Review: ①軽い ②USB充電 ③ベッドマイクは痛くない ④音声はクリア 使い勝手はとても良いです。
Review: 風邪をひいて声が出なくなり、仕事で30人ほど入る部屋で話をするのに購入。 8時間ほどウエストベルトに装着しながら歩き回って使用しても、あまり重さも気にならず、声も後ろの席まで届いていたのでよかったです。 初めてポータブル拡声マイクを使用したので、他の同様商品のことは分かりませんが、操作や充電が簡単で、今まで一日中話をしていて声枯れすることも多かったので、普段から使用しようと思うくらい、便利なものがあるんですね。 多少息づかいや雑音は入りますが、賑やかな部屋では私はそこまで気にならなかったです。

風邪をひいて声が出なくなり、仕事で30人ほど入る部屋で話をするのに購入。 8時間ほどウエストベルトに装着しながら歩き回って使用しても、あまり重さも気にならず、声も後ろの席まで届いていたのでよかったです。 初めてポータブル拡声マイクを使用したので、他の同様商品のことは分かりませんが、操作や充電が簡単で、今まで一日中話をしていて声枯れすることも多かったので、普段から使用しようと思うくらい、便利なものがあるんですね。 多少息づかいや雑音は入りますが、賑やかな部屋では私はそこまで気にならなかったです。

広めの部屋、ざわついた場所で講習する際にのどが枯れるので購入。手があくのでデモストレーションもできるし、声もいい感じに届きます。色もかわいくて良いです。
