Good product

Compact, with Japanese manuals also easy to operate. When a private pouch is attached and it is not used on weekdays it is stored comfortably. Sound quality is also quite good, COSPA is a good recommendation earphone.

Easy to use.

I was thankful that the case was included, but I lost each case ... It was easy to use, so I bought it again.

Value for Money

It is stylish in appearance, and there is no code that catches on clothes, it is perfect wireless, comfortable. The sound quality is not the feeling that forced the bass to be heard but I think that it is good for POPS type music etc. because all the sound ranges are well-balanced. Pairing is easy and it is convenient because it shows the left and right channels by voice. It also seems that there is nothing dissatisfied with everyday use because there is still sufficient charge remaining in round-trip commuter time and + alpha time for round-trip usable time. The attached case also comes with a solid one, and there are two necessary charging cables and it certainly means a certain meaning. Even if the volume was maximized, I made one star minus with the hope that it was somewhat unsatisfactory to me and hopefully that it would have been a little bigger earpiece.

Good sound quality

Small and cute, it is convenient to do various operations with one button design. Earphones of both ears were separately used, it was amazing to be able to use it independently, it was also very good for doing jobs and jogging etc.

Small and cute. ♥. ゚. ゚.. ♥. ゚ ♡ ゚ ·. ♥.

It looks small and pretty, the size as much as a fingertip really matters! Fashionable because you can connect with wireless! It is good to listen, I can use it on only one side, I think that it is good to have a Japanese manual. I just bought it, so I use it without problems. And a hot sky store touch panel? I purchased it with formula vr goggles. Because recently is in fashion, I purchased it because I was a bit worried because the structure was different from others, but I was glad I bought it! It is perfect if you use it in combination with this wireless earphone. It was a wonderful shopping for the time being! It is five stars.

I use one ear alternately in the car.

I ordered it on July 13, 2017 and just two months have elapsed, so I will be using it comfortably so I will review it. When opening the box, it was in a cute arrangement like a panda's eyes, inside a black sponge that it cut out. At first glance I did not know which one was right and which one was right but when I tried to link the ears according to the attached Japanese instruction manual, an announcement such as "left channel" "light channel" entered, You can see either the left or the right. It is also attached to the left and right, but since the comfort is slightly different, it is better for the left to use the left and right for the right to better fit the ear. When I set it in stereo, I felt that the sound quality was quite treble and bass lacking in my case, I thought clear sound quality was suitable for hands-free calling. Perhaps changing the earpiece so that it matches my ear will change the sound quality. Actually, if you read the review of the other person, it is said that the bass frequently appeared and it got a good sound quality if you changed to a urethane made earpiece. In my case, I installed a smartphone stand at the air conditioning outlet of the car, wearing this earphone with only one ear, so that when you receive a call, turn on the power while driving so that you can exit with a single button. Mike is quite excelent, it seems that there is almost no noise and a clear voice is reaching to the other party. Also, when you double-click the button, there is a function that will be redialed at the last party you hooked, which is very handy. As soon as the left ear announces "Low battery, Please charge.", It will soon run out of batteries so remove the earphones and turn on the power with the other right ear ear earphone on the right ear while stepping the car It is patchy (^ ^) And it charges by connecting MicroUSB to the earphone for the left ear which has run out of battery when waiting for the signal. The red lamp lights up while charging and it changes to blue when it is fully charged, so it is easy to understand. With the stereo setting, you can not use one ear one by one. Once you remove the smartphone's Bluetooth connection information, once you pair with one ear, turn off the power, then pair the other earphone, so that "HS - R3" is displayed on the smartphone. After that, it turns "Pairing Successful" automatically when you turn on the power of either the right earphone or the left earphone. If it is a small supermarket or convenience store, you can go to the store with a smartphone placed in the parking lot car and go to the phone with an earphone. As expected, the phone calls are intermittent and severe, so we will go out of the store and speak, but it is appreciated to be able to answer the phone by incoming call. As I get far away from or approaching the car, it is interesting to repeat "Disconnected" and "Connected" automatically, so I sometimes play but surprisingly it was OK even if I went far. Reconnecting is very smooth even if it runs out. If we mention the difficulty of this product, is it likely that it will fall off from the ear due to the absence of the code? I think that there is a high probability of dropping while running as jogging something. I am using it for hands-free calling in the car so there is no problem at all. Depending on the regulations of each prefecture, attachment of the earphone during driving will be subject to crackdown, so it seems best to check with the nearest police station. It is necessary to investigate not only the vicinity of home but also the information of the travel destination (other prefecture) etc, but if it is only one ear, it will hear the sound of the surroundings such as the siren and the horn of the emergency vehicle without any trouble so if there are many cases of safe It is. (Net information) Control Prior to that, it is quite dangerous to close both ears with earphones while driving. Also, the most notable thing (I like it, w, many people dislike?) The volume of the announcement is quite small and discreet. Although I have several Bluetooth speakers and Bluetooth earphones, there are certainly many feeling that the announcement in English is too big, but in this model the volume of the announcement is small and it can be likable (^ ^) For the support I asked how to use it several times, but I kindly and accurately answered. Thank you very much.
