## Description

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.

Review: Great for doing vocal exercises - I was looking for a device or a booth that would allow me to sing without disturbing my neighbours. The insulation in my apartment is horrible, so I needed something that would at least decrease half of the decibels. I've tested it and recorded myself using the Beltbox and singing without the Beltbox, and I'm very impressed with how little you can hear. I think my neighbours can probably still hear me vaguely at a distance, but definitely much less than without using the Beltbox. One little thing that bothered me is that the strap pushes the Beltbox so closely on your face, that I find it hard to breathe. I tried to adjust the strap, but even then it's still uncomfortable. I therefore don't use the strap. I still give it 5 stars, because I think it's great value for your money. It's easy to use and it fits in your bag.
Review: Best buy I’ve ever made - The best purchase I’ve ever made. When buying I thought it was a bit pricey but it is worth every single penny. Super easy to clean and was so shocked by how much it dampens the voice during warm up and belting. Really good quality, just so so happy with this product. I wish I had bought it sooner.

### ⭐⭐⭐⭐⭐ Great for doing vocal exercises
*by C***A on 30 August 2019*

I was looking for a device or a booth that would allow me to sing without disturbing my neighbours. The insulation in my apartment is horrible, so I needed something that would at least decrease half of the decibels. I've tested it and recorded myself using the Beltbox and singing without the Beltbox, and I'm very impressed with how little you can hear. I think my neighbours can probably still hear me vaguely at a distance, but definitely much less than without using the Beltbox. One little thing that bothered me is that the strap pushes the Beltbox so closely on your face, that I find it hard to breathe. I tried to adjust the strap, but even then it's still uncomfortable. I therefore don't use the strap. I still give it 5 stars, because I think it's great value for your money. It's easy to use and it fits in your bag.

### ⭐⭐⭐⭐⭐ Best buy I’ve ever made
*by H***H on 29 December 2025*

The best purchase I’ve ever made. When buying I thought it was a bit pricey but it is worth every single penny. Super easy to clean and was so shocked by how much it dampens the voice during warm up and belting. Really good quality, just so so happy with this product. I wish I had bought it sooner.

### ⭐⭐⭐⭐ Good Product Although Expensive
*by N***M on 25 August 2025*

The first thing to say is that this product is really expensive for what it is. However the reviews for the next level of price weren't great so I went for the Beltbox. The most important thing to say is that it does seem to reduce the volume significantly. So the main purpose appears to be met. I'm a guitarist so using the Beltbox with the strap for learning new songs while playing. It's not particularly comfortable with the strap, but it does work, despite what other reviews say. One negative point is that breathing is not easy with the strap on, but you can move it slightly with the jaw to facilitate a breath. I've only had it a day though, so may need to try different adjustments to the strap. It comes with a carry-bag and cylindrical box which are snazzy but if they're adding to the cost I could do without them. Overall it does work. It's not perfect, but you're not going to get perfect without a soundproof booth. I'm happy with the purchase but would be much happier if it had cost £20 less.
