Anker Soundcore 2 Bluetooth Speaker: features, specs and who it suits

The Anker Soundcore 2 (model A3105) is a small portable Bluetooth speaker built for listening away from a power outlet. It combines a 12W output, a water-resistant body and a battery that Anker rates for a full day of playback. It is aimed at people who want one speaker for the kitchen shelf, the campsite and the beach bag.

What 12W and dual drivers mean

Anker says the speaker delivers 12W through two neodymium drivers, with a digital signal processor managing the output. Two drivers let the speaker split the work and generally fill a small room or a patch of garden. As with any speaker this size, wattage is a rough guide to loudness rather than quality, and very small enclosures cannot move as much air as a large one.

How BassUp and the bass port work

Anker's BassUp feature boosts low frequencies, and a spiral bass port is used to extend the low end from a small cabinet. In general, a port lets the air inside the enclosure reinforce deeper notes. Boosted bass suits pop, hip-hop and dance music, while those who prefer a flatter sound may find it prominent.

Battery life in real use

The 5,200mAh lithium-ion battery is rated by Anker at up to 24 hours of playtime. Battery-life figures are usually measured at a moderate volume, so loud, bass-heavy listening will typically shorten the time between charges. A day-long figure still means that a weekend trip may need only one charge.

Water protection explained

IPX7 means the speaker is rated to survive immersion in water to a stated depth for a limited time. It covers water only, not dust, because the "X" means dust protection was not specified. Anker describes it as protected against splashes, waves and water vapour. Rinsing off sand and drying the speaker afterwards is sensible, and the ports should be dry before charging.

Stereo pairing and controls

The speaker uses Bluetooth 5 and supports wireless stereo pairing. Pairing two compatible units usually lets one play the left channel and the other the right, which widens the sound. Anker describes the controls as simple, with physical buttons on the body.

Size and where it fits

It measures about 1.8 x 6.5 x 2.1 inches (roughly 4.6 x 16.5 x 5.3 cm) and weighs 0.9 lb (about 410 g). That makes it easy to slip into a backpack side pocket or a bike bag.

Who it suits

It suits people who want a single, portable speaker for travel, camping, garden use or a kitchen counter. Those who want a speaker for large gatherings, or a detailed, full-range sound for critical listening, may look at larger products.

What to check before you buy

• Pairing: wireless stereo pairing needs a second compatible speaker, so confirm which models work together.
• Charging: check what cable and power adapter are in the box and what you need to supply.
• Water use: read the manual on submersion, salt water and drying before taking it near water.
• Sound taste: the boosted bass may be more than you want for spoken word or acoustic music.
• Size: compare the dimensions with the space where you plan to carry it.
