They work great on acoustic instruments like guitars and drums, capturing clear, resonant sounds with minimal distortion.• Perfect for DIY Projects: With 10 discs included, this pack offers a lot of flexibility for DIYers. I’ve used them to create drum triggers and pickups for CBG guitars, and they’re perfect for experimenting with different placements and configurations.• Sturdy Build and Quality Wires: The 3.94-inch wires are just the right length for easy setup, and they seem durable enough to hold up during repeated use. The discs themselves feel well-made and have handled soldering and installation without any issues.• Affordable: Given the quality, you get great value here, especially with 10 in the pack.Cons:• May Require Some Customization: Depending on your setup, you might need to add foam or adhesive backing for better sound isolation. Not a big deal, but something to keep in mind.Overall, these piezo discs have been a fantastic addition to my toolkit. They’re versatile, well-built, and work exactly as advertised. Highly recommended for anyone looking to experiment with contact microphones or DIY acoustic pickups! ### ⭐⭐⭐⭐⭐ Cheap but the packaging is very lacking *by on Reviewed in the United States September 12, 2022* These things are fragile, I was shocked to find that they were shipped in a ziplock bag rather than a box. In my case they were all in good shape but it really wouldn't take much to destroy them in shipping. I personally use these for auto bed leveling on my 3d printer and these work well for that purpose. The wires are a bit lacking but if you're careful and don't overheat the ceramic it's easy enough to solder thicker wires. ### ⭐⭐⭐⭐ Work good. Better if you glue the solder so they don't break *by on Reviewed in the United States January 28, 2026* They work. But if you are using these for drums, well, I would do this for any application, put a drop of hot glue on the soldered wires. They break right there. Once I started using hot glue they did better. The wires are super thin! ## Frequently Bought Together - YQBOOM 12Pcs 27mm Piezo Discs with Leads Mic Drum Trigger Acoustic Pickup CBG Guitar - BQLZR 28x20mm Drum Trigger with Adhesive Percussion Instrument Parts Pack of 5 --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.om/products/93843254-20mm-piezo-disc-transducer-contact-microphone-trigger-sound-sensor](https://www.desertcart.com.om/products/93843254-20mm-piezo-disc-transducer-contact-microphone-trigger-sound-sensor) --- *Product available on Desertcart Oman* *Store origin: OM* *Last updated: 2026-08-26*
