ASUS Adol SP103: A $35 Bluetooth 6.0 Speaker You Can't Buy Outside China
ASUS has launched a new budget Bluetooth speaker in China under its Adol sub-brand, and the specs-per-dollar ratio is hard to ignore. The SP103 goes on sale via JD.com at 239 yuan — roughly $35 — with Bluetooth 6.0, a 10W dual-driver setup, and onboard microSD playback. There's just one catch: it isn't available anywhere outside China right now, with no confirmed US or UK retail presence.
The hardware
The SP103 is a flat, puck-style speaker measuring 180×180×49mm and weighing 575g — closer to a JBL Clip in footprint than a cylindrical Soundcore. The front is wrapped in dense fabric; the back is matte metal with a ribbed non-slip pad built in. Physical buttons handle power, pairing, volume, and track control. Three pastel colorways are offered: Iris Purple, Rose Gold Pink, and Sage Green.

Audio comes from two full-range drivers with a racetrack-style diaphragm, covering 50Hz–20kHz at a combined 10W. That's a reasonable spec on paper for a speaker this cheap, though without independent testing it's impossible to judge real-world sound quality.
The SP103's dual full-range drivers and racetrack diaphragm aim for broad frequency coverage at a budget price.
Connectivity goes beyond the basics. Bluetooth 6.0 — still rare in sub-$50 speakers, where BT 5.0–5.3 remains the norm per Gizmochina — offers a claimed 10-meter range. TWS pairing lets two SP103 units link into a stereo pair. There's also a 3.5mm AUX input for wired sources like laptops or projectors, and a microSD slot for offline playback without a phone. USB-C handles charging.

The 2,600mAh battery is rated at 10 hours at 70% volume, dropping to around 4 hours at maximum. That's a fair but not exceptional figure — the Anker Soundcore 2 claims 24 hours.
Not coming to a store near you
Right now the SP103 is a China-only product. ASUS does not list the Adol line on its global website, and no US or UK retailer carries it. The established competition — JBL Go 5 at $49.95 and Anker Soundcore 2 at around $30 — are both widely available with local warranties and customer support, which matters when something goes wrong.
Grey-market imports via resellers on Amazon or eBay are possible, but unofficial. Without an ASUS distribution deal, US and UK buyers have no recourse if the unit arrives with issues. Bluetooth 6.0 is a genuinely forward-looking feature, but its real-world advantage over BT 5.3 at this range and price point is unlikely to be noticeable day-to-day.
The SP103 is an interesting product at an aggressive price. Whether ASUS's Adol brand ever pushes it into Western markets is another question entirely.
