Anker Soundcore Boom 2 SE Black

Soundcore Boom 2 SE Portable Bluetooth Speaker — Black (Model A3148)

The Soundcore Boom 2 SE is a compact entry into the Boom 2 family — a 30W IPX7-rated outdoor speaker that floats, charges other devices via a built-in USB-A power bank, and connects to over 100 Soundcore speakers simultaneously through PartyCast 2.0. Where the Boom 2 Plus targets large outdoor gatherings at 140W, and the Boom 3i prioritises rugged adventure use at 50W with IP68 protection, the Boom 2 SE focuses on everyday portability — offering 18 hours of battery life, a carry handle, and PartyCast 2.0 multi-speaker capability in a smaller, lighter chassis with a lower entry price.

Use Cases

Everyday Outdoor Listening

The Boom 2 SE suits casual outdoor use — garden sessions, beach outings, park picnics, and pool afternoons — where IPX7 waterproofing and floating capability provide meaningful protection without the weight or price premium of higher-output options. At 30W the Boom 2 SE covers intimate to mid-sized outdoor spaces comfortably. Buyers expecting coverage across a large open garden or beach area may find the Boom 3i’s 50W or the Boom 2 Plus’s 140W more appropriate.

Multi-Speaker Party Setups

PartyCast 2.0 scales the Boom 2 SE’s audio across over 100 compatible Soundcore speakers simultaneously — useful for buyers who already own other PartyCast 2.0-compatible speakers such as the Boom 2 Plus or Boom 3i and want to extend their setup cost-effectively. Two Boom 2 SE units in TWS mode additionally provide left/right stereo separation for a more immersive listening experience than a single unit delivers.

Travel and Day Trips

The carry handle and IPX7 rating make the Boom 2 SE practical for holidays, camping trips, and day outings where the speaker travels in a bag alongside wet swimwear or outdoor gear. The 18-hour battery covers multiple days of moderate listening between charges, and the built-in 5W USB-A power bank keeps phones functional during outdoor activities where wall sockets are unavailable.

Calls and Background Music at Home

The built-in microphone supports hands-free calling through the speaker — pausing music, taking a call, and resuming playback without needing the phone. The soundcore app’s EQ presets adapt the sound profile to different room environments or music genres. The auto-off function prevents battery drain during unintentional extended pauses.

Considerations

Audio, Codec and Connectivity

30W output suits personal and small-group listening. The Boom 2 SE delivers adequate volume for intimate outdoor settings and smaller gardens. For events, beaches, or outdoor areas where a speaker needs to compete with ambient noise across a large space, the 50W Boom 3i or 140W Boom 2 Plus provides more headroom. PartyCast 2.0 linking multiple Boom 2 SE units addresses coverage gaps cost-effectively.

SBC Bluetooth codec only. The Boom 2 SE does not support AAC. For Apple device users — iPhone, iPad, Mac — SBC applies across all Bluetooth connections rather than the higher-quality AAC available on other Soundcore speakers such as the Boom 2 Plus and Boom 3i. For outdoor casual listening, the practical difference is minimal; for critical listening, it matters.

No AUX input. The Boom 2 SE does not include a 3.5 mm AUX port. Buyers who need wired audio input — from a mixer, turntable, TV, or non-Bluetooth source — should consider the Boom 2 Plus, which includes AUX-in.

Battery and Charging

Port cover must seal fully before water exposure. IPX7 protection depends entirely on the USB-C and USB-A port covers sitting flush and locked. An unsecured cover compromises the waterproof seal. After water exposure, dry the ports and covers thoroughly before charging.

Power bank output is 5W — slower than modern fast charging. The USB-A power bank charges phones at 5W, which tops up modern phones slowly compared to the 10W USB-C output on the Boom 2 Plus. For topping up a low battery in an emergency it works well; for fast charging it does not.

Frequently Asked Questions

How long does the Soundcore Boom 2 SE battery last?

Up to 18 hours at 50% volume with BassUp off, tested in Soundcore’s laboratory. Higher volumes and BassUp active will reduce this figure. For all-day outdoor use, moderate volume with BassUp off maximises runtime.

Does the Soundcore Boom 2 SE float?

Yes. The IPX7-rated chassis floats when placed on water. The port cover must seal fully before any water contact to maintain the IPX7 waterproof protection.

Can the Boom 2 SE charge my phone?

Yes. The USB-A port on the rear outputs 5W for charging phones and small accessories. This power bank function operates while the speaker powers on. Note the 5W output charges slowly by modern standards — suitable for emergency top-ups rather than fast charging.

Does the Boom 2 SE have an AUX input?

No. The Boom 2 SE does not include a 3.5 mm AUX input. For wired audio connectivity, the Boom 2 Plus includes an AUX-in port.

What Bluetooth codecs does the Boom 2 SE support?

SBC only. The Boom 2 SE does not support AAC, aptX, or LDAC. All Bluetooth connections use SBC regardless of the connected device. For AAC support — relevant to Apple device users — the Boom 2 Plus and Boom 3i both support AAC.

How do I pair multiple Boom 2 SE speakers together?

Turn on all Boom 2 SE speakers. Press the PartyCast button on each speaker; the indicator light turns white on each. A confirmation sound indicates successful PartyCast 2.0 pairing. For TWS stereo with two units, long press the Bluetooth button on both speakers simultaneously until the indicator flashes white, then listen for the confirmation tone.
