usb headphone amps

"Great DAC...Great DAC....If you're looking for an inexpensive headphone amp to give your music and podcasts a boost in fidelity, this is the product for you!...There is also a new Dragonfly Red that uses a more advance DAC with higher power output and a more controlled 1 step = 1 decibel volume control"

"Oh, what a match made in heaven !...a wonderful amp for all your headphones...No regret, just pure joy for my purchase."

"Good job Sennheiser....Works Better than I expected...-I do sometimes accidentally hit one of the bottom quick setting keys, but having them there does more good than harm....-The "hover" feature is a nice added touch."

""

"Very good sound quality, good build, too pricey...You can get a cheaper sound card that gives you great sound quality....I'll say though, if you want a very easy way to switch between speakers and a headset, this is a very convenient way to do it....This did the job perfectly as it was paired with a Sennheiser G4ME ZERO headset and a small Insignia Mini Soundbar."

"So Cool...Love it...Putting this amp on your sound bar is like owning a sports car and finding out its a transformer you go from a great sounding system to an amazing sound and system well worth the investment...I also like that you can use this amp in s 5.1 playbar or playbase system (although the setup is a little more involved than adding a pair of Play 1's for surround, but not hard)."

"Love it...Da bomb!...Got my 1200 watt class D amp about 2 months ago with my 2 kicker comp Rs 12" and they hit great with this amp and it's reliable and hasn't overheated on me even on rather warm days...my 2 12" kickers hit very hard... had to stop playing them for a while because I brought a new car which the sub box couldn't fit in so I ordered a custom box and I'm having it installed in a few days but with new Infinity Kappa 12" subs can't wait to here them with this amp."

""

"love it...Not bad...Good amp for a starter system, I suggest pairing it with a single type s 4 ohm DVC subwoofer in a ported enclosure....Only one issue I found, the Crutchfield website lists the amp able to handle a 1ohm load where Alpines does not show the spec so I sent a question to Alpine on Facebook to clarify the difference in data between the 2 sites!"

"No mess....good kit...I was pro wing together an amp I already owned with a subwoofer I was purchasing in store and this was a great match the pull the two together....great for a basic car stereo system, I plan on upgrading when I get a bigger system, for now this works good."

""

"It's ok...love it...It has some good low volume bass but you cant crank it to get more bass it simply levels off or fades to less power/ this amp has good clean rumble but lacks in punch /i had the alpine mrv-500 recently with a 12 memphis and that amp had some raw power at 2 ohms tons of punch it hit hard until the amp blew its fuses and smoke the sub with no explanation never worked since it was only a few months old...I have this amp hooked up with a JL 12" that can pack a serious punch and this amp handles it great."

""

"Love it...Good kit...This install kit was a huge improvement to my system & I would certainly purchase this product again in the future as opposed to paying for the name on the higher priced kits....Easy to use, way cheaper than the kicker amp kit, I used one in my truck and car"

""

"Love it...Love it....This is a great amplifier if you are looking to beef up a factory system a little....Great amp for door speakers atleast that's what I used them for kicker is a great product"

""

"Love it...Love it!...love this amp as it small and eay to tuck under a seat so no one can see it...I drive an hr and a half for work everyday and the amp doesn't over heat and keeps the tunes bumping... Great purchase for the price and the output of the amp"

""

"Love it...Love it!...I did have a bad ground location, but drilled a new one and cleaned the paint and primer off so it plays a bit louder, but not as loud as I want sometimes before it cuts out....I bought this amp with the 2 12 kicker cvr 1000 max rms and 2000 total and have blown 15 pairs of speakers the amp slams and some sounds and others with low bass is straight locks out I've done ever thing new wiring bigger cap otimal battery and bigger alternator And they are still blowing they checked it and the amp is bridged half up and still blows Buy geek squad protection so if it blows u can take back"

""

"Love it...Nice amp...This amp also has 2 speaker terminals even though it's a mono amp for more flexibility, variable frequency adjustment, variable bass boost and it's a class d amp....There is more than enough power and it's also a great amp for a truck when your limited on space."
