Marantz, maker of high-end audio products, passed a new version of their IS301 wireless iPod dock through the FCC today.  The Bluetooth-powered system includes a Bluetooth receiver that connects to an AV system via component, composite or S-Video cables.  iPod/iPhones can then be placed in the wired dock, below left, or connected wirelessly through Marantz’s wireless transmitter (below, right).  Users can also connect directly to the IS301 receiver via Bluetooth with any A2DP compliant device.

When connected through the wired dock, the IS301 system can output video.  However, only audio output is available when devices are connected wirelessly.

We like the appearance of the sleek, brushed aluminum receiver.  The wireless transmitter is also a plus for users of iPods that lack Bluetooth.

However, the IS301 system sells for a pricey $250 – not cheap considering all the wireless iPod options available today.

Bluetooth headsets can be uncomfortable, difficult to use and unsightly.  SiZEN Corporation hopes to solve those shortcomings with the Slim speaker BT Cap – a baseball-style cap with an integrated Bluetooth receiver, mic, speaker and headset.

The cap relies on a tiny ‘brainbox’ that hides under the material in the cap’s front.  The brainbox receives Bluetooth signals, and can pipe audio to a slim speaker that is hidden in the bill of the cap, or a 3.5mm headphone connector.  Call and music control buttons are also placed on the cap’s bill, enabling users to easily manage calls or music playback.

While the Slim speaker BT Cap will place you in the upper echelon of geekdom, it does offer a number of benefits over the traditional Bluetooth headset.  Sure, you can’t wear a cap everywhere, but we love the idea of having a Bluetooth speaker in the bill of our caps while walking or biking.

Stereo Bluetooth headsets are great for a single listener, but what if you’re in a sharing mood?  Enter the U Needs UD-3000TV Bluetooth adapter.

Just plug in a SPDIF or 3.5mm audio source into the UD-3000TV and you can share your audio source with up to two Bluetooth devices.  Each device has a separate pairing button, so you can pair or unpair devices without disturbing other listeners.

The UD-3000TV only weights 2.8 ounces, making it a good option for portable listening.  The device has an internal battery that charges via USB, although U Needs doesn’t give any indication of battery life.  We’d guess that the battery life of the UD-3000TV will be much shorter if the device is connected to two Bluetooth devices at the same time.

It doesn’t appear that U Needs has a strong presence in the US, so this device will likely be imported through U Needs’ channel partners.  No word on pricing or availability.

While Shen Zhen Sailing Electronic Co isn’t exactly a well-known company in the US, the company’s Bluetooth Car MP4 device does seem like a solid Bluetooth handsfree kit.  The device attaches to your cigarette lighter, and has a complete range of Bluetooth handsfree features, as well as an SD-based MP3/WMA player and FM transmitter.

If you want to take your calls private, the Bluetooth Car MP4 also has a dockable Bluetooth headset.  That’s a convenient feature that reduces the number of Bluetooth devices lying around that need to be recharged.

No word on pricing or availability, but we’re suspecting that Shen Zhen Sailing Electronic Co. will rebrand the Bluetooth Car MP4 before it comes to the US.

Most Bluetooth headsets rely on a tiny microphone that must pick you your voice while filtering out background noise.  In most cases, this doesn’t work very well, especially in noisy or windy conditions.

Enter BonSayON.  The company’s S102 sunglasses use a NeoV Nasal bone conduction microphone that actually allows you to speak through your nose.

Bone conduction technology senses sound through vibrations in your bones, not through the air like normal mics.  This technology is ideal for Bluetooth headsets, since your voice can be easily detected through bone vibrations without interference from background noise.

BonSayON puts bone conduction sensors in the nose pads of the S102, while earphones are placed at the end of each earpiece (below).  This design allows the S102 to keep a relatively slim form factor, while completely eliminating the boom mic present on many Bluetooth headsets today.

While it’s a bit impractical to have to put on your sunglasses every time you want to speak on the phone, BonSayON did do a great job designing the S102s.  It seems like you can actually wear the S102s without looking like, say, Dog the Bounty Hunter.

Unfortunately, BonSayON doesn’t appear to have much of a presence in the US, and their website is still under construction.  But we look forward to trying these out if and when they reach the States.

It’s a pain to have both a mobile phone and a landline.  People trying to get in touch with you have to call two numbers and you need to check two voicemail boxes in order to find important messages.  Wouldn’t it be great if you could just turn your mobile phone into a landline while you’re at home?

Enter Nuvelli.  The company’s NUV1500 device turns your Bluetooth-capable mobile phone into a landline, giving you the convenience of a landline while at home without the hassle of two separate numbers.

To use the NUV1500, you first pair the device with a Bluetooth mobile phone – a simple, one button operation.  Next, you plug your landline into the NUV1500 via RJ11 cable.  You can also connect the NUV1500 to your existing phone system, which will enable you to connect several phones to the device.

When you receive a call, your mobile phone and all landlines connected to the NUV1500 will ring simultaneously.  The NUV1500 also supports features like caller ID and call waiting on landlines.  Conversely, you can place calls from any landline, and these calls will be routed through your mobile phone.

The NUV1500 looks great as well – the device is compact and has a shiny black exterior that won’t look bad on your desk or in your living room.

No word on pricing of availability, but Nuvelli does have a couple of distribution offices in the US, so the NUV1500 should be easy to find once it’s released.

This thin stereo Bluetooth headset from Sony Ericsson called the MW600, passed through the FCC today.  The device has a universal 3.5mm jack – a feature we love because it allows you to use your favorite pair of earphones.  The device also has a mini USB charger, so you’re not forced to lug around a proprietary AC adapter.

Interesting, the MW600 has an integrated AM/FM tuner, as well.  This is actually a pretty valuable feature when you’re working out, since many gyms broadcast the audio from public TVs over FM channels.

The MW600 measures 17.5mm x 15mm x 62mm, and weighs only 13g.  The battery supports up to 8.5 hours of music streaming, 11 hours of talk time, or 500 hours of standby.  Music and call data on the MW600 are displayed on a small, single color OLED screen.

Overall, we like the sleek, compact design of the MW600, as well as Sony Ericsson’s intelligent design.  We don’t have pricing or a release date, but the MW600 should be coming soon.

Handsfree systems are particularly important on motorcycles, and Cardo Systems, Inc. seems like they have a decent solution here with their scala rider TeamSet Pro.  The device features a boom mic and speakers that attach to the inside of a motorcycle helmet, allowing you to connect to your mobile phone, GPS unit or media player via Bluetooth.  The device also allows you to talk with other riders via an intercom system.

No word on pricing or availability, but Cardo has a pretty solid network of distributors in the US, so you shouldn’t have a problem finding this device when it’s released.

The aptly-named Tubular Wireless Speaker from IPEVO, pictured above, passed through the FCC today.  I’ve seen a growing number of speakers with this design, and I have to say it looks intriguing.

With support for A2DP Bluetooth, the Tubular Wireless Speaker can play stereo audio from your Bluetooth-enabled media player.  The device can also be used as a Bluetooth speaker when paired with a mobile phone.

The Tubular Wireless Speaker is battery powered, making it ideal for portable applications.  The device also hides a USB charging cord in one end – a great design choice that will make it much easier to recharge the speaker.

No word on pricing or availability.  We also wouldn’t be surprised if this is re-branded before it reaches the States.

This tiny MP3 player/Bluetooth headset from i.Tech, called the MusicClip 803, made an appearance on the FCC today.  The device seems like a slight upgrade from the MusicClip 802 that we spotted in October.

As a Bluetooth headset, the MusicClip 803 offers handy features, like support for any 3.5mm headset, an OLED display for viewing caller data, and a full host of call/music controls.  Additionally, the MusicClip 803 has 2GB of internal storage, allowing the device to act as an MP3 player.  An FM player is included as well.

The MusicClip 803 charges via its headphone jack, just like an iPod Shuffle.  The device provides 6 hours of talk time, 10 hours of music playing time, and 120 hours of standby.

All things considered, i.Tech packed a ton of features into this 16 gram device.  No word yet on pricing or availability, but i.Tech has a decent presence in the states so we should be seeing this soon.
