Get Moving with the BackBeat FIT 305 Wireless Sweat-Proof Sport Earbuds

I’ve previously reviewed each of the various generations of Plantronics’ BackBeat GO wireless earbuds. When they announced the BackBeat FIT 305 Wireless Sweatproof Sport Earbuds, I was curious to see what Plantronics had done to make excellent wireless earbuds even better. Not only am I impressed but Raina was too. She asked if she could keep my review sample.

From Plantronics:

Enjoy big sound in a small package with the ultra-light and portable BackBeat FIT 300 series of wireless sport earbuds. A sweatproof coating protects the earbuds during workouts, while unique patent-pending, secure-fit eartips make them comfortable for all-day wearing.

The BackBeat FIT 300 series is designed for those who want to enjoy their music on the go. They are light, comfortable, get decent battery life and, thanks to an IPX5 rating, water-resistant.

The military-grade P2i nano-coating means these earbuds are ready for sweat, rain and whatever else you might throw at them.

Inside the box you get the BackBeat FIT 300, a micro USB charging cable, a quick-dry storage pouch, a clip to help keep the earphones stable and secure, small, medium and large ear tips and instructions. The ear clip is an especially nice touch since it not only stabilizes the earphone cord but also helps minimize the noise that might otherwise ride for the cord to your ears as the cord moves while walking or running.

The BackBeat FIT 300 deliver up to six hours of listening time, can maintain a connection up to 33 feet from the audio source, can hold a battery charge for up to six months when in deep sleep mode and weigh just 14 grams. All of this comes together and explains why Plantronics can claim:

You’re always in motion, and need your music to keep up. Portable and ultra-lightweight, these discreet wireless earbuds stay put during active use and take you comfortably from one place to the next.

What is so striking about the BackBeat FIT 300 is that they are so light but still able to get decent battery life. Moreover, it is striking how comfortable and secure the ear tip design is. You get three different sizes of tips and, after trying each size out, can be assured you will not only get a secure fit but you will also find them amazingly comfortable. The design of the tips allows the earbuds to sit flush in the ear. As Plantronics notes, “the patent-pending, occlusive ear tip design blocks out noise and stays secure during active use.” I much prefer the ear tip design of these earphones to the design used on their excellent BackBeat GO 3 earphones.

The cable is a graded cloth material that is thicker than that used on previous iterations of Plantronics earphones with this design. Not only is this “reflective sport-weave cable” tangle-proof, but it also has reflective material sewn into it, so you have increased visibility if you are running at night.

The electronics of the BackBeat FIT 300 is found in a small rectangular box a few inches from the right earbud. It not only houses the electronics and battery but has the volume controls, multifunction on/off/talk button and the microphone. The micro USB charging port is hidden beneath a small door on one side of this controller.

One might expect that having this electronics battery box on one side of the earphones and not the other might result in unbalance earphones. That’s where the “secure 2-in-1 cable clip” comes in. It prevents this from becoming an issue.

Perhaps most importantly, the Plantronics BackBeat FIT 305 sounds fantastic. I’m not hyperbolic when I write that. These earbuds are excellent. Moreover, since these are from Plantronics, it is no surprise that they are great for making and taking calls. The microphone is hidden in the inline controller, but it still delivers HD voice. I was impressed and, as noted previously, Raina was too. These are designed for active use but can easily serve as your on-the-go earbuds regardless of activity.
