Campfire Audio Astrolith earbuds don't just look good, they're built that way on purpose

I'm a massive advocate for investing in a really good pair of wireless earbuds. Whether you're an audiophile, a podcast connoisseur, or just spend most of your day on video calls, a good pair can really enhance your life.

I've been lucky to test a whole range as part of my work here. That includes everything from budget options like the OnePlus Buds 3, right through to bank-busting pairs like the Devialet Gemini II.

This latest offering from Campfire Audio blows them all out of the water, though. Nursing a cool £2,199 ($2,199; approx. AU$4,300) price tag, these IEMs represent pretty much the most premium audio experience you can buy.

Still, at least there is a pretty impressive spec sheet to match. Inside, these buds pack a monumental 14.2mm driver. Those cater to sub, low and mid frequencies, while a 6mm tweeter adds in high-end frequencies. Those are specifically tuned to offer definition with even the faintest details within your music.

Of course, the design of these buds is a big part of the overall package. You'll spot the hand-polished, mirror-finish stainless steel shells from a mile off, with a sumptuous stepped design which simultaneously looks space age and Art Deco.

That's not just a pretty face, though. The housing is part of the brand's Additive Acoustic Optical Inclusion (AAOI) housing technology, which uses a precise system of internal acoustic chambers to ensure some of the best sound quality currently available.

That includes a frequency response from 5Hz all the way to 25kHz, with a total harmonic distortion of less than 0.3%. That is complemented by a diaphragm design which ensures that the voice coil won't warp or bend at high volumes.

All in all, these look like a serious piece of kit for the truest of audiophiles. They're certainly a pretty penny, but that will be more than worthwhile to those who demand the absolute pinnacle of audio performance from an in-ear device.
