OMG! Talk about being able to run scales, switching registers, dynamics, even character voices without the worry of haters stealing your ideas as you work them out. Also, and if need be, one can improve their technique and breathing at the same time. It feels comfortable to use with or without the head strap for hands-free use. The quality is Great and worth the money, it is compact, so it fits well in your shoulder bag. One of the first things I noticed was that the sound quality was not lost when I sang both hard (chest register) or soft (head register). For anyone understanding the break point between registers, the area we don't like others to hear when we are warming up and/or practicing, get this. I use this with my Breather Fit and I recommend them being purchased together as a must-have, for anyone reading this and serious about building for themselves a Vocalist toolbox. Side note: Don't forget to hydrate, avoid sweets, dairy and rest your vocal cords when they are not needed. Your voice is just as if not more important than a piano and/or saxophone when it comes to music. Thank You Read more

Does exactly as advertised - comfortably dampens sound to about 35% of the original volume. I'm a mezzo soprano, but I'm working on expanding my higher range. Unfortunately, I wasn't practicing enough between lessons because I didn't want to bug anyone. This gadget will help me rehearse without annoying my family and my neighbors in the adjacent townhomes. It is lightweight, portable, and washable. This is an excellent find! Read more

OK, I bought this kind of out of desperation. I had some bad coughing spells for about a week and I lost my ability to reach certain notes. I just squeak now so I needed something to practice with and this really seems to work pretty good. I’m not sure if it’s going to help me get my voice back but now I can Try without having your neighbors call the police. Read more

I really like the convenience of being able to grab it and practice when I can’t be super loud. I’m not a fan of how small this version is, though. I was hoping to get the 2.0, but they haven’t had it in stock, and I feel like I can’t release my jaw properly and still keep the sound to a minimum. The actual dampening of the sound is very effective for what it’s worth. Read more

"product": "Whether you're a singer, actor, or performer, BELTBOX 3.0 offers a great way to warm up your voice at full volume, without disturbing those around you. Designed as a portable vocal dampener, BELTBOX reduces your voice output by up to 30 decibels, allowing you to rehearse confidently, discreetly, and on your own terms. Made with advanced sound-dampening materials, BELTBOX maintains vocal clarity so you can still hear your pitch and tone, while others hear far less. It's ideal for use in shared spaces, backstage, at home, or on the go. This latest version features a removable, hands-free strap so you can warm up while practising choreography, playing an instrument, or preparing for a scene. It also comes with a soft cloth carry bag to keep your vocal kit neatly together. Fully waterproof and easy to clean, BELTBOX 3.0 is even safe to use in the shower, making it ideal for steam-enhanced vocal warm-ups. Compact, discreet, and effective, it’s a must-have tool for any performer serious about vocal care and preparation. Recommended for ages 13 and up. Dry use or steam use only, not for submersion.",
