For a long time, I think wired earphones are more attractive than wireless earphones, because the former has more choices, richer appearance and styling, but all of these have changed since the author used the 5.5 inch mobile phone, because the mobile phone is too large, and with a headphone cable, it is almost uncomfortable to walk around, let alone go running and listen to music with the Galaxy Note8.

If you want to feel like a wireless headset, then you don't want to buy a wireless headset（ Because good ones are too expensive ）What should I do if I have good wired earphones at home? Then it can be solved through wireless audio receiver, and the author is also experiencing the BTR1 of FiiO recently.

appearance

The BTR1 is relatively large. The body surface is made of metal. It feels very comfortable and has a texture. It doesn't have extra weight, but it is slightly larger.

The splint is also very large, and it is more confident when it is clamped on the clothes. It should not fall out easily. One side of the body is equipped with a volume key, which is very convenient to adjust. There is a round key on the front, which is the only three keys in the BTR1. However, they have multiple roles. For example, in addition to adjusting the volume, long press of the volume key can also achieve the previous/next song, The round button can turn on/off, play/pause, answer and hang up the phone, etc., so there will be a certain learning cost, but it will take a few days to get used to its operation mode.

Wear&Use

Although BTR1 is not a very fashionable toy, it is certainly not ugly. It can be said that it is a moderate design. A huge splint behind it is much better than some similar products.

Basically, there is no problem with how you want to clip it. I tried to run on the collar, pants pocket, schoolbag, etc., but it is still stable and will not fall off. It is quite light, without any burden.

The way to use BTR1 is also very simple. Turn it on（ Long press the round key ）, and then turn on the mobile phone Bluetooth, you can see "BTR1" in the search list, click to connect, and then plug in a headset, you will be Good To Go. What's more convenient is that BTR1 also has a built-in microphone, which is particularly practical for some users who have no microphone headset. As for the call quality, it is good, and it is OK to make calls.

（ Size contrast ）

As for the endurance, BTR1 has a battery capacity of 200 mAh, which is officially claimed to be able to hold up for 8 hours. For this type of product, the author hardly worries about the endurance, because no matter how good it is, it will be OK to use it for one day. What's more, most of the time when using it, you can either go to the gym to keep fit or listen to it on the bus or subway for one or two hours at most, Plug in the power supply for charging when sleeping at night.

hear

In terms of sound quality, let's first look at the data. BTR1 is equipped with a decoding chip AK4376（ DAC with AMP ）, I believe everyone knows this audio chip very well（ A bunch of mobile phones have been used: Z17、 Meitu, R11s, etc ）The output power is also as high as 40mW. In short, such book parameters are very good, and may even be stronger than the thrust of many mobile phones.

As for the sense of hearing, I used Samsung's own AKG headset for testing, and the thrust performance was good. Even though Bluetooth was used for connection, the original quality of the headset, such as bass and voice, could also be reflected. As we all know, the audio performance of Qualcomm's Samsung flagship machine is very urgent. The thrust is not enough to make some earphones perform as they should. With a BTR1, you can enjoy music.

But for the author, what BTR1 really likes is that it can achieve a good balance between portability and performance, ensuring the original quality of headphones. Similar products, such as Xiaomi audio receiver, can not achieve this, but there is a price difference* Millet: 99 yuan; BTR1：298  element 。

In addition, we（ Official number: Love to play computer games ）We also got the MMCX interface headphone cable from FiiO, The length of 60cm is matched with our own Ripple F9 headset, which is very satisfactory both in terms of portability and sense of hearing. The author used the A/B test to experience it. First, plug the short line+F9 headset into the BTR1 to listen to one part of a song, then plug it into the handheld, and listen repeatedly. In general, the audio performance of the two methods is basically the same, However, this is not a problem, but an advantage. For Bluetooth connection, there will inevitably be some loss, no matter how much or how little, so as long as the headset can show the due standard, I think BTR1 is good.

summary

Back to the beginning of the article, there are so many people using the Big Mac mobile phones today, listening to music has become a trouble, and excellent wireless headphones are too expensive. At this time, BTR1 has the meaning of existence. It takes into account the original audio quality of wired headphones and the convenience of wireless connection. Therefore, if you want to use wireless and pursue sound quality, BTR1 will be a good choice.

The price of 298 yuan is also acceptable for most people. Although Xiaomi's audio receiver only costs 99 yuan, the principle of "pay for goods" will not change. The quality of BTR1 is obviously better.
