Do bone conduction headphones sound good? An honest answer before you buy

The direct answer

No, not by the standard of a good earbud, and yes, by the standard of what you're buying them for. Nobody chooses bone conduction for fidelity. They choose it because their ears stay open, their headphones can't fall off, and their sweat doesn't matter. The sound is the price of those three things, and the price is: thin bass, a slightly hollow tone, and a tickle when you turn it up. If that's acceptable for a podcast at 6 a.m. on a road shoulder, the category works. If you want to hear a bass line, it doesn't.

What it sounds like, described

Voices are clear and natural; that's the frequency range bone transmits best, and it's why bone-conduction headsets exist for calls. Guitars, keys, cymbals: present and reasonably crisp. Kick drum and bass guitar: a suggestion rather than a thump. The overall impression is a little like a good pair of small speakers heard from the next room, except that it's also perfectly located inside your head. SoundGuys' summary of the best of the category: they “don't sound as good as a pair of the best headphones on the market will.” We haven't heard these; that's their finding and it matches every published review we've read.

Why the bass is missing

Bass is low-frequency motion of a lot of air. A sealed earbud makes it by pressurizing the tiny volume of air in your canal. Bone conduction has no air to move; it vibrates the temporal bone, and low frequencies through bone require enough energy that you'd feel it as a rattle rather than hear it as a note. Makers push the transducers as far as they can, and the result is what SoundGuys describes. The physics is in bone conduction vs air conduction.

What it's good for

• Podcasts and audiobooks. Voice is the sweet spot. Many owners use bone conduction for nothing else.
• Calls. Same reason, plus you hear your own voice naturally with open ears.
• Music you already know at moderate volume outdoors, where the environment fills in what the headphone doesn't and awareness matters more than fidelity.
• Anywhere you need to hear the room: a bike lane, a shared trail, a home with kids.

What makes it sound better

1. DualPitch. Shokz's 10th-generation system (OpenRun Pro 2) adds an air-conduction unit beside each bone transducer to supply the bass bone can't. Shokz calls the Pro 2 its music-focused model, and it's the highest sound score we give a neckband (6 of 10). Older PremiumPitch models (OpenRun, OpenMove) don't have it.
2. Placement. The pads should sit on the cheekbone just in front of the ear, not on the soft tissue of the cheek. A millimeter or two changes the tone. If it sounds tinny, it's probably too low.
3. EQ. The Shokz app on Pro 2 and Air 2 has presets and custom EQ (six plus two on the Pro 2). A modest bass lift helps within the limits above.
4. The earplug trick. Plugging the canal with foam earplugs removes ambient sound and makes bone conduction sound dramatically fuller, because the bone-conducted signal is no longer competing with air. Suunto ships earplugs with the Wing for this reason. It also defeats the point of open ears, so it's a treadmill trick, not a road trick.

The buzz and the tickle

If sound is the priority

An open-ear air-conduction hook keeps the ears open and sounds noticeably fuller. The Shokz OpenFit 2's dual drivers score 8 on our sound metric against the OpenRun Pro 2's 6, with the same IP55 rating and nearly the same battery. You give up the neckband's fit and its no-case simplicity. The decision is in open-ear vs bone conduction; the head-to-head is OpenRun Pro 2 vs OpenFit 2.
