Soundcore Boom 2 Plus: problems, parts and running costs

Checked: 2026-10-19

Summary

A large, waterproof and floatable Bluetooth party speaker (model A3134) with 140W max output, a 20-hour battery and app EQ. The recurring complaints are a boomy, hollow out-of-box tuning, poor directivity, thin mid and treble detail, and distortion above 50-60% volume reported by one owner. There are no parts, consumables or subscriptions, so the running cost is $0. It is strong value under $150, fair at $151-$200, and weak above $200 unless you specifically need the Soundcore ecosystem.

Common problems and fixes

Boomy, hollow out-of-box sound — multiple owners describe the default tuning as boomy and hollow; the fix is EQ adjustment through the soundcore app’s 9-band Pro EQ. [11]
Distortion at high volume — one owner reports distortion and overmatched bass above 50-60% volume; the workaround is to stay below that range or turn BassUp off. [10][2]
Poor directivity — RTINGS finds the sound two-dimensional, with instruments and voices losing placement; Consumer Reports describes a grainy, congested, sibilant midrange and smeared, sizzly treble. No fix; it is a design limitation. [5][7]
Auracast only on newer hardware — Auracast works only on units from the November 2025 hardware update onward; earlier units support PartyCast 2.0 only, so check the revision before buying for Auracast. [2]
Confusing microphone spec — B&H lists a built-in mic for hands-free calls, but RTINGS lists “Speakerphone: No” and Consumer Reports says there is no speakerphone functionality or built-in microphone; treat the mic as unconfirmed. [15][5][7]
Heavy for a portable — 8.38 lb (3.8 kg); fine for short carries and tiring on trails. [2]

Parts and consumables

No replaceable parts or consumables reported. No user-repairable parts catalog was found for this model and the battery is non-user-replaceable; the eventual battery service cost is unquantified. In the box: speaker, USB-C to USB-C cable (23.6 in), detachable shoulder strap and quick-start guide. [18][3][5]

Yearly running cost

Nothing recurring: no subscription is required, there are no replaceable parts or consumables, and no replacement schedule exists. The typical owner spends $0 per year beyond the purchase price; the only possible future cost is a non-user-replaceable battery service, for which no price was found. [18]

When it is a good buy

The Boom 2 Plus launched at $249.99 in May 2024, Consumer Reports listed it from $179.99 in July 2025, CNET put it around $220 in October 2024, and Reddit owners report paying $100-$155 on sale [1][6][7][14][9][11]. At $150 or less it is strong value for a loud waterproof party speaker with full stereo and a 20-hour battery; $151-$200 is fair; above $200 it only makes sense if you specifically want PartyCast 2.0 multi-speaker linking or the app ecosystem [9][11]. Named alternatives: the JBL Xtreme 4, which RTINGS recommends over the Boom 2 Plus for outdoor use on better directivity, IP67 sealing and a 27-hour battery [5]; the smaller Soundcore Boom 2 (80W, model A3138), the better choice when CNET’s verdict that the Plus costs around $220 and does not sound twice as good matters more than raw output [14][6].
