Logitech sent over Z-5 Omnidirectional notebook speakers. They're not going to put my Klipsch THX speakers of business (not by a long shot), but you need to remember that they're powered entirely via USB and don't take up too much desk space. Simplicity is clearly the goal here; the last USB-powered speakers I looked at, Altec Lansing's XT1's were designed with portability in mind. Compared to the XT1's, Logitech's Z-5's play extremely loud and sound extraordinary. They should make a great holiday gift for the notebook user who listens to music through fuzzy notebook speakers.
Logitech also sent over triple.fi 10 pro's from their recent Ultimate Ears acquisition, and I had them on hand at the recent Apple "Let's Rock" event, where I pitted them up against Apple's upcoming $79 in-ear headphones.
You get what you pay for - on both ends of the price spectrum. For $79, the Apple headphones sounded great - easily competitive with the low end of Shure and etymotic's range, and they blow away Bose's in-ear efforts (I can't comment on UE's entry level headphones, as I haven't listened to them). But they couldn't hold a candle - on bass or midrange - with the $399 UE's triple.fi 10 pro's. I was also annoyed that the Apple headphones are not fully compatible with the iPhone, just the iPod touch and new nano. (That new nano needs to be felt to be believed - it is vanishingly thin and the colors are gorgeous. Apple did a really nice job with this one.)
I'm really enjoying the triple.fi headphones, and finally had a chance to do some quick listening tests vs. one of their main competitors: Shure's $499 SE530. For natural, neutral sound quality, the SE530's are incredible, as well they should be at that price. The UE triple.fi 10 pro is a bit less neutral and seems to amp up the body of bass and warmth of the lower midrange - which is often lacking on headphones. Both are equally revealing, but I would describe the sound of the UE's as more "fun. Which is better? It's a matter of taste. While I suspect the Shure's are more accurate, listening to rock and pop with the UE's is more involving.
But my favorite headphones for the iPhone (and any phone with a 3.5mm jack, which includes most new RIM BlackBerries, Nokia's XpressMusic line, and select LG and Samsung phones) are still Shure's SE530's with the Shure iPhone microphone adapter, pictured below. They sound great with the compressed music you have on an iPhone, have the most comfortable shaped foam earplugs in the industry, and the modular design allows you to swap out various cord lengths or accessories.
