Once upon a time if you wanted to use your phone hands-free you were forced to look like an extra from Star Trek with an unwieldy earpiece hanging from your head. However, there are now some seriously sleek options out there.

Have a look below for our quintet of cool cellphone headsets, and let us know in the comments which ones you wouldn’t be ashamed to be seen wearing out and about.

1. Plantronics Discovery 975

---

Gorgeously minimal, Plantronics’ Discovery 975 is ideal for anyone looking for a particularly elegant solution for wireless cellphone conversations. Striking in its simplicity, the 975 is more than just good looking — its carry case conveniently charges the earpiece, a clever design that means you can juice up on the go.

2. Motorola Oasis

---

Boasting all day comfort, the Oasis is no slouch in the looks department, with a modern black and chrome finish and a tidy, behind-the-ear design. Motorola claims the Oasis is the lightest headset available, but it still manages to pack in voice prompt commands, dual-mics for noise cancellation and the ability to pair with two Bluetooth devices at the same time.

Cost: $79.99

3. Jawbone Icon

---

Jawbone makes hip headsets for the cool kids. The Icon is the company’s flagship model (in Jawbone’s words, “simply the best friggin’ headset on the planet”). It’s available in 10 unique styles, all of which are cool and contemporary. The gadget also comes with seven different earbud options, so it’s safe to say you’ll almost certainly find a combination to suit your taste.

4. BlueAnt Q2

---

With a classic design, the Q2’s simple good looks are backed up by some serious technology. This high-end headset won’t draw unnecessary attention to itself, yet it will offer you comprehensive voice recognition commands and text-to-speech technology that announces the names of incoming callers and reads aloud SMS messages. You can get all of that wonderful Star Trek tech with none of its clunky looks.

5. Jabra Stone

---

Arguably the most dramatic design on this list, Jabra’s Stone headset is about as far removed from your standard wireless Bluetooth accessory as you can get. The Stone boasts cool, curvaceous looks, as well as a portable charging unit that the headset slots neatly into, and it is available in both black and white. If you want to stand out from the crowd, the Stone is a rocking option for you.

In a bold restructuring move, Motorola is giving mobile technology a new emphasis in the company’s present and future.

Effective January 4, 2011, Motorola, Inc. will become two separate companies: Motorola Solutions, Inc. and Motorola Mobility Holdings, Inc. Following the split, the company’s current co-CEOs, Greg Brown and Sanjay Jha, will head up Motorola Solutions and Motorola Mobility, respectively.

This company restructuring comes along with a stock restructuring. Current shareholders will get one share of Motorola Solutions stock per seven Motorola, Inc. shares and one share of Mobility stock per eight shares. Motorola Solutions will be home to the infrastructure businesses while Motorola Mobility will be the one focused on mobile phones and consumer devices.A split like this has been in the works since at least 2008.

We’re going to make a wildly speculative guess and suggest that the blockbuster success of the Motorola Droid has had something to do with the company’s growth in the mobile sector.

Various models of the Droid have been so popular they’ve been hard to find in stores. Over the summer, the company’s Android ()-powered devices were selling faster than they could be built.

In fact, the Android platform has been a huge boost to Motorola’s success ever since the original Droid launched almost one year ago, when the company moved a healthy quarter of a million units during the first week of sales.

Motorola hadn’t had a device that big since the pre-smartphone Razr from 2004. With its robust and successful line of Android devices — and who knows, possibly a tablet or two in the future — we’re looking forward to what Motorola Mobility will deliver in 2011.
