Buy.com this week is offering the Cyanics portable swing speaker with built-in case for iPod touch first and second generation (model no. IPS-46) for only $26.99. This makes it $13 less than its previous list price of $39.99 and tied for the lowest cost we have seen for this speaker set. FREE shipping is included and sales tax applies for residents of New York and California.

Although the Cyanics portable case does hold a respectable rating amongst customers, there is one major flaw with the durability of its case which in turn makes the protection offered less than desirable. Delivering a little more protection is the equally recommended iMainGo 2 handheld speaker case for the iPhone and iPod touch, available for the higher price of $39.99 with FREE shipping included. Those of you who don’t require a case with their iPod speakers, check out the Altec Lansing inMotion portable speaker system with iPod dock. Located at Nextwarehouse.com for only $57.44, FREE shipping is also included. Or Kick it up a notch with the Boston Acoustics Horizon Duo-i speaker dock for iPod, available at thenerds.net for $129.99 and has shipping rates starting at $9.99.

The Cyanics portable swing speaker system comes with a crystal-clear protective case, a built-in rechargeable battery that can handle up-to 8 hours of music per-single charge, and a high-performance stereo system that sits at the back of the iPod. The speaker can be used wiith both the vertical or wide-screen view and can double as an iPod stand. It also provides access to most major iPod ports and comes with a headphone jack for private listening. Dimensions: (W) 2.625” x (H) 4.75” x (D) 0.75”; weight 2.5oz.
