It's been a while since I posted a review of anything. Mostly I've been busy with work and projects, but part of this is the fact that I don't like reviewing things until I've been using them for a while.
Since my old LG Tone headset died, I've been using a Sony unit with the Apple EarPods and a Plantronics BackBeat Go 2. Neither was quite satisfactory though, so I've continued to look for an option that would work well. And I think I finally found one.
For about a month now I have been using a Plantronics M70. This is a single ear piece, with a soft gel hook and an optional over the ear loop. I've found that the over ear loop makes it slightly more secure, but uncomfortable with my glasses. Fortunately the ear hook actually holds it in much better than I'd expect.
As far as comfort, it's not bad. It has a little weight, but nothing actually annoying. (I frequently forget that I'm wearing it until I wander too far from my phone.) This model sits outside the ear canal, with the gel hook tucked under one of the folds of the ear. I actually like the feel and fit a lot.
Audio quality is passable. It's fine for voice and podcasts, but does get considerable distortion at high volume. The biggest annoyance I have here is that "s" sounds are a bit too high and tend to be grating. Lowering the volume helps though.
Outgoing quality seems to be ok. I don't talk on the phone much, but no one has complained to me yet.
The M70 does support A2DP, but music controls are limited. You can control volume, and go to the next or previous track by holding down the volume up or down controls. To play or pause, you need to press and hold both volume buttons for a short time. (I wish there was better control on this, but at least it works).
My favorite aspect is the battery life. It easily gets 8-9 hours of podcast playback, and I seldom need to recharge it before my phones battery dies. This is much better than the BackBeat Go 2, which seldom gets more than four hours, and also beats the Sony unit at around 6-8 hours. It's on par with my old LG Tone, and I'm quite happy with it.
Would I recommend this? Yes. It's not too expensive (under $40), feels pretty comfortable, has great battery life, and sound is acceptable. I've actually purchased two so I'll always have at least one ready to go.
