The Libratone ZIPP wireless speaker ($299) has as good a sound as any wireless speaker I’ve heard, if not the best.

I figured the sound was good coming from the desktop Wi-Fi speaker (10.3-inches high, by 4.8-inches in diameter) just because of the price and looks. I have been fooled by that theory many times, but not in this case.

The words that came to me instantly when I had only one of the speakers playing was “powerful and crisp” sound at any volume level.

I had these cranking with a pair of speakers, but if you really want to blow the roof off you can connect up to 6 speakers with SoundSpace Link, which obviously would be ideal to spread around a house.

Inside the 100 watt speaker, which delivers 360-degree sound, is a 4-inch neodymium woofer, two 1-inch soft dome neodymium tweeters and two 4-inch low frequency radiators

I set the speakers up to work with Wi-Fi, they also work on Bluetooth, USB, Apple Airplay, Spotify Connect or a direct 3.5 mm wired connection.

The speakers are controlled with a touch interface on a circular panel, set up with the Libratone app. Noise isolating microphones are inside to use the ZIPP as a speakerphone.

In addition to the great sound, the speakers have an attractive design, with a mesh fabric cover available in 4 colors. Additional colors can be purchased for $29 for an instant change of appearance.

You’ll get 8-10 hours battery life before a charge is needed. A built-in leather strap gives you the option to hang the speaker.

A little smaller 8.8-inch tall 60 watt Zipp Mini is also available ($249)

The Griffin Technology Tracker Clip for Fitbit is a stylish spring-steel clip, which slides securely onto clothing.

The packaging shows it works nicely as a tie clip, but you can clip it most anywhere to help keep track of daily activities and health monitoring.

It’s built with a fine mesh outer layer to let the Fitbit display show through, while keeping the activity tracker discrete or front and center on your clothing.

The Griffin Tracker clip is compatible with Fitbit Flex and Fitbit One.

The Toshiba TransferJet transfers digital files between devices such as smartphones/tablets and computers with ease.

With transfer speeds up to 560Mbps, the thumbnail sized devices network together wirelessly, without the internet.

I tried out the USB/MicroUSB wireless adapter; one piece has a standard USB connection, while the other has MicroUSB connection for smartphones and tablets.

Once you download the TransferJet App, devices can be paired instantly.

The wireless feature only works when the devices being connected are close together, which is a great thing. This minimizes the chances for data leak and ensures you know where your files are going.

TransferJet also has connections for Apple Lighting devices and SDHC memory cards for digital cameras. Each piece is powered from the device it’s connected to and has low power consumption so you don’t drain the device’s battery while in use.

The wireless adapters are available individually or in bundle packs.
