Anker Soundcore Select4 Go Portable Speaker

Anker Soundcore Select 4 Go Green — Pocket-Sized Waterproof Bluetooth Speaker

The Anker Soundcore Select 4 Go Green is a mini Bluetooth speaker engineered for places ordinary speakers cannot survive. Rated IP67 against dust and water, it can be immersed up to 1 m (3.3 ft) deep for 30 minutes and even floats, making it a natural fit for the shower, the pool, the lake, or a beach picnic. The included lanyard strap and built-in loop let it clip to a backpack, belt loop, or shower hook, so music travels wherever the day goes. Despite the compact footprint, the speaker pushes 5W of output through a 45 mm dynamic driver, producing the punchy, full-bodied sound Soundcore is known for in this category.

Up to 20 hours of playback on a single charge means the Select 4 Go can soundtrack a full day at the beach, a long hike, or an evening of poolside lounging without reaching for the cable. Bluetooth 5.4 with a 30 m wireless range keeps the connection stable across rooms, and the Soundcore companion app unlocks a customizable 9-band EQ for fine-tuning the sound profile. The Anker Soundcore Select 4 Go Green is the right choice for active listeners and outdoor enthusiasts who need a rugged, go-anywhere speaker that survives splashes, dunks, and dust without sacrificing sound.

Built for Water, Dust, and the Outdoors

What separates the Select 4 Go from a typical mini Bluetooth speaker is its combination of an IP67 enclosure, a floating body, and a PC+ABS shell designed to shrug off harsh outdoor conditions. The USB-C charging port sits behind a sealed cover, and the rubberized base grommets keep the unit planted on slippery shower tiles or pool decks.

• Water & Dust Protection: IP67 rated — sealed against dust and submersible up to 1 m / 3.3 ft for 30 minutes
• Floating Design: Buoyant body — drops into the pool or lake and stays on the surface while playing
• Enclosure Material: PC+ABS — a tough, lightweight composite that resists everyday knocks and scratches
• Built-In Strap: Included lanyard — clips to a backpack, belt loop, or shower hook for hands-free carrying

Sound Performance & Battery Life

Sound quality and stamina are the two specs that decide whether a portable speaker is worth packing, and the Select 4 Go is tuned to deliver both at this size and price tier. The 5W amplifier feeds a single 45 mm dynamic driver in a mono configuration, with a 3 ohm impedance and a 85 dB signal-to-noise ratio for clean playback.

• Output Power: 5 W — punchy volume that easily overpowers shower noise
• Driver Size: 45 mm dynamic driver — the same size class used in much larger portable speakers
• Battery Life: Up to 20 hours per charge — covers a full day of mixed indoor and outdoor listening
• Battery Capacity: 2.4 Ah — recharges via the included 30 cm USB-A to USB-C cable in around 4.5 hours

Wireless Connectivity & Stereo Pairing

Wireless range, latency, and pairing flexibility matter when a speaker is used across rooms, outdoors, or in stereo with a second unit. The Select 4 Go uses Bluetooth 5.4 with a 30 m line-of-sight range and supports True Wireless Stereo (TWS) pairing so two speakers can be linked for a wider, more immersive soundstage.

• Bluetooth Version: 5.4 — stable wireless streaming with broad smartphone and tablet compatibility
• Wireless Range: 30 m / 100 ft — leaves the phone on the towel while the speaker plays by the pool
• TWS Pairing: True Wireless Stereo — connect two Select 4 Go units for left/right stereo separation
• App Control: Soundcore companion app — 9-band EQ customization and firmware updates over the air

Who the Anker Soundcore Select 4 Go Green Is For

The Anker Soundcore Select 4 Go Green is the right choice for shower listeners, pool owners, beach-goers, campers, and bikers who need a rugged, ultra-portable Bluetooth speaker that can survive splashes, rain, and even full submersion. Its 20-hour battery and pocketable form factor make it equally at home on a hotel desk, a golf cart, or a kayak. The TWS pairing option also makes it a smart pick for anyone who wants to start with one speaker and add a second later for a true stereo setup. The Anker Soundcore Select 4 Go Green suits entry-level buyers and casual listeners who want reliable, no-fuss sound in a package that costs less than a night out.
