a very controversial headset. People like it very much. People who don’t like it spray it with nothing. It is one of the few earphones that I’ve used for this impulse consumer. . I would like to name it right now. Actually, 300AP is not as bad as some fans say. It's just an ordinary headset that focuses on mid-low frequencies, while it focuses on mid-high frequencies and listens to BANDARI's music especially!
