Almost the entire cost of a silent disco is headphones. Once you see the quote broken down per component, the question stops being "how much does this cost?" and becomes "do I actually need to hand out hardware?"
The default path. A rental company supplies receiver headphones and one or more transmitters, usually with delivery and pickup.
| Line item | Typical range | What drives it |
|---|---|---|
| Headset, per unit per night | ~$5–15 | Volume discounts at higher counts; multi-day rates are cheaper per night |
| Transmitter(s) | Often included | One per channel; three-channel setups need three |
| Delivery + pickup | ~$50–150 | Distance, timing, whether you can collect yourself |
| Refundable deposit | Varies, can be large | Held against loss and damage across the whole set |
| Damage waiver (optional) | ~5–15% of rental | Caps your liability for the inevitable casualties |
| On-site staff (optional) | Hourly | Handout, collection, troubleshooting |
For a 50-person party, the headsets alone plausibly reach several hundred dollars before delivery. That's the number that stops most house parties, and it scales linearly — doubling your guest list doubles your bill.
Makes sense only if you're running events repeatedly — a mobile DJ, a fitness studio, a venue, a tour.
| Line item | Typical range | Notes |
|---|---|---|
| Receiver headsets | ~$40–120 each | Cheap units exist; battery life and build quality are where the money goes |
| Transmitter | ~$200–800 | Range and channel count drive price |
| Cases / charging carts | ~$100–500 | Genuinely necessary at scale — charging 50 units by hand is miserable |
| Ongoing | Batteries, repairs, replacements, storage | The part people forget when doing the maths |
A 50-headset kit is a four-figure investment before you've run a single event. The rough rule: buying beats renting when you're running events monthly rather than occasionally — and even then, only if you're set up to store and charge them.
The third option is to stop supplying receivers at all, because every guest already brought one. Their phone is the receiver; their own earbuds are the headphones.
| Line item | Cost |
|---|---|
| Host software | $0 — free Mac app |
| Receivers (guest phones) | $0 — they already own them |
| Headphones (guest earbuds) | $0 — they already own them |
| Guest app install | $0 — not required, it's a web link |
| Delivery, deposit, damage waiver | $0 — there's nothing to deliver or lose |
| Spare earbuds for forgetful guests | ~$15–30 for a handful of cheap pairs |
That last line is your entire equipment budget. Everything else — the sync, the streaming, the QR code, unlimited guests — costs nothing, and critically, it does not scale with headcount. A 200-person party costs the host exactly what a 20-person party costs.
There's a party running right now. Open it on your phone with earbuds — that's the guest experience, end to end. Open it on two phones to hear the sync yourself.

Renting, you're typically looking at several hundred dollars once headsets, delivery and a deposit are included. Using guests' own phones, the cost is the price of a few spare earbuds — the software and the streaming are free, and it doesn't get more expensive as the guest list grows.
Budget receivers usually cost you in battery life, comfort, and build quality — which matters most in exactly the situation where you own them and are using them repeatedly. If you're only running the occasional event, this is an argument for not owning hardware at all.
Only for radio-based systems. Phone-based silent discos have no transmitter — the audio travels over the internet to each guest's browser, which is why there's no hardware cost and no range limit within the venue.
Usually, minus anything lost or damaged. This is worth asking about explicitly, because "we counted 48 of 50 back" is a common and expensive end to an otherwise good night.
The honest limits: guests need earbuds and a working data or Wi-Fi connection, it's a single channel rather than the three-channel switching format, and you don't get the glowing-headphones visual. If none of those matter for your event, there's no catch.
Free Mac app, unlimited guests, nothing for anyone to install. Set up in about five minutes.
