Short answer: the Sony ULT Field 1. It ranks #99 of 179 medium speakers by sound quality, rated 3.1/5, at $138. The Skullcandy Terrain XL ranks #168, rated 2.1/5, at $79.99, $58.01 cheaper, a saving that is not big enough to make up the sound-quality gap.
The Sony ULT Field 1 is the better-sounding choice. A tough, waterproof small speaker that survives drops, with long real world battery life and stereo pairing. It supports AAC Bluetooth, which the Skullcandy Terrain XL lacks. It has an adjustable EQ, which the Skullcandy Terrain XL lacks. Watch for: Upper midrange peak, rolled off treble.
The Skullcandy Terrain XL is the longer-running pick. A very loud, long running Terrain speaker, waterproof with a wrist wrap and a built in microphone. It is rated for 18 hours of battery against 12 for the Sony ULT Field 1. Watch for: Shares the Terrain line’s tuning: no bass, very rolled off treble, and distortion in the treble.
Buy the Sony ULT Field 1. It is rated higher for sound quality, and saving $58.01 with the Skullcandy Terrain XL does not make up for the sound-quality gap.
