Extended batteries offer extra hours of use per charge for your smartphone, something that – for many – is worth quite a bit.  Fortunately, if you’re a Samsung Galaxy S III owner, this benefit doesn’t have to cost much at all.

At $22, the QCell Samsung Galaxy S III Extended Battery Kit is a bargain.  For that price you get not only a 4200mAh Li-Ion battery (double the capacity of the included battery), but two replacement battery covers for the phone: one blue, one white. 

The battery is also NFC friendly, so you’re ready to go with Google Beam and Google Wallet – if you use either feature.

The Amazon.com reviews are glowing, with five out of five stars as of this writing.

Adopting new technology often requires compromise. In the case of Bluetooth headsets, we traded boring ol’ sound quality for ease of movement, freedom from cords, and a tech fantasy dating back to Lt. Uhura with a silver chess piece in her ear. In the early Bluetooth years, many made the trade and went about their lives with poor audio assuming – at some point – quality would catch up to convenience.

Fast-forward ten years, though, and the picture hasn’t changed as much as we might have hoped. While there are many more – and far better – Bluetooth headsets available today, half of the original tradeoff remains: while what the user hears has improved, sound quality on the other end of the “line” still leaves much to be desired.

For this reason, many steer clear of Bluetooth headsets, not wanting to subject family, friends, or business associates to audio dropouts or the “tin can” effect. I, too, have tried a number of wireless headsets, only to set them aside and return to the phone-between-ear-and-shoulder paradigm.

So, a few weeks ago, I decided to see if the tradeoff could be eliminated once and for all, or at least significantly mitigated. I would gather several Bluetooth headsets of a specific type – those with boom microphones that extend near the mouth for the best outgoing audio – and see if there is, at last, a Bluetooth headset that can offer bi-directional satisfaction. What I discovered was somewhat disappointing, but incredibly useful. Put another way, there are at least a couple of Bluetooth headsets available that offer phone-like sound quality, going or coming.

Unlike hard drive prices, the cost of microSD cards continue to fall.  In fact, you can now get a Class 2 SanDisk 16GB microSDHC memory card at Amazon.com for just $5.95 plus shipping. 

This is a fantastic deal, particularly considering that at big-box retail stores like Wal-Mart and Office Depot a 16GB microSD card can cost as much as $25 or $30. 

Price may change at any time.

OtterBox, maker of many popular ruggedized cases for smartphones, has introduced two new cases for the new Motorola Droid RAZR: the Droid RAZR Defender Series Case and the Droid RAZR Commuter Series Case.

The two cases are form fitted to the RAZR Android smartphone.  The Defender Series case (left) offers the most protection with three layers and includes a belt clip holster; the Commuter Series (right) has two layers of protection and lacks a holster.  The Defender is available only in black while the Commuter comes in your choice of black or blank and pink.

The MSRP for the two cases is $49 for the Defender and $34 for the Commuter.  Each case will begin shipping in the next few days.

Find out more at OtterBox.com.  Also, Amazon.com currently has each of the new cases for order for a few dollars below the MSRP (Defender $45, Commuter $28).
