Unlike other electronic massagers with tangled wires that resemble medieval torture devices, the iGoGo is a tidy, wireless package that combines the swish looks of an MP3 player and the much-needed simplicity of a massage therapy device.

Design
Available in trendy white and sleek black, the iGoGo sports a gleaming top panel that slightly overlaps the back casing for a seamless layout of the unit's physical controls. An external MMC card slot is positioned discreetly on the right, while the audio, power and USB input jacks are tucked neatly on the underside of the unit.

Though larger than most standalone MP3 players (128 x 75 x 16mm), the iGoGo is sturdy and comfortable for two-handed use.

The iGoGo is accompanied by two matching massager modules that connects via RF wireless technology. The main unit can support up to four of these chic, bite-sized massagers (60 x 45 x 16mm) at a time. Affix them to the reusable, adhesive Hydro Gel pads and their stylishness alone will take your mind off that neck ache.

Functionality wise, the iGoGo plays it safe and simple with a standard selection of controls (play/pause, previous, next, power/stop, volume buttons) for the MP3 and Massage modes. The long, silver control buttons outlining the top of the unit are responsive and tactile, and the Music Synchronization button near the bottom emits a cool, blue glow upon activation.

One would expect the iGoGo to house a visually stunning navigational menu to complement its glossy exterior, but instead, the unit employs a disappointingly monochromatic interface. It's odd for a device devoted to holistic, sensory stimulation to neglect the visual aspect of music therapy.

Regardless, the iGoGo's LCD screen is plenty bright and crisp even under natural sunlight, and its bare-boned structure is a cinch to navigate.

Features
Despite being positioned as an MP3 player with massage functions, the iGoGo has no pretensions to being an iPod killer. Aside from five preset equalizers and a bass/treble control, don't expect to find any games, voice recorders or FM functions in this baby. Its music capabilities are strictly skin deep.

The iGoGo's main pull is undeniably its massage features and the synchronized music massage technology. The technology works by converting music frequencies into electrical pulsations, and using it to stimulate muscle contraction. The iGoGo also offers a range of regular massage therapy programs for the toning of problem areas, the stimulation of the nerves and the relaxation of stiff shoulders.

While the iGoGo's dismal built-in memory of 128MB can barely accommodate 30 songs, users have th e option of expanding their playlists with MMC cards of up to 512MB. It's a shame, however, that larger data storage options like SD and CompactFlash memory cards were overlooked.

The iGoGo plays only MP3 files and lacks accompanying software for the conversion or management of music files. It registers as a storage device when connected to the computer for drag and drop music file transfers via USB.

While the iGoGo is best enjoyed in the comfort of your home or office, road warriors can stash the unit and its massagers into the bundled black carrying pouch for those red-eye flights. Users are also better off using their favorite set of earphones with the iGoGo as the bundled pair is unsightly and delivers poor audio quality.

Performance
The iGoGo's massage offerings include three manual massage modes (Tap, Modulate and Knead) and seven programmed massage modes (Morning, Night, Trim, Relax, Cellulite, Back and Shoulder). There are also three built-in musical compositions to induce different massage sensations--unwind, Relax and Refresh.

Ironically, users may find themselves more relaxed before tinkering with the iGoGo's complex manual setup. While the wireless pairing of the main unit and the massagers is a good idea, the process proved tricky, no thanks to its unstable and frustratingly slow RF wireless connectivity.

The massagers suffered from frequent connection drops and troubleshooting these hiccups was made even more difficult when they power down automatically after three minutes of inactivity. At times, both massagers would respond to just one wireless signal, making it impossible to tweak their settings individually.

After much trial and error, the kinks were ironed out and the rhythmic vibrations of the iGoGo took over for a truly blissful and relaxing massage experience. A thinner hide may be required to tell the difference between the various massage programs, but the music synchronized massage provided an uplifting buzz that was exceptionally in tune with the uploaded tracks.

The iGoGo delivered decent audio quality, but tracks were given a new lease of life when played in orchestrate with the massage function. Auditioned with a pair of Shure E3c earphones, the well-rounded, boomy lows of Frou Frou's Psychobabble echoed the sweet pulsations of the massager while Mary J. Blige's Be Without You lulled with its reverberating depth.

The hydro gel pads we tested with the massagers retained their adhesive quality even after a good handful of sessions, after which they can detached from the skin easily with the weight of the massagers. Storage of the hydro gel pads on the bundled plastic holder will ensure adhesive maintenance for a longer period.

Looping 512MB worth of MP3 files with the massage enabled, the iGoGo fell short of its rated 8 hours of battery life with a result of 7 hours 13 minutes. Regular MP3 playback without the kneading hands saw the device outperforming itself at 9 hours 28 minutes.
