| If you want to use the device as a phone you must use an earbud and microphone, and you get about 1 hour of talk-time. |
| This month Jawbone will release a series of earbud replacements, which are designed to fit so snugly that you will not need an earloop. |
| In our tests, we found that the earbud wasn't exactly the most comfortable fit and took a while to get used to, but once we removed our ear accoutrement, it fit like a glove. |
| Aside from skin-based monitoring, there will also be an accelerometer included in the earbud chassis. |
| The original BackBeat Go headphones were among the maiden wireless earbud products launched in the market and the second generation model has arrived more than a year later. |
| Our phone also has a stereo earbud set in addition to the ringtone speaker, so the difference is really heard when the user listens through them. |
