Conclusion

If we're grading strictly on sound quality, the Logitech Z515 is a tough sell. If you're planning on paying $99 for a pair of speakers that will spend their useful life sitting at your desk, you can do a lot better. The Z515's an improvement on notebook speakers in any capacity, but if it's just going to be stationary throughout most of its life, you can do better with a pair of conventional computer speakers. Fortunately, we aren't grading strictly on sound quality.

The Z515 is clearly designed to be as portable as humanly possible, an effort to strike a balance between sound quality and mobility, and on that front they feel like much more of a success. Playback over the Z515 was perfectly fine for casual use, and with the volume cranked up it can definitely fill a room (and it does sound much better at higher volumes.) But it was meant to be on the move, as aptly demonstrated by the space for the receiver in the back and the black zipper case it comes with. Supporting three different methods of connectivity—wireless dongle, Bluetooth, and 3.5mm minijack—makes it as flexible as you could ask for, and the wireless range is outstanding.

Something else to consider is that with the USB wireless adapter, you're not saddled with the built-in audio on your laptop, and you don't need to use the headphone jack. We've encountered quite a few laptops over the years where the internal speakers and audio jacks both have a lot of electrical noise/interference. By going the USB audio route, Logitech eliminates that concern.

That's where you're really going to have to decide whether or not the $99 MSRP is worth it to you. If the flexibility and wireless range are attractive, I'm not sure where you can expect to find better on the market. As a strictly stationary speaker the pricetag is onerous, but under those circumstances you aren't using the Z515 as it was intended. I've been in situations where a pair of speakers like the Z515 (because it is essentially a pair of stereo speakers) would've been incredibly useful and worth their weight in gold, but it's going to be up to you to determine whether or not the Z515's mobility and flexibility are going to be relevant enough to make up for the $99 pricetag.

    Take a step back, Mr. Audiophile, and please note what the article is about: a laptop speaker replacement option. I don't care if you think Bose, Logitech, etc. are crap compared to expensive options, fine. Even the worst Bose/Logitech/Creative/etc. computer speaker kit sounds worlds better than the best laptop speakers I've encountered. Is the Z515 going to impress you? Obviously not, but the goal isn't to replace studio monitors or even inexpensive desktop speakers; the goal is to provide something that works and provides better sound than a laptop's built-in speakers.

    What you're doing is akin to me reviewing a netbook and showing how it compares in performance to a 15 pound desktop replacement that costs an order of magnitude more (and gets an order of magnitude less battery life).

    Rule of thumb for arguing about computer audio equipment comments:

    Any time you see OPAMPs mentioned (with some combination of obscure letters and numbers), and "mainstream" audio cards disparaged as "POS", it doesn't deserve your explanation. 99 out of 99 times it's just arrogant audiophile dogma speaking.

    LOLAUDIOPHOOL

    ABX tests proving the inferiority of those things you disparage, or be called out.

    If you are a movie fan, you wouldn't be watching movies on your laptop anyway. If you have access to a wall outlet, then you should have access to a desktop. I don't really see the point...

    As a business traveler, I could see a use for speakers like these. Stuck in an airport I'd use my headphones while watching a movie. Stuck in a hotel room without access to a DVD player, these speakers might be worthwhile.

    I'm a movie buff and a filmmaker, but when I'm away from home I don't have the luxury of relaxing in front of my HDTV, so I use my laptop. And a LOT of college students are in the same situation: a 42" HDTV isn't going to fit in a dorm room.

    I think a genuine movie fan isn't going to care that much about what they watch their movies on (iPhone/iPad notwithstanding) so long as they can comfortably enjoy the material.

    Surprised the warranted a review, they're just another consumer crappy audio product that doesn't deliver.

    We review what we're sent. If you only want to read positive reviews, I recommend PC World or CNet.

    Even in CNET, they recommend to for the cheaper Creative D100 instead.
    Other alternatives: BlueAnt M1 (Supertooth Blaster "Disco" in Europe) and Creative D200.
    I think that the only major drawback in these other alternatives is their exclusive Bluetooth wireless connectivity with more limited range. In contrast, I find replaceable batteries a more convenient option in case you don't have access to electric power for several days.

    The battery issue seems too much of an inconvenience, IMHO. This seems better, at less than half the price: http://tinyurl.com/292gq4e

    Dustin, have you heard the legendary Klipsch Promedia? The 2.1 doesn't cost that much more than the Bose Companion 2 Series II, and it's probably a world of a difference. Especially if you set up the speakers at least 5ft away or against the wall, spread out. Base is tight and controlled. I know that Bose sounds decent, but when it comes down to it, it's a 15W 2.0 system compared to 200W 2.1.
