Having a long soak in the bathtub might be relaxing, but there is nothing like music to make a good situation better, right? That's probably what the folks at Idea Label were thinking when they designed the Music Planet, a portable ball-shaped MP3 player that can float in your bath tub. Aside from its stereo speakers, the device certainly seems very useful, especially if you plan to sing while you take a long bath. It's currently only available in Japan, but you could probably import it, though at $120, it's not exactly the cheapest device in town, but it certainly seems fun and useful.

Specifications of the device include:
- FM tuner
- Alarm clock
- SD/SDHC card support
- USB support
- Powered by 6 AA batteries

Panasonic has launched a new stereo system designed to be used with Apple's iPhone and iPod Touch, the Panasonic D-Dock SC-H40. The Panasonic D-Dock SC-H40 features a slim design, measuring just 69mm thick at it thinnest part, and it features integrated speakers and a digital amplifier, plus a built in CD player. There is also an AM/FM tuner, plus an SD/SDHC/SDXC memory card slot, and a sliding door that you can hide your iPhone or iPod Touch behind. It comes with a remote which lets you control everything on the stereo and Bluetooth 2.1+EDR so your iPhone or iPod Touch doesn't need to be docked with the Panasonic D-Dock SC-H40 for you to play your favourite tunes. It also has a feature that lets you record from the AM/FM radio and transfer music from CDs to the memory cards in the SD card slot.

The Panasonic D-Dock SC-H40 will go on sale in Japan in March for around $420. There are no details as yet on when we are likely to see the Panasonic D-Dock SC-H40 in the US or Europe.

How about some solar sound to cheer your soul up? These black and white speakers are built just to do that, to cheer you up with the power of sunlight. Their lithium-ion batteries are charged by solar power using the solar panels on their bodies. And no need to worry as to what to do on the gloomy, sun-less days as they also feature a USB terminal.

What's more, it is possible to connect your iPod or other portable music devices through their stereo mini input. They measure 19.5x11.2x5cm, weigh 290g, and offer 2W x2ch audio output. Full battery charge provides 5-8 hours of continuous music playback.

Landport's speakers will be available in Japan this year as of late March for about 5,250 yen.

There are several problems with wireless charging mats, like Powermat's. For starters, they're expensive. They also have limited device support, and you often have to swap out the backplate of the device for a heavier custom one.

But if you want the benefits of a wireless charging mat without the price and bulking up of your gadgets, then you might be interested in taking a look at iDAPT's i2 and i3 chargers. They're not wireless, but don't hold that against them.

It's a mat, but out of that mat poke charging bases, which you then poke your devices into - they sit upright. There are tips for more than 3500 devices available - batteries, PSPs, the Nintendo DS, satnavs and - iDAPT claims - "almost every phone and mp3 player on the planet".

The i2 offers two charging ports with six of the most common tips, and the i3 will give you three charging ports with the same tips. They're available in black, silver and pink, and the i2 costs £20, with the i3 setting you back £30. Extra tips cost £6 and an AA/AAA battery charger tip costs £12. Available now.

The X-Tube AS301DTS is an interesting little device. A fake looking vacuum tube USB dongle that lets you enjoy DTS surround sound right on your laptop. It's powered by a VIA VT1610 chipset and is compatible with Windows XP, Vista or Windows 7.

If you want to get the full DTS effects, you'll want to use a pair of AH-516 headphones though. Otherwise why bother? The X-Tube AS301DTS will cost you around $44.

Either our hands have suddenly got a lot bigger, or a Korean manufacturer called Motz has built what might be the smallest, dinkiest, radio in the world. It measures just 1.45 x 0.75 x 1 inches.

It's made of wood, comes with an LED indicator, aerial, on-off switch and a button that lets you change stations. That's pretty much it. On the side is a 3.5mm jack that lets you use the device as a speaker for an mp3 player, or you could even hook up two with a splitter to give you stereo sound.

It has a built-in rechargeable battery, which you can pump up with a USB cable. At the moment it's not on sale outside of Korea, though, which means it'll set you back 39,800 Korean won - about £22. Expect to pay considerably more when you add on postage, though.

Announced earlier in October 2009, the C-IP313 mini Hi-Fi supporting SD/SDHC cards, USB, iPod (Via iPod dock), CDM, MP3 and WMA is now available in white and that's all.
