Good for singers who like to practice late night in hotels
I absolutely love this product. It really comes in handy for late night, rehearsals and hotels. I don’t want to disturb everyone else while practicing for my shows very easy to clean damp. The sound really well will definitely buy another one if needed in the future I’ve recommended this to all of my singing friends.

This will revolutionize my singing practice
All my life I wanted to be a singer, but I have a serious psychological mental block about making noise. I genuinely don't know where it came from, but for literally my entire life, I've hated the idea of being loud which, unfortunately, extends to singing. I made some headway against it when I picked up the saxophone, which there's just no way to play quietly, but I still was absolutely struggling to put any power behind my voice. Before I got my Beltbox, I would struggle to hit notes in my chest voice range because I just wasn't giving myself enough breath support, so the note would get choked off before it could come out, and my head voice range extended to a strained A5 and a passable F 4. Almost immediately after I started practicing with the beltbox, because I could no longer hear myself as clearly (and the psychological notion that, neither could anyone else), I was literally instantly able to hit E5. I have never sung that high in my life, and could not believe my tuner. I had to go to my piano, play the note, and sing it to confirm. Some caveats: yes, it is difficult to breathe while wearing this thing. You may want to either hold it in your hand, or keep a hand free to move it when you breathe in otherwise, you'll start to open your mouth horizontally really wide to break the seal and inhale that way which could become a bad habit if you're not conscious of it. If you correct yourself during non beltbox practice this shouldn't be too much of an issue though. One of the criticisms I've seen online, especially on Reddit, is that it's "just a $50 pillow". Two problems with that argument though. One, a pillow ain't portable. You're not going to shove a pillow in your purse or day bag. Two, you can't strap a pillow to your face, if you want to actually see where you're going anyway. This is excellent for quiet practice while multitasking, and it honestly just looks like a very unique face mask in the post-pandemic world we live in. I'd rather someone think I'm just wearing a unique face mask while I strengthen my voice and breath control, than to hear the awful noises I'm going to be making into this thing (from the next room/next door, anyway. If someone's in the same room they are goiing to hear you. That's just how physics works). Now if you'll excuse me, I have some singing practice to get back to!

Muffles sound relatively well but doesn't stop all sound leaking
Product came on time and in relatively good condition. Muffles the sound you make with your voice but if your roommate is sensitive to noise this won't stop them from waking up. Problems can start when you wear glasses. Wearing the mask properly makes it so that its very difficult to wear glasses at the same time as the mask can ride up to your nose. Moving the mask down to accommodate means that a gap may form around the chin allowing sound to leak through. I personally solved this issue by stuffing a microfiber cloth in the chin area to plug the hole, which absorbs the sound leak. I suspect that moving the beltbox further down the face and stuffing in a cloth will solve a large portion of the complaints against the beltbox, particularly the ones addressing chinsize and the ability to move the mouth. A chemical smell will start to form in this mask if you keep it in a closed container or leave the beltbox in its full intact state overnight. To deal with the smell, its best to separate the black rubber and the red foam sections when not in use. This mask can allow you to stick a very small microphone inside it. The mike will touch your lips on occasion but this can be a way to talk to people online late at night and be less annoying to anyone in the vicinity. But once again I must emphasize that this is a dampener, not a silencer. People can still hear you, even if they can't make out what you are saying. Other than that, this product works fine. I'm not quite certain if it was worth the full price but get it on sale and save your neighbors a bit of a headache.

Quit rehearsals
Does what it says it does. Now I can vocalize without disturbing loved ones mornings.

good for amatuers, not so much for professionals
good for amatuers wanting to stretch some vocal chords and trying not to piss off neighbors. good concept, well manufactired, however, very difficult to breathe (may be a plus if you want added lung conditioning. i stuffed two steel straws in the sides for a little more airflow). also, its very tiny. i have a small face and trying to open my jaw more than 0.5" to really belt one out (which is the point, right?) just pulled the mask so far down my nose it completely cuts off any nasal capacity as well as very uncomfortable. also the strap needs to be macgyvered with extra elastic straps if u want to wear it hands free. as for its claim that theres no effect on intonation, lie. its very much like screaming into a pillow. but as just an amatuer rock singer who just needed to work on simple power notes without feeling silly and getting neighbors pissed, it definately worked for that. great for a quick vocal stretch right before hitting the stage. wish it had more room for jaw movement tho...

Does what it says!
Yk it looks really silly, but i think this is my favorite thing EVER. Obviously it doesn't cancel out all sound, but it does muffle it pretty well! Its also flexible material so you kind of have to squish it around your face - I can tell its going to be easy to over sing though but that will take time. -I will say the one thing i dont like is the plastic-y smell even after i washed it. so hopefully that goes away over time

La mascherina aderisce bene al viso, sia con la fascia che senza, sorretta da una mano. Questa seconda modalità lascia più libertà al movimento della bocca e migliora la respirazione, ma nell'altro modo si hanno le mani libere, ad esempio per reggere uno spartito. Sicuramente cantare a voce libera è assai meglio, ma in questo modo il volume sonoro viene molto smorzato e non si disturbano i vicini, specie in determinati orari. Nonostante lo smorzamento acustico, riesco a sentire bene la mia voce e, soprattutto, la corretta intonazione. Alla lunga ci si stanca un poco, soprattutto per qualche difficoltà nella respirazione, è come cantare con una mascherina ffp2. Però è un ottimo ausilio per esercitarsi in casa senza litigare col vicinato, cantando a piena voce ma con un impatto sonoro equivalente a cantare sottovoce. Costa un po' ma secondo me ne vale la pena, non è ingombrante e facilmente trasportabile per esercitarsi ovunque.

Awesome item! It has helped me immensely as a musician. It has allowed me to practise in was I couldn't have otherwise, aside from pushing my vocal strength much more than without.

Ça me semblait trop beau pour être vrai. Mais ça marche vraiment. Je recommande. Par contre, ma barbe à tendance à abîmer la partie rouge

Si estas esperando que no se escuche absolutamente nada, entonces no entendiste la función de la máscara. Es un atenuador del sonido y con ella puedes vocalizar sin restricciones en tu casa. Vale la pena a pesar del precio que creo es un poco excesivo.

It is a good idea, and the materials are good quality, however it doesn’t feel completely fine not being able to hear properly when you sing, i think being able to hear yourself while singing is a key aspect. So i would not use this item to practice singing, although is good for when you want to stretch or warm up your voice
