UPS took this run by a nickel over USPS. Margins that thin are exactly why comparing beats guessing.
What one pair actually quoted
The input was two words, "wireless headphones", plus Newark, NJ 07102 and Atlanta, GA 30303. Everything below, from the box dimensions to the battery screening, came back from that single request on 2026-07-27.
What we typed
wireless headphones
Studio monitors in a hard case and folding earbuds are different parcels; describing yours precisely tightens the estimate.
Packed box it returned

The packed figure was 1.7 lb (0.75 kg).

An eastern-seaboard-to-Southeast lane that every ground network prices aggressively.
| Carrier | Service | Price | Estimated transit |
|---|---|---|---|
| UPS | Ground | $11.07 | 3-4 business days |
| USPS | Ground Advantage | $11.12 | 6-7 business days |
| FedEx | Ground | $21.96 | 3-4 business days |
Anything with a built-in lithium cell rides the ground network through SMKlog checkout, which costs you nothing in practice: the two cheapest services here were ground anyway, and both beat the airfreight-style options that a battery would have ruled out.
Packing pointers for audio sellers
Case in, cans safe
Fold the headphones into their travel case if one exists, then float that case in a box with soft fill. Headband adjusters and hinge points snap when a bare pair rattles loose.
Batteries, the allowed way
A cell sealed inside the headphones keeps checkout self-service. What SMKlog restricts are power banks, spare loose batteries, and gear that is damaged or recalled; leave those out of the box.
Photograph the serials
Snap the serial number and condition before sealing the carton. If a buyer disputes what arrived, a timestamped photo settles it faster than any paragraph you could write.
Headphone shipping FAQ
How much does it cost to ship headphones?
Between $11.07 and $21.96 on our 2026-07-27 Newark to Atlanta run, depending on service. UPS Ground took the low end; FedEx Ground wanted nearly double for the same window.
Are wireless headphones allowed in the mail?
Yes. The built-in battery simply routes them to ground services with a UN3481 lithium mark, which SMKlog checkout handles as part of buying the label.
Should I remove the ear cushions before shipping?
Leave them mounted but slide a strip of paper between cushion and driver grill if they are removable. Compressed foam recovers; a cracked driver housing does not.
Is USPS or UPS cheaper for a small electronics box?
On this run they were nearly tied, $11.12 against $11.07, with UPS also two days faster. That ordering flips route by route, so check both every time.
