It cool you can hear music if you put it on your eardrums. I wear it at work and they don't know muhahaha

1) Doesnt work unless you put the neck cable literaly over your ears and even then the sound was soo poor and low that I could only understand 1 out of 4 every words my gf was saying. Music is not an option cus you will hear echos from an alien space ship.2) POOR DESIGN / CHEAP MATERIALS:The box wont fully seal, the battery terminals that clips on the 9V battery almost broke when I was trying to get them off the first and only time I used it.3) It overheated 1 mins after use, then 3 mins later it was soo hot to the point the whole living roomstarted to smell like burnt plastic. No fumes obsereved or melting but the heat and smell was enough indicative that fire is immenent if I continue to use it for another 5 mins.DO NOT BUY, THIS IS A SCAM.I returned mine the very next day, dont waste your time because you will end up doing the same thing unless I got a really bad package, but even if thats the case, I would buy this product just because of the poor design and cheap workmanship.Good luck.

Havent tested as just revived and there are no earpieces included

It is too small, can hear clearly but only thing, it could fall out anytime if u didn’t place it properly. I love it so much, easy peasy to use..

長々書きます |ﾟДﾟ)))職場で使う為に購入(青歯イヤホンで怒られた)音質はお世辞にも良いとは言えません、耳の中で町内放送が流れてる様な感じ。GBやSFC等のBGM、歌詞がないサントラとかならまだ聴けるレベルです。使い方としては鼓膜に当たる(音がする)まで金属を入れ(落とし)込む感じです。異物感が半端ないですし、1時間に1回くらい謎の痛みが走ります(個人差？)。あと電池が付属してないのでエボルタ君買ったんですけど1日(8時間)保たないです。いや使えなくは無いんですが電池の容量が減ってくると音量がめちゃくちゃ下がります。8時から使って17時前には虫の息です。なので私はボックスタイプの充電池を別途購入しました。あと磁石で耳の中から取る際ですが、磁石を挟み込んだ上で耳の穴に突っ込めるピンセットがあった方がいいです。磁力が強いのでゆっくりと差し込まないと鼓膜で暴れて大変な事になります(1敗)長々書きましたがデメリットとリスクを知って頂いた上で自己責任でご購入を。まぁぶっちゃけゴミに等しいですが私はコレしか選択肢がないので神商品です(｀°ω°')
