New York - Monster on Tuesday filled in the details on its previously announced new Clarity HD sub-brand and stuck its foot firmly in the 3D market with a pair of universal active-shutter glasses.

Head monster Noel Lee appeared at the Consumer Electronics Association Line Shows event and debuted new headphones, home entertainment loudspeaker solutions, docking speakers, cables and cleaning products, among others.

Monster's first 3D glasses, Monstervision Max 3D, are compatible with any brand 3D TV and boast built-in RF technology to avoid the common problem of IR interference that can plague existing active-shutter glasses. The RF transmitter allows for the system to expand to be paired with thousands of Monstervision brand glasses, Lee said.

Proprietary active-sync software is embedded in the transmitter and receiver to prevent sync loss and pairing drops. The glasses are rechargeable and offer more than 800 hours of use in a single charge, Lee said.

The glasses were designed to fit over a user's existing prescription eyeglasses.

The glasses are expected to ship in August. A bundle of one pair with RF transmitter will have a suggested retail price of $249, with extra glasses available for $169 each and an extra transmitter for $59.95.

Lee said an expanded line of Monstervision glasses, in various colors and styles "designed by some of the most famous designers in the eyewear industry," will become available later this year.

Monster's Clarity HD line debuted with a new set of ear buds, which Lee said "resolves incredibly low-level detail. They are great for classical music," Lee told TWICE. "If you like hearing the sound of the bow drawing across the neck or fingers sliding down strings, these are ideal." He likened them to "a magnifying glass for your music."

The ear buds include Control Talk technology for iPhones and will have a suggested retail of $229.

Also in the Clarity HD line are two Bluetooth portable speakers for handheld devices, the black Clarity HD Precision Micro Bluetooth speaker ($119), for use with Blackberry devices, smartphones and notebook PCs, and the silver iClarity HD Precision Micro Bluetooth speaker (also $119), for use with iPod, iPhone and iPad.

The ultra-compact form factor devices deliver Bluetooth 2.0 HD audio, which Monster combines with audio and digital signal processing for clarity. Built-in microphones allow for hands-free dialing, and lithium-ion batteries provide up to five hours of listening on a single charge.

The two systems boast dual 35mm full-range drivers and a passive radiator subwoofer design for clarity and powerful low frequency bass response, the company said.

Wireless music streaming is made possible by coupling advanced audio distribution profile (A2DP) with audio video remote control profile (AVRCP) for wireless audio and video playback control. The speakers may also be used with a wired connection using a standard 3.5mm headphone port.

At the top of the Clarity HD line is the Executive speaker series with accompanying iPod dock, a complete desktop audio system powered by a built-in 75 watt-per-channel amplifier. Each 12-inch by 6-inch by 6-inch speaker features a 5.25-inch polypropylene woofer, a 1-inch silk dome tweeter and low-resonance cabinets with bi-amp design.

The system is voiced for high-resolution digital media playback and time-aligned for linear response. Precision crossovers provide detailed sound staging, Lee said, adding that the system's master/slave configuration allows for simple installation and setup.

The included Executive-series iPod dock has a built-in master volume control and a full-function IR remote control. The dock includes an auxiliary audio input that allows playback from other digital audio devices.

The system will retail for $449.95.

The company also showed a new iPad Cleaning kit, an addition to its line of Outlets To Go laptop power adapters, and announced that its SuperTip ear bud tips, originally included with Monster's Turbine Pro earphones, will be available as a stand-alone product for use with any brand ear bud.

Also on display was a pair of the recently announced TRON headphones, co-developed with Walt Disney Pictures. Details are available here.
