You can see how to automatically connect with iPhone simply by removing EARIN from the capsule by looking at the following movie.

How the World's Smallest Wireless Earphone "EARIN" Automatically Connects to iPhone - YouTube


The parcel of EARIN that arrived contained something like a big box, a small box, a card case.


Try opening a lid closed with a big box magnet ......


There was a set of EARIN inside.


On the back of the lid there is a simple usage method written, pears like the instructions are not. Simple design as earphone.


A charging capsule that charges two earphones with an earphone with the front as the EARIN main body.


If you bring it in your hand like this, there is no cable connecting the left and right. The size is 14.5 mm × 20 mm, which shows that it is a very small earphone. The playback frequency band is 20 to 20 kHz, and the sensitivity is 105 dB (SPL + - 2 dB).


It has a golden mark and it is also a terminal for charging. Each equipped with a 60 mAh battery, can be charged to full tone in 70 minutes, playable in stereo for 2 hours 50 minutes.


You can distinguish between right and left by 'L' or 'R'.


As you can see from the side it is like this, you can see that it is a bit inclined to the shape of the ear.


In addition to not being slippery, it has grooves attached to the part pinched by hand, it also makes it possible to attach a special anti-slip grip.


Weight is only 7 g with right and left unit with ear pad.


Pocket size which can hold the charging capsule with one hand.


There is a Micro - USB socket for charging at the top. I was wondering if it is an "exclusive type charging plug?" Because its shape is distorted, but it is confirmed that it is possible to charge with a commercially available Micro - USB cable with Micro - USB cable. There were no inconveniences such as difficulty inserting plugs, so for the moment there is no problem.


When the head is pulled, the storage part with the terminal appears "Shuko" and emerges with a light sound that makes the near future feel.


The appearance of removing the earphone from the charging capsule can be seen from the following movie.

The charging capsule in the state where the earphone was not stored was 41 g in actual size. Even with the earphone, it is less than 50 g, it seems to be able to carry without feeling stress.


It is like this when the earphone is stored. If terminals are in contact with each other, fine adjustment of position is unnecessary and it is OK if it is pushed in.


When closing the lid, it becomes the size of the original pocket and it can be carried as it is. Built-in 600 mAh battery, you can charge earphone without USB cable. The LED indicator lights red while charging (storing).


Charging capsule Built-in battery can be charged with USB cable, and near the plug insertion port lights red during charging. If the LED turns green as shown below, you can see that the battery is fully charged.


When opening a long thin box that was in a big box ... ...


Inside is a micro-USB cable for charging the charging capsule and an ear pad called earbud called the stabilizer, ear pad.


Inside the card case was a letter of thanks to the investor and a warranty card.


Another small box contained three ear pads. There are two ear pads, two in total, large and small.


The ear pad is COMPLY (Compliance).


"Memory form" of the original material which fits to the shape of the ear is used.


When installed it is like this. It is low rebound and it fits with your fingers and shrinks, and it will swell to the perfect size when wearing it in your ear. It's sweat-proof and waterproof, so even if you get wet with your earphones and water, it's OK to wash the ear pads even if it gets dirty.


I tried using EARIN
So, to actually use EARIN, you need a Bluetooth connection.


There is no Bluetooth connection button etc, and by taking out the earphone stored in EARIN, it is ready to connect. Since it connects with iPhone 5s this time, taking out EARIN with iPhone 5s' Bluetooth turned on ... ....


EARIN was detected on the Bluetooth connection screen of iPhone 5s. Pairing is completed just by tapping "EARIN L" item. To unlock it manually from the iPhone, or store the EARIN in the capsule OK. From next time on, if you remove the earphone from the capsule, it will be connected automatically with the connected device in the vicinity. Because there is no pairing code etc., when you take out from a capsule, anyone can connect, but because it is kept in a capsule when not in use it may not be connected without permission to others.


That's why I tried wearing it on my ear. External noise cutoff rate is considerably high, and wearing it makes it difficult to hear people 's voice as well as noise. I hardly feel the weight in my ears.


When I used it replacing it with a wired earphone I always use when commuting or going out, when I thought "Listen to music" and take out the earphone from the capsule, it is connected to the terminal by the time it is attached to the ear , I was able to hear the music smoothly.


If you use only while walking, it seems that it will not come off with low resilience of the ear pad, but when you use it for exercise etc., if you install the stabilizer as follows, the part called "concha squirrel" It will be harder to come off.


When you attach the EARIN to your ear with a stabilizer attached, it looks like this. Because the earphone is fixed more firmly, it is the best when exercising such as a gym. I actually tried using EARIN while using a running machine, but there was no worry that it would come off. Also, because there is no cable, it is very convenient that exercise is safe even if you keep wearing all the time.


When using for a total of 4 days, it is enough to use batteries for commuting, etc. It is very useful to be able to automatically connect Bluetooth without touching the smartphone you connect. However, there were times when neck was necessary to select smartphones for music selection and volume adjustment, and sometimes automatic connection failed occasionally. If you fail to connect, you will have to manually reconnect from the Bluetooth setting of the terminal, or take out the earphones in the capsule and take out the earphones that will not be sounded on crowded trains that can not move Also.

Also, at the time of incoming calls, no sound is output from the earphone, so unfortunately it is impossible to hear the voice of the other party unless you remove the earphone. Since the feeling of use as "earphone without cable" was exceptionally good, if "connection failure" and "voice output of the phone" were improved, it was a product that could be used stress free.
