Pros: Does as it claims. Simple and intuitive. Controls Pandora on my phone and calls are voice command after pushing the phone button. Calls are clear and others can hear you fine. I don't have to take my phone out of my pocket anymore. Just get in and press play on the x3 and you are off. Charges my phone or whatever with USB. Clear music playback. Completely fixes radio only cars.

Cons: Doesn't spit out quite as strong an FM signal as I expected. You need to find a seriously dead station for it to be completely clear and accurate sound. I'd recommend doing this yourself because the x3 remembers when a previous auto frequency it choose it changed by asking for another, so it doesn't go back to that frequency again, even if it was more clear. My personal product came with cosmetic damage but that is not a fault of the product, just luck of the draw.

Pros: None

Cons: Couldn't cool an Intel 4004. This thing is useless. I installed the barbaric connections, started my computer up and to my shock this thing brought my temperature UP 20 degrees Celsius. Went straight up to 80 degrees Celsius on idle, up from 60. Did nothing, waste of money. DO NOT BUY - mark my words, you will regret it!

Pros: - Noctua quality and 6 year warranty. - NT-H1 thermal compound is better than most - Silent Operation - Cools CPUs with 85W TDP or less with ease.

Cons: - Top mounted fan is designed for desktop use only, not well suited for a 2u but will work in a pinch for a 3u server.

Overall Review: Best cooler at this size. Great for small but not true SFF builds.

Pros: * Half the price of Noctua * Silent operation * Decent airflow * Have about 8 going strong for 2 years now * Warranty is the same at 6 years

Cons: * Comes with just the fans and fan screws (Noctua has tons of useful accessories) * Warranty is the same but you probably will need to claim it as I don't see these lasting as long

Overall Review: * I would recommend to anyone who has a random 80mm spot in their rig or anyone running a 2U server. * Can't beat the price to performance/noise

Pros: Cannot say enough. Sound you have never heard from headphones unless you are a DJ -THX certification makes a huge play in the Bass which is rich, full, deep and loud... Bass you can feel -50mm driver means FULL range of sounds. treble is clear and not tingy, mids are strong and lows are powerful. -3D sound is not a gimmick. If it comes from 135 degrees to your left in the movie/game you will here it from exactly that direction. -Scout Mode is a must for my gaming now. You simply cannot sneak up on someone with scout mode. Every footstep is crystal clear. -Quad-core sound card deserves awards all on its owns. THX and Dolby professionally decoded into 7.2. Even has a 3.5mm/optical in multiport for any audio input. -Works flawlessly with PC, Xbox 360 and PS3 -Sound Blaster software is customization and very impactful in use. -8 Hour battery life is guaranteed. -Build quality I can only describe as 'Executive' -Mute and Volume buttons on headset and sound card. -Mic comes with wind screen and has software to make it sound full and rich to person on other end (really rare) -Full and rich without being incredibly loud. -Cannot hear anything else when you have these playing... (Tested in school construction zone) -Charges in about 2 hours -Can play while charging -Draws very little power

Cons: No stand. Sound card will only power up with higher power USB port (like computer or console or 2 amp wall adapter) No wall adapter included Price - but seriously worth every penny.

Pros: Sound is superb. Loud and clear. The stereo effect on this is wonderfully accurate. Pairs instantly and stays connected for about 35-40'. Buttons are well placed and responsive. 8 hour battery life claim is spot on. Fits well and stays secure on my little head. Phone and mic work very well. PPRRIICCEE! Picked this one up for 19 shipped, well worth 50. Foldable and has convenient case and charging cable. Well written user manual.

Cons: Build feels a bit cheap, like it may ware out if treated badly. Blue led on the right ear blinks in use and gets annoying in the dark because it is bright and only comes from the right side. Lights up the room intermittently. Nothing to take an egg off for.
