“【PHILIPSとの比較】効果は間違いないが人を選ぶ。必要充分な機能あり、過度なホワイトニング期待は禁物【PHILIPSとの比較】効果は間違いないが人を選ぶ。必要充分な機能あり、過度なホワイトニング期待は禁物: 手磨きからステップアップしたい最初の1本に最適なエントリーモデル。実際に自分が使用した他社大手の「フィリップス(ソニッケアー)」との比較と、注意点をまとめました。【私の電動歯ブラシ歴・タイプ】乗り換えのきっかけ: 歯の着色や裏の歯石が気になったのと、歯磨き時間を短縮したいため。使用歴: 電動歯ブラシ歴は約4年(ソニッケアー3年 ➔ 現在こちらのiO2へ移行)。口のサイズ: 標準的なタイプです。【フィリップス vs ブラウン】ライバル機であるフィリップス(音波水流)と比較すると、明確な違いがあります。磨き心地(ブラウンが良い):フィリップスが優しい振動なのに対し、ブラウンは「物理的にブラシが回転」します。このパワーの恩恵は大きく、磨いた後の「ツルツル感」やしっかり磨けた効果は圧倒的に感じやすいです。サイズ感(フィリップスが良い):ブラウンはヘッドが大きく、ブラシの下(口に入る軸の部分)も総じて太めです。最初は口の中に大きな異物が入ってくる感覚があり、大きく口を開けて磨く必要があります。口が小さめの女性や子供には、細身なフィリップスの方が取り回しが良いと感じます。【実際に使って感じたメリット・デメリット】◎ メリット必要十分な基本機能: タイマーや圧力センサー、日常使いには十分すぎるバッテリー持ち(※ただし冬場は著しく充電持ちが低下しました)など、シンプルで扱いやすいです。上位モデルのような多機能さはありませんが、「まずは電動を試したい」という人には手頃で最高の入門機。色んな機能があっても結局毎回使わないと思います。△ デメリットと解決策歯と歯茎の間のザラつきが気になる: 表面はツルツルになりますが、ブラシ形状のせいか歯間は少し苦手な印象。あらかじめマウスウォッシュ等で汚れを浮かせたり、フロスとの併用がおすすめです。奥歯がやや磨きづらい: iO2は柄が少し短いように感じるため、奥まで突っ込むとブラシの境目が口元に当たり、慣れが必要です。お手入れの衛生面: iO2は本体の溝部分の通気性が悪く、拭き取りにくい箇所があります。水垢や菌が繁殖しやすそうなので、こまめな乾燥が必要です。正直、フィリップスより汚れが溜まりやすいと感じます。【※ホワイトニング効果について※】タイトルにも書きましたが、電動だからといって特段これ単体で「歯が白くなった」とは感じませんでした。白い歯を目指す方は過度な期待は禁物です。【どういう人に合いそうか?(結論)】おすすめな方: 「取り回しの軽さ」より、とにかく「物理的な力でしっかり歯垢を落とし、ツルツル感を実感したい」という方。おすすめできない方: 口腔が小さめな方や、細身で軽い操作感、歯茎への優しさを最優先にしたい方。多機能な上位機種を買う前に、自分の好みが「回転式」か「音波式」かを見極めるためのエントリー機として、非常にコストパフォーマンスが高い一品です!!参考になれば嬉しいです。”
“Satisfaction with Cleaning Power: I had been using a Panasonic electric toothbrush, but I purchased this one based on my dentist's recommendation. I was surprised by the difference in cleaning power. The dedicated app is also well designed, so I recommend using this product. However, the cost of the refills is a bit concerning, but I think it's a very good product.”
“歯間が磨けない: 歯の表面はツルツルに磨けるが、歯間は綺麗に磨けないので後から手で磨いています。未来電動歯ブラシはブラシを交換しスイッチひとつで横磨きの電動に切り替われば良いのに…。横磨きの電動も購入し2台持ちは場所も要るしコストもかかるので残念です。”

“Delicate Movement: The motion is speedy, incredibly fast, and very precise. This is my third one, and the battery life after charging is long! I've been using Braun for thirty years, and this time it's the iO. It's definitely more delicate, faster, and gentler compared to Oral-B, which is wonderful! The brush design is also very innovative and good.🙋♂️”
“コスパが最高⁉️コスパが最高⁉️: ★全体の質感、作りは良いです。★充電は軽くはありませんが、グリップ部分は持ちやすく、握りやすいです。★歯ブラシを歯に当てた印象は良いです。痛みや違和感は無く、歯並びの悪い自分でもクリーニング性能は良いです。★歯ブラシを強く当て過ぎると、バイブレーションとランプで知らせてくれるのは便利です。★充電器に若干入りにくい感じはしますが、問題無いです。充電器は専用品なので、USBでは無くコンセントタイプです。▲替えの歯ブラシがありません。”

“Experience the ultimate evolution from Pro to IO series! After using the Pro 1000 for 9 years and 4 months, I decided to replace my electric toothbrush. Before buying this, I thought I would try a trendy new Japanese brand that was on sale, but after one use, I felt it was lacking and gave it to my sister (it wasn't a bad product, just not to my taste). So, I returned to Braun, feeling guilty for straying, and purchased this product which was nearly half off during a sale. Here’s a catch! This is the IO series, which has different specifications from the Pro series I was used to. The replacement brushes are not compatible, and since I had a lot of old brushes left, I was shocked and thought, 'I messed up!' However, I decided to accept the new specifications since they have evolved. It arrived today, and my first impression? The box is stylish (laughs). It comes in a case that exudes a sense of weightiness, unlike any electric toothbrush I've seen. As for the important part, the user experience is... amazing! It features a linear magnetic system for vibrations, utilizing magnetic power. Compared to the Pro series I used before, it has improved quietness while still providing a solid brushing experience! After brushing, my teeth felt smooth. This is just my first use, so I might be jumping the gun, but I’m very satisfied! For those considering a purchase, here are a couple of points to note: 1) The replacement brushes are significantly more expensive than those for the Pro series. The official ones are over 1000 yen, while you can find compatible ones for around 300 yen, but the old brushes were about 100 yen for compatible ones, so this is a bit pricey. I don’t think it’s a huge deal, though... 2) This might be because it’s an Amazon exclusive version, but it does not have the Bluetooth smartphone app connectivity feature. I tried several times, but it seems the exclusive version is made differently. *Update* It seems the IO2 does not have Bluetooth connectivity at all. I apologize for the oversight. Update 2026/4/29 3) After using it for a few days, the only point I found concerning is that while it has a pressure sensor, the light indicator is too small to notice unless you’re staring at it while brushing (it lights up red). If you upgrade to the IO4 or IO5, the ring at the base of the replacement brush lights up according to the pressure applied, so if you’re looking for that feature, you might want to invest in a higher grade model. I’m fine with just being able to brush well, so the entry model is sufficient for me... but the price difference can be two to three times during sales. As I continue to use it, I’ll update if I notice anything else. I hope this is helpful!”
“シンプルで使いやすい。必要十分な電動歯ブラシです: 初めてでも使いやすい電動歯ブラシだと思います。操作もシンプルで、毎日の歯磨きに取り入れやすいです。手磨きより短時間でしっかり磨けている感じがあり、磨いた後は歯がつるっとします。上位モデルのような多機能さを求める人には少し物足りないかもしれませんが、普段使いならこれくらいで十分だと思いました。ブラウンの替えブラシが使える安心感もあります。特別に感動するほどではないですが、ちゃんと仕事をしてくれる商品です。価格とのバランスを考えても悪くなく、電動歯ブラシをシンプルに使いたい人にはちょうど良いと思います。”

“It has the advantage of being able to choose the polishing level and can be polished beautifully: I use it every day. I like that I can choose my preferred polishing level, and it stops after 5 minutes, which is great. I think it can polish beautifully.”
