Altec Lansing LifeJacket H2O 4 Waterproof Bluetooth Speaker

The Altec Lansing LifeJacket H2O 4 is a rugged, fully sealed Bluetooth speaker that delivers portable stereo sound with up to 10 hours of playtime and a 100-foot wireless range.

Built for people who take their music outdoors, the LifeJacket H2O 4 combines an IP67-rated enclosure with long battery life and reliable wireless connectivity. Its compact cylinder design balances durability and portability so you can use it at the pool, on a hike, in a kayak or around the house without worrying about water, dust, or bumps.

How far can I place the speaker from my phone or tablet?

The LifeJacket H2O 4 uses Bluetooth 4.2 and an optimized antenna design for extended range, allowing playback from up to about 100 feet in open areas. Walls, crowds, and interference will reduce that distance, but typical indoor use still provides a comfortable wireless reach.

• Bluetooth 4.2 for stable connections
• Designed antenna for greater real-world range
• Best performance in line-of-sight or open outdoor settings

What level of water and impact protection does it offer?

This model carries an IP67 rating, meaning it’s fully dustproof and can be submerged in freshwater to one meter for short periods. The rugged exterior also absorbs shocks and resists snow and sand, so the speaker stands up to active outdoor use.

• IP67: dust-tight and temporary water immersion safe
• Shock-resistant housing to handle drops and bumps
• Works reliably at the beach, poolside, campsite, and on the trail

How long will the battery last and how does it sound?

On a single charge the LifeJacket H2O 4 delivers up to 10 hours of playback, enough for a day trip or evening gathering. It produces clear stereo audio with punchy bass from high-sensitivity drivers, tuned to keep vocals and beats audible at common listening levels.

• Up to 10 hours of continuous playback per charge
• Stereo drivers with focused midrange and boosted low end
• Minimal distortion at reasonable volume for outdoor listening

Can I use voice assistants and take calls with it?

Yes — the LifeJacket H2O 4 supports voice assistant access and functions as a speakerphone. Pair it with a smartphone to summon Siri or Google Assistant, make hands-free calls, or control music without touching your device.

• Works with Siri and Google Assistant via Bluetooth
• Built-in microphone for hands-free calling
• Compatible with most Bluetooth-enabled phones, tablets, and laptops
