Price: $20 (MSRP $30)
Key features: Waterproof
Wear style: Over the ear or straight down

In Short: Cheap waterproof earbuds with a neutral sound signature.

Quick overview:

As I mention in the other H2O Audio reviews, these headphones are completely waterproof and there aren’t many headphones on the market that can make that claim. Fortunately, you won’t be sacrificing much in the way of sound quality in order to get your hands on that feature.

In many ways the Flex is the little brother of the Surge Pro Mini, offering up a neutral sound signature.

While the bass is lacking in power compared to the Surge and most other budget headphones, the Flex has several qualities (besides being waterproof) that make it a solid choice. The presentation is smooth, laid-back, and non-fatiguing which makes it difficult to dislike. Second, the soundstage is phenomenal and is the highlight of the headphone – it is very wide and the imaging is impressive. The Flex puts a slight emphasis on the mid-range but as I mentioned it remains neutral overall.

For a headphone whose primary feature is complete water resistance, the Flex delivers much better sound quality than I expected. For a spacious, enveloping sound at a low price, the Flex is the way to go.
