Plantronics BackBeat Go 2 stereo Bluetooth headset review: Improved sound -- and now water-resistant

As with all in-ear headphones, some people will be able to get a better -- and more comfortable -- fit than others. I thought the earphones were pretty comfortable and didn't have a problem wearing them during my daily 30-minute commute to work. I was able to get a tight seal with the large ear tips and easily paired the headphone with both an iPhone 4S and a Samsung Galaxy S4, streaming music wirelessly from both devices with only minor hiccups. To be clear, while there's a cord that goes between the earpieces, these earphones don't plug into anything; they're indeed wireless and you can make calls with them.

Like the original BackBeat Go, the new model comes with little "stabilizers" to get a more secure fit. While they work pretty well, I think Plantronics could come up with better stabilizers that really keep the earphones in your ears even more securely, especially when you're running. For instance, I liked the stabilizers found on the Monster iSport Immersion and Audio Technica's SonicSport ATH-CKP500. However, both those are wired in-ear sports headphones.

As far as accessories go, these guys come with three different-size eartips, plus a USB charger. They're available in two colors -- white or black -- and there's a version that comes with a charging case for $99.99, or $20 more.

The idea behind the case is that it not only protects the earphones but it has a built-in rechargeable battery for charging on the go. When fully charged, the case can charge the headphones twice, which gets you up to 13 hours of battery life, though you won't be able to use the headphones while you're charging them. I personally thought the case could stand to be slightly larger to accommodate the headphones more easily (you really feel like you're stuffing them in there), but that's a small gripe.

The original BackBeat suffered from some performance issues, the biggest of which was that it didn't play very loudly (I felt I could have used more volume when I was outside on the noisy streets of New York).

I didn't have that problem with this model and overall, the sound was fuller and more dynamic, though I can't say it's incredibly open or detailed. The bass was pretty punchy, but again, if you fail to get a tight seal, the earphones will sound thin.

For those new to stereo Bluetooth, it's worth noting that Bluetooth does compress audio files and has a tendency to flatten out your music, leaving it sounding less dynamic. But Bluetooth headphones are getting better, and while this model doesn't feature the aptX codec, which can offer slightly improved Bluetooth sound quality with mobile devices that also feature aptX (no iPhone models have aptX, but many of the new Android models do), I thought it sounded good for a Bluetooth earphone at this price point. It's relatively natural-sounding, fairly well balanced, and lively. It may not satisfy the most critical listeners but it can hold its own with with a lot of wired in-ear headphones that are in the $30 to $70 range.

Comparing it with the significantly more expensive Jaybird BlueBuds X Bluetooth earphones ($169.99), the two models sound very similar. That model has a cord-management feature and claims better battery life, but it's not worth the extra dough.

As for call quality, Plantronics hasn't changed the microphone, and the performance of the headset was good (callers said they could hear me well, though it obviously helps to pull the microphone closer to your mouth).

It's challenge to design really small wireless Bluetooth earphones because you have to cram a battery and some extra electronics into a compact housing the size of something that's not much bigger than, well, an earbud. Plantronics' first-generation BackBeat Go was pretty good, but it did have a few rough spots, particularly with its performance.

Cosmetically at least, the BackBeat Go 2 really isn't different from the previous version, but with the tweaks in the design to the remote/microphone and the addition of the moisture-protection coating, there have been some notable improvements, though battery life still isn't great. But the most important change is to the sound quality -- it's right there with the sound quality of competing products such as the Jaybird Bluebuds X Bluetooth earphones, which retails for a good deal more.

While the Go 2 still has room for improvement (a little bit smaller design, better stabilizers, and better battery life), it's a nice step up from the original and strongly worth considering if you're looking for an earbud-style wireless headphone.
