Affordable, great-sounding, durable, waterproof Bluetooth headphones for outdoor use and sports are rare. The SENSO ActiveBuds S-250 is a rare exception. Go for it!!!

How do you recognize poorly designed wireless Bluetooth headphones for sports from a pair that’s up to the task? Online reviews can help you with that. The SENSO ActivBuds S-250 has earned 5 stars from over 16,000 reviews on Amazon, and we can see why. For a very affordable price, they offer quite a lot regarding build quality, sound, accessories, and looks. Could these be the headphones you’ve been looking for all this time? Let’s find out.

Build and Design

The IPX7 waterproof standard ensures that any devices with this prestigious rating are protected against water immersion for 30 minutes at a depth of 1 meter. The ActivBuds S-250 passes this rating with flying colors, being one of only a few wireless sports headphones on the market that you can take with you underwater. The sound quality may suffer a bit, but that’s nothing compared to the fact that you can swim with them.

The headphones are powered by a new, improved battery capable of lasting up to 8 hours on a single charge and 240 hours on standby. The battery features a quick charge functionality, which brings it up to 100% in under 1.5 hours.

Integrated into the earbuds are two ergonomic ear hooks that wrap around your ears and keep the headphones securely attached even if you decide to do yoga up-side-down.

Not much can be said about the design—it’s simple, and it works. Many sports headphones try to attract users with crazy color schemes and alien-like nozzle shaping, and nearly all of them fail miserably. These headphones stick to the proven formula, and we can’t fault them for that.

Sound Quality

Featuring the latest Bluetooth 4.1 CSR technology for excellent wireless reception and high-fidelity sound over long ranges, the SENSO S-250 wireless sports headphones can seamlessly connect with all Bluetooth-enabled devices up to 30 feet away, and their Noise Suppression technology makes outside noise disappear.

When tested with a range of tracks, featuring a few popular hip-hop albums, some jazz, rock, and even the occasional metal track, the high-definition nature of the sound of the ActiveBuds S-250, including their deep bass and crisp treble, became apparent from the first few seconds.

The included microphone and media playback buttons worked flawlessly, allowing us to control our music both with Android and OS devices.

What’s in the Box?

SENSO generously gives you a long USB charging cable as well as a short USB charging cable. Included in the box is also a dual-port car adapter for charging on the go, carrying case, wire tie, and three sets of replaceable ear tips.
