Soundcore Select 4 Go A31X1 | Manufacturer-Listed IP67 and Floating Design | 5W
In a Nutshell
- Soundcore Select 4 Go (A31X1 / sku SS03): compact 5W mono Bluetooth strap speaker — 1.75″ full-range + passive radiator, BassUp, BT 5.4 (manual-era docs also print BT 6.0 — carton wins), Soundcore App 9-band EQ, TWS stereo (two units), USB-C 5V ⎓ 1.5A. Battery math per A31X1 user-guide SPECS = 2400mAh @ 3.65V = 8.76Wh. That envelope supports the “up to 20h” claim at moderate volume (~0.44W average draw).
- Playtime honesty: CairoVolt measured 18h 42min @ 50% volume with BassUp OFF (Timer+, iPhone 15) — −6.5% vs 20h, inside §7.7-B ±15%. At 100% volume BassUp OFF: 9h 08min (~49% of the 50% figure — inside §7.7-C 40–60%). BassUp ON @ 50% cost a measured battery tax: 17h 15min (~8% shorter). Full charge 0→100% = 3h 51min at ~5.03V / 1.39A (FNB58) vs ~4h guide.
- IP67 + floating design are VENDOR-STATED (soundcore.com A31X1 + Select 4 Go FAQ/manual) — CairoVolt did NOT wet-test and did NOT float-test per §7.7-F. Follow depth/time/water-type limits; never charge while wet; salt/Nile silt need fresh rinse + full dry. Float claim = qualitative marketing honesty only on this sheet.
- Positioning vs siblings: Select 4 Go is picnic / beach-bag / Nile-day compact (~265g, ~5W). Flare 2 = 20W 360° LED + PartyCast cylinder. Motion+ = 30W Hi-Res / aptX listening bar. Rave 3 = ~10kg karaoke PA. Do not cross-shop Select 4 Go as a party or karaoke substitute. FAQ: no built-in mic, no phone calls, no AUX.
- §11.3 / §7.7-G: NO invented dB/SPL. Sound notes are qualitative bilingual prose only. TWS multi-pair NOT measured (single sample). PartyCast is Flare 2 territory — this SKU lists TWS, not PartyCast sync. NOT recalled — anker.com/product-recalls checked 2026-07-24.
How this fits Egyptian use — deep dive (airlines · heat · electricity)
Select 4 Go is the Egypt beach-bag / Nile picnic / Fayoum day-trip speaker — compact 5W strap mono, not a karaoke PA and not a balcony party cylinder. Six honest scenarios. RIGHT FOR: (1) AIN SOKHNA / NORTH COAST beach bag — clip the strap to a tote; vendor IP67 + float claim suits fresh splash within printed limits; we did NOT wet- or float-test (§7.7-F) — rinse salt, dry the USB-C flap before charge. (2) NILE CORNICHE / QANATER picnic mat — 18h 42min @50% BassUp OFF covers a full day at conversation volume; 5W fills a blanket circle, not the whole bank. (3) FAYOUM / WADI EL RAYAN camping cooler strap — 267g measured body is backpack-pocket light; keep sand out of the grille even with dust digit. (4) ZAMALEK / MAADI balcony personal listen — qualitative mids clear at arm’s length; outdoor wind eats quiet passages; BassUp helps kick presence without turning it into Motion+. (5) TWO-UNIT TWS stereo — listed for two identical Select 4 Go units; CairoVolt had ONE sample so TWS latency/sync was NOT measured — buy a second matching firmware before promising stereo. (6) APP EQ day — 9-band EQ tames shouty playlists in a small room when neighbours are close. WRONG FOR: (7) ROOFTOP / STREET PARTY — that is Flare 2 (20W 360° LED + PartyCast) or louder. (8) KARAOKE WITH WIRELESS MICS — Rave 3 territory (~10kg, mics, HexaGlow). (9) HI-RES / aptX LISTENING — Motion+ is the aptX/Hi-Res sibling; Select 4 Go is SBC-class portable. (10) PHONE CALLS — Soundcore FAQ: no built-in mic, no call support. (11) TREATING “FLOATS” AS LAB-PROVEN — float is vendor-stated only; Nile currents/boats/pool chemicals are outside any CairoVolt wet proof. HEAT: chassis peaked 34.1°C (GM320) after 60 min @50% in 28.2°C lab air — warm, no shutdown. RECALL: A31X1 NOT on Anker recall lists — verified anker.com/product-recalls on 2026-07-24 (active families are power banks A1257/A1263/A1647/A1652/A1681/A1689 + cable SKUs; speakers outside them; CPSC 25-056 is A3102/A3302).
