The Wireless Sports Headphones from 66 Audio deserve our full recommendation. The generous padding is supremely comfortable, despite the thin headband. Our only criticism concerns the bulky shape of the headphones. If you can get past this issue, you are looking at one of the best pairs of Bluetooth headphones currently available on the market.

66 Audio is an innovative manufacturer of audio equipment that’s meant to last and perform great under all conditions. Their Wireless Sports Headphones an affordable solution for all people who are looking for a way how to comfortably listening to their music on the go. Let’s take a look at what less than $50 can buy you.

Design and Build Quality

Take a look at some promotional pictures of the Wireless Sports Headphones and notice how thin the headband is. Bluetooth headphones usually have a sturdy headband to support the weight of the electronic components hidden inside. These headphones take a different approach: instead of making the headband larger, the manufacturer has decided to enlarge the earcups.

This results in a very lightweight construction, but it also can make the wearer look like a bug. This is especially apparent when someone is looking at you straight on. This isn’t a problem if you plan on using these headphones at home, but you might get a few weird looks from people on the street.

The headphones support multipoint pairing and real-time battery indication. Intuitive multifunction controls allow you to leave your phone in the pocket. You can adjust the volume, skip tracks, and use the intelligent MFC button to play your music, answer calls, and even initiate Siri or a similar voice assistant.

All these features are great, but nothing new under the sun, which is not something you can say about the battery life. On a full charge, these Bluetooth headphones are able to last for 25 hours of continuous music playback and over 400 hours in standby mode. All of this thanks to the built-in 400mAh rechargeable battery.

Sound Quality

Technology like CVC noise cancellation and Bluetooth 4.0 enables incredibly low latency and high bandwidth output with data rates up to 352kbps. In other words, these headphones aren’t anything like the ones you bought 5 or 10 years ago. Bluetooth has gone from something that was hardly usable for any serious music listening to being the absolute staple of portable listening.

But the audio signal is just one part of a much larger equation that determines the overall sound quality. We are happy to say that the 66 Audio Wireless Sports Headphones don’t disappoint even when it comes to the rest of the equation.

The headphones boast an impressive dynamic range and listening to music through them is a pure joy. Powerful bass can be found right next to crisp highs and thrilling mids. A combination like this is something you don’t find every day – especially when it comes to sub-$50 headphones.

We also want to mention the excellent call quality and clarity of these Bluetooth headphones. The manufacturer has not cut any corners and spent money on a proper omnidirectional microphone for optimal clarity and noise cancellation. The results speak for themselves.

What’s in the Box

The packaging includes a premium micro-fiber pouch, micro USB charging cable, user guide, and an impressive 1-year manufacturer’s warranty.
