7 Travel Audio Accessories You Didn't Know You Needed

Everyone packs headphones for travel. But there's a category of small, inexpensive audio accessories that solve specific travel annoyances — the kind of problems you didn't realize were solvable until you find the product. Here are seven worth throwing in your carry-on.

1. Airline Headphone Adapter ($5)

Most international flights (and some domestic first-class cabins) still use the dual-prong headphone jack that doesn't fit standard 3.5mm headphones. Without an adapter, you're stuck using the terrible airline-provided earbuds for the in-flight entertainment system.

A dual-prong airline adapter costs $5 and weighs nothing. It lets you use your own headphones — including noise-canceling ones — with the seatback screen. Combine this with your ANC headphones and a long flight becomes dramatically more comfortable. Keep one permanently in your travel bag.

2. Bluetooth Transmitter for Gym TVs and Seatback Screens

Hotel gym TVs, seatback screens on planes, and airport gate displays all have 3.5mm headphone jacks but no Bluetooth. A portable Bluetooth transmitter plugs into the jack and streams audio to your wireless earbuds.

The TaoTronics BT5.0 transmitter ($20) is smaller than a thumb drive, charges via USB-C, and pairs with any Bluetooth headphones. It runs for 15+ hours on a single charge. This is one of those accessories that makes you wonder how you traveled without it.

3. Headphone Splitter With Volume Control ($8)

Sharing audio with a travel partner — watching the same movie on a tablet, listening to the same playlist — requires a headphone splitter. But a basic Y-splitter drops the volume for both pairs and offers no independent control.

A splitter with individual volume controls ($8) lets each person set their own level. This matters more than you'd think when one person prefers background-level audio and the other wants immersive volume.

4. Foam Ear Tips (Replacement Set, $8)

If you use silicone-tipped earbuds, swap to foam tips for flights. Foam tips create a much better passive seal, which reduces ambient noise by 15-20 dB before active noise cancellation even kicks in. The improved seal also dramatically improves bass response.

Comply foam tips are the most popular brand and fit most earbuds. A 3-pair pack costs $8 and makes your existing earbuds significantly more effective in noisy environments.

5. USB-C to 3.5mm DAC ($10)

Modern phones without headphone jacks need a dongle for wired headphones. But not all dongles are equal. A cheap $3 USB-C adapter often has a noisy DAC that introduces audible hiss. The Apple USB-C to 3.5mm adapter ($9) has a surprisingly good DAC that delivers clean, hiss-free audio on both iPhones and Android phones.

This is also your backup audio solution when your wireless earbuds die mid-flight. Pack a cheap pair of wired earbuds ($5) alongside this adapter and you're never without audio.

6. Waterproof Bluetooth Speaker for Hotel Showers ($25)

A small waterproof Bluetooth speaker turns a hotel bathroom into a private concert venue. The JBL Go 4 ($50) is compact enough to fit in a toiletry bag and survives full water submersion with IP67 protection. For even less, budget shower speakers start at $15 and do the job adequately.

This sounds like a luxury, but anyone who's traveled for a week-long conference knows that 20 minutes of your own music in the shower is a meaningful morale boost.

7. Earbud Drying Capsule ($10)

If you run, hike, or exercise while traveling, your earbuds accumulate moisture from sweat. A drying capsule is a small container with silica gel beads that absorbs moisture when you store your earbuds inside overnight. This prevents the driver mesh from corroding, extends earbud lifespan, and eliminates the funky smell that sweaty earbuds develop.

You can DIY this with a pill container and a silica gel packet from a shoe box, but dedicated drying capsules have the right size and better airflow.
