Leading technology and improved stability
I’m absolutely delighted to have discovered SereniBrain, a meditation tool that fits my needs even better than MUSE. I especially appreciate its excellent connection stability, which allows me to truly relax during my meditation sessions without any interruptions—exactly what meditation should be all about. Beyond the built-in sessions, I really love that I can use any audio I prefer to track and assess my meditation state. What’s even better is that I can do nothing at all, I simply wear the headband, turn on the meditation tracking feature, and it accurately records my brainwave data. It’s fantastic! I was pleasantly surprised to find their "Raisin Meditation" guided session, which remind me of the book An 8 week program to free yourself from depression and emotional distress. This engaging and effective mindfulness practice shows that SereniBrain is dedicated to combining meditation theory with practical guidance. I’m excited to see what future updates will bring!

Excellent design and execution
Supports meditation being more productive and interesting. Excellent device for meditation feedback. I particularly like that it alerts me when I start thinking instead of concentrating by lowering the volume. It also provides an ongoing score that can be used to compare against other sessions on a calendar and as feedback during a session. There is more indepth feedback focusing on a particular type of brainwave. There are a variety of guided meditations, guidance free meditations and a feature to monitor my meditation using my own music or guidance separate from the application. I had a problem with my first unit and customer support was very attentive.

Very accurate and reliable signal - data is depersonalized
This is an impressive instrument. As it first came on and started to triangle its signal, I reached down to scratch my leg. The graph actually reacted to my movement in real time – there was NO lag. There have been no disconnects either. A gel electrode will always beat a metal electrode. As an experienced mediator I can say the “Practice State Curve” is very accurate and responsive. More improvements are to be expected since this is a new product. I would like the option of reducing the data points on the graphs so I can get more on the screen (1/10 of a second is a lot of data). They also need to add the ability to export the data. Someone complained about no privacy and the data going to China. What in the world is China supposed to do with my data? Am I going to go on vacation to China and get interrogated over my EEG numbers? I don’t get it. The data is supposed to be depersonalized, and if it is not who cares.

Can we get more time?
I like the headband. It is comfortable enough and the program is user friendly. However my only complaint, is that it only gives you 30 minutes of biofeedback. I would like to be able to use it for training through much longer meditations.

Precise feedback, comprehensive features
I am grateful to SereniBrain for revealing the significance of real-time biofeedback in enhancing my meditation practice. Previously inconsistent and unplanned, my meditation journey has transformed with SereniBrain. It offers precise feedback that allows me to gauge my meditation state in real-time, helping me address weaknesses and improve gradually. My experience ranges from guided sessions to free practice, with daily programs providing fulfilling progression. My focus has sharpened, distractions have decreased, and I now enjoy a profound sense of inner peace. Following customer support's advice, I monitor Alpha wave trends in my meditation reports, linking them to a relaxed and alert state, which has helped me track positive changes. Additionally, the ability to easily share and export data without extra apps is a significant plus. For anyone interested in brainwave analysis and enhancing meditation discipline, SereniBrain is a reliable investment with all features available at no extra cost.

Adds incentive to meditate
The major drawback of meditation for me has always been my reluctance to practice consistently. I think this is because I become disillusioned with seeing no visible results. This headband adds a bit more incentive since it (and it's accompanying app) allows me the see whether my mind is active, relaxed or calm during each session. Pretty effortless to use; simply connect Bluetooth, set your level of difficulty, the amount of time you choose to me monitored and begin. After each session the AI offers a description and analysis of your session. Easy. Using the headband has also prompted an interest in the various brainwaves monitored. How to replicate or produce specific brainwaves to obtain desired results. Highly recommended.

It’s okay.
Kind of boring. Hard to figure out how to make it work. You just put it on and try…. But it doesn’t tell you how. You just have to figure it out. I found closing my eyes and humming worked to get a better score. I prefer to just use online meditation videos and close my eyes.

A nice meditation headband with reliable connectivity
As described, it's comfortable to wear and keeps a stable connection, which was my main reason for buying it. I have had no issues with signal loss during my sessions, and my experience has been great so far. Need to download an app to use with the headband. Before meditating, you can see your brainwave patterns on the app, which is really interesting. The app gives visual, auditory, and score-based feedback to enhance meditation. This helps me monitor and improve sessions in different ways. I'm not an expert yet, so I usually follow the guided instructions with my eyes closed. However, I plan to try meditating with my eyes open and focusing on the visuals for a new experience. I need to spend more time using it, and I look forward to developing a better meditation habit with its help, which will also benefit my neural training.

3つの電極でリアルタイムに脳波を解析してくれます。 電極は6つ付属しており、一度に3つ使用するので予備が3個あることになります。 ゲル(耐震ゲルのような)でクッション素材にはなっていますが、 出っ張っはいるため、なれるまで違和感は有ると思います。 バンドは緩めにしておくことで多少軽減できはします。 アプリは登録が必要なので、登録自体が気になる方は使用するのが難しいかもしれません。 また、詳細な解析をアプリで見る場合はデータをuploadするのに同意する必要があるようです。 脳波なので気にしなくてもいいかなとは思います。 リアルタイムは頻度が高く、12回/秒程度プロットがあり、 確かに約80ms毎のデータを取得しているようです。 Delta, Theta, Alpha, Beta, Gamma, SMRの脳波を見れるようです。 アプリには瞑想ガイドのデータがいくつも有り、 風景やサウンド、ナレーションが入っており瞑想を これから始めたい方でもやりやすいと思います。 アプリやナレーションは日本語対応しており、 ナレーションの質も高く、機械翻訳の自動音声や外国人ではなく 日本人のナレーターさんがやっているようです。 ぎこちないナレーションだと瞑想に集中できないと思うので、 違和感のまったくないナレーションというところも非常に良かったです。 目を閉じたり、開いたりするだけで結構数値が変わるので ちゃんと脳波を取っているんだなと感心しました。 また、瞑想トラッキングというところから 独自で練習したり、逆に学習や何かしらしているときの脳波も取れます。 勉強に集中できているか、思考が出来ているかみたいな使い方も出来て 瞑想以外にも活用できる点はとてもおもしろいです。 本体は多分長く使えると思うのですが、電極はゲルなので ある程度したら交換が必要かと思われますが、 レビュー時点で交換用で単品販売が見当たらないのが惜しいです。

Te cobran por la devolución y es más caro, jamás se vincula. No es funcional es una estafa.

就寝前の15分間、これを額に巻いて目を閉じるのが最近の習慣です。瞑想といっても、これまではただじっとしているだけで「これで合っているのか?」という疑問が常にありましたが、このバンドは脳波の状態をリアルタイムでスマホ画面に可視化してくれるので、自分の感覚の答え合わせができる点が気に入っています。 深呼吸をして意識を落ち着けると、画面上の数値や波形が即座に反応して変化するので、ただの我慢比べだった時間が「自分の状態を確認するゲーム」のような感覚に変わりました。バンド部分は伸縮性があり、長さを調整できるので頭のサイズに合わせて固定できます。センサーが額に直接触れる必要があるので、前髪をしっかり上げて装着するのがコツですね。 もちろん医療機器のような厳密な測定値を期待するものではありませんが、自分がリラックスできているか、集中できているかの傾向を掴むには十分な感度があります。感覚だけで行う瞑想に挫折した経験がある人には、目に見える指針として良い練習道具になるはずです。
