For retail buyers, brand procurement managers, or small distributors sourcing Bluetooth speakers, the casing material is often an afterthought—until customers start complaining. A plastic speaker sold to premium European shoppers feels “cheap”; a metal speaker marketed to Latin American outdoor users is too heavy to carry; a fabric speaker for families gets stained and ruined after one spill. The wrong material doesn’t just hurt sales—it leads to returns, negative reviews, and lost trust.
Over 13 years in audio, we’ve tested every casing material on the market, from recycled plastic to aluminum alloy to woven fabric. We’ve learned that material choice directly ties to your audience’s values: durability for outdoor users, aesthetics for premium buyers, affordability for budget shoppers. Let’s break down the three most common Bluetooth speaker casing materials—their pros, cons, ideal use cases, and how to pick the right one for your customers.
First: Plastic Casing—The Budget-Friendly Workhorse
Plastic is the most common speaker casing material, and for good reason: it’s cheap, lightweight, and easy to customize. But not all plastic is created equal—recycled ABS plastic (the kind we use) performs very differently from thin, low-grade polypropylene.
| Pros of Plastic Casing | Cons of Plastic Casing | Ideal Audience & Use Case | Cost (Per Speaker) |
|---|---|---|---|
| Lightweight (200–300g for mini speakers) | Can feel “cheap” if low-grade | Budget shoppers (Latin America, US value retailers), kids’ speakers, promotional giveaways | $1.50–$3.00 |
| Customizable (easy to dye, print logos, or add textures like matte/glossy) | Prone to scratches if uncoated | Brands needing custom colors/logos (e.g., a soda brand’s promotional speaker) | — |
| Impact-resistant (ABS plastic withstands 3ft drops) | Not as premium-looking as metal/fabric | Outdoor users on a budget (hikers, campers who don’t want to risk expensive gear) | — |
| Recyclable (using PCR plastic meets EU sustainability standards) | Can retain heat in direct sunlight | Eco-conscious budget buyers (Europe, Australia) | +$0.50 for PCR plastic |
Our Expert Tip: Avoid low-grade polypropylene—use ABS plastic with a scratch-resistant coating. We had a Mexican retailer switch from polypropylene to our recycled ABS plastic; their “cheap feeling” complaints dropped by 60%, and sales increased by 25%.
For example, a US dollar-store chain used our recycled ABS plastic mini speakers (custom-dyed bright colors) as impulse buys near checkout. They sold 10,000 units in 3 months, with 90% of reviews praising the “sturdy feel for the price.”
Second: Metal Casing—The Premium, Durable Choice
Metal (usually aluminum alloy or stainless steel) is the go-to for premium Bluetooth speakers. It feels high-end, resists scratches, and dissipates heat well—but it’s heavier and more expensive than plastic.
| Pros of Metal Casing | Cons of Metal Casing | Ideal Audience & Use Case | Cost (Per Speaker) |
|---|---|---|---|
| Premium look/feel (sleek, matte, or brushed finishes) | Heavy (400–600g for mini speakers) | Premium buyers (Europe, Japan, US luxury retailers), home audio enthusiasts | $5.00–$8.00 |
| Scratch-resistant (aluminum alloy won’t show wear for 2+ years) | Conducts cold/heat (too hot in direct sun, too cold in winter) | Indoor users (home offices, living rooms) who prioritize aesthetics | — |
| Excellent heat dissipation (prevents overheating during long use) | More expensive to customize (laser engraving only) | Brands with high price points (e.g., $80–$150 speakers) | +$1.00 for laser engraving |
| Resists stains/damage (easy to wipe clean) | Dents if dropped from high heights | Business users (executive gifts, office speakers) | — |
Our Expert Tip: Use aluminum alloy (not stainless steel)—it’s 30% lighter while still being durable. A German premium brand used our brushed aluminum speakers for their “home luxury” line; the speakers sold out in 6 weeks, with reviews calling the casing “elegant and long-lasting.”
One caution: Metal isn’t ideal for outdoor speakers. A Canadian retailer once tried to sell metal speakers for camping—customers complained about the weight (hard to carry) and heat retention (too hot to touch in summer). Switching to plastic cut returns by 45%.
Third: Fabric Casing—The Comfortable, Stylish Option
Fabric (usually woven polyester or recycled cotton) is a middle ground between plastic and metal: it feels soft, looks cozy, and hides minor scratches—but it’s less durable than plastic/metal and harder to clean.
| Pros of Fabric Casing | Cons of Fabric Casing | Ideal Audience & Use Case | Cost (Per Speaker) |
|---|---|---|---|
| Soft, inviting feel (great for home decor integration) | Stains easily (coffee, juice spills) | Home users (living rooms, bedrooms), gift shoppers | $3.00–$5.00 |
| Acoustically transparent (doesn’t muffle sound like thick plastic) | Not waterproof (needs extra coating for outdoor use) | Audiophiles who prioritize sound quality over durability | — |
| Customizable (print patterns, logos, or solid colors) | Fades in direct sunlight | Brands targeting renters (non-permanent decor) | +$0.75 for water-resistant coating |
| Lightweight (250–350g for mini speakers) | Tears if snagged (e.g., by pet claws) | Urban commuters (soft to carry in bags) | — |
Our Expert Tip: Add a water-resistant coating (like our Teflon-treated fabric) for family-friendly or casual outdoor use. A UK home goods retailer used our water-resistant fabric speakers for their “living room” line—customers loved that they could wipe up spills, and return rates for stains dropped by 70%.
A Spanish gift brand used our printed fabric speakers (with floral patterns) for Mother’s Day—they sold 5,000 units, with reviewers saying “it matches my couch perfectly.”
How to Test Casing Durability (Don’t Just Trust the Supplier)
Some suppliers cut corners on materials—they’ll use thin plastic that cracks easily or low-grade fabric that fades in weeks. To avoid this, test the casing with our 4-step method:
- Scratch Test: Rub the casing with a key (light pressure) for 10 seconds. Plastic/metal should show no scratches; fabric should not snag.
- Drop Test: Drop the speaker from 3ft onto a hardwood floor (simulates a home drop). Plastic/metal should not crack; fabric should not tear.
- Heat Test: Leave the speaker in direct sunlight for 2 hours (simulates outdoor use). Plastic should not warp; metal should not get too hot to touch (under 45°C); fabric should not fade.
- Stain Test (for fabric): Spill 10ml of coffee on the fabric, wait 5 minutes, then wipe with a damp cloth. Water-resistant fabric should wipe clean; non-resistant should leave minimal residue.
We once rejected a batch of fabric speakers because the material faded after 1 hour of sunlight—saving our client (a US home retailer) from $7,000 in returns.
