Reviews around look (5.00 of 5)
-
The look of the blew lights on top of the tubes orange glow is very nice
-
I also wish the line-in was on the rear, just for a cleaner look.
-
Aesthetically it looks great, the blue lighting from below the tubes compliments and offsets the orange tube glow nicely, and the gold colored front panel and volune knob are very sharp looking
-
I love the retro look and feel of the Nobsound Headphone amp.
-
below that is a Blue LED for each to compliment the look?

Reviews around price (5.00 of 5)
-
nice improvement on your Audio system at reasonable price.
-
I would have paid more than $50 for this, so I think this is a great price for such a sturdily and well-made device
-
Overall, I'd recommend this for being at the right price point, pleasant to set up, and looks great on the desk.
-
All in all, this little headphone amp does exactly what it's designed to do, and at a nice price, too!
-
Bottom line: solid construction, cool retro aesthetic, and great sound at an affordable price

Reviews around volume (4.49 of 5)
-
The volume on this is great, and it doesn't get distorted
-
Amazing sound quality and comfortable listening volume is at about half for me
-
Sounds OKLooks coolLogarithmic volume control (easy to modulate low volumes)Seems quite
-
They match up really nice and the volume is really loud at just half way
-
And when you turn to 5 o’clock on Bravo, it did gain volume more, but it starts distortion, and I don’t like how the music sound like that

Reviews around amplifier (4.45 of 5)
-
Great little amplifier, and it works well with both headphones and a 2.1 desktop speaker system as well.
-
Great little tube amplifier, makes a difference with the iPad listening thru my Philips X2/27 Fidelio cans
-
I enjoy the way this amplifier looks as well, the glowing tubes are very pleasing to the eye
-
This is a great head phone amplifier, but getting the tubes in was really, really hard hard
-
I am so convinced now that I am getting rid of my solid state stereo pre-amplifier and will be purchasing a nice vacuum tube stereo amplifier.

Reviews around quality (4.24 of 5)
-
The quality of sound and volume improvement for the price will be hard to beat.
-
I am currently running 6688s, much better quality and sound.
-
I know it's priced low, but I was still expecting better sound quality.
-
I have been rather interested in trying this amp out with with Soviet era vacuum tubes and I was shocked as to how good they make this amp

This little amp has good quality sound and is pretty loud

Reviews around thing (4.14 of 5)
-
Anyone rating this product that comes on here claiming to be an audiophile and proceeding to bash the product because it is not up to audiophile standards or because the tubes are just there as a pre filter and not part of the amplification should find better things to do with their time
-
And the good thing about Logitech is they are Bluetooth and easy to re-pair to other devices
-
n’t go wrong on any of it
-
Tried this unit out and it has some good things and bad
-
junkThis is the best purchase of the year!It's a simple little tube pre-amp, but wow this thing opens up the soundstage and warms it up with a good headset

Reviews around state (4.10 of 5)
-
in depth YouTube "teardowns" torture four about 24 hours as stated earlier
-
The power output section is solid state so it isn't a true push/pull tube device
-
This is essentially a waaaaaaaaay overpriced 1W solid state amp with tubes for looks
-
Defiantly adds some tube sound yet has the power of a solid state headphone amp

Reviews around way (3.70 of 5)
-
Best way to enhance your music listening for around $50 that I know of.
-
This was a good way to reduce the power load on my computer and increase my volume.
-
This item will only amplify the compressed audio in a detrimental way
-
I enjoy the way this amplifier looks as well, the glowing tubes are very pleasing to the eye
-
The best way to describe this amp is it's like going into the room where the musicians are playing only with better acoustics

Reviews around headphone (3.61 of 5)
-
This is a good headphone amp, especially for the money.
-
I was not happy with this product, it did not get my headphones loud enough for me to hear clearly and also the input jack was broken on the inside cause my male plug cable could not push in all the way (had to open to fix it)
-
Of course, I'm listening on good headphones which makes a difference, but this little amp made them shine
-
To top it off, when any of the connections gets too loose(frequently happens) it causes my headphones to spasm at max power and destroy my ears
-
if you do not have good headphones with good drivers you WILL blow them

Reviews around product (3.39 of 5)
-
This product stopped working after only using it for a couple of months
-
A very misleading product that caused me to waste $150 on various E180F/6688 tubes before I realized they did absolutely nothing
-
Overall It's a very nice product and I would buy it again.

-
An almost-inaudible hissing (17Khz+) can ruin the product for many, this may be due to the quality of the tubes, but I don't have any to swap with the ones that came stock

Reviews around unit (3.36 of 5)
-
The unit looks exactly like the photos, with an attractive bronze trim, and I admit I enjoy the blue light under the tubes quite more than an adult man should
-
I can't talk about every unit sold, but I can definitely say that the unit I received was awesome.
-
Also, this unit is horribly susceptible to cell phone RFI (radio frequency interference), so when it buzzes on my desk I can hear it in the electronics
-
These issues might just be because this unit was damaged in transit or broken, I don't know
-
Power supply was dead on arrival and the unit had a loud hum when powered by an equivalent power supply.

Reviews around tube (3.31 of 5)
-
The only two reasons I didn't give this Five Stars is because 1) the stock Chinese tubes this comes with are pretty terrible and 2) I had to buy a 3.5mm headphone extender adapter b/
-
Didn't follow the recommendations to replace with more expensive tubes
-
Some lesser testers have "proven" that the tubes function as an amp by simply noting the power-up delay as the tubes heat up.
-
The original tubes are good but if you get the original Valvo it's better
-
The stock tubes sound terrible, but any other tubes won't help because it is not working as an amp

Reviews around noise (1.33 of 5)
-
The other reviews are spot on with this item, it picks up cellular traffic frequently and gives you a static beeping noise
-
Mine makes this weird noise, replacing the ac adapter might work though.
-
They work great because they block out unwanted background noise and sometimes that ability overrules all other requirements
-
Mine makes this weird noise, replacing the ac adapter might work though.
-
The push button in back isn't as convenient especially since it makes a loud noise when the power is switched on or off while the volume is still turned up.

Reviews around pop (1.00 of 5)
-
I haven't even noticed the loud pop that is supposed to happen when you turn it on with your phones plugged in.
-
But the pops and clicks that are added to the audio are extremely frustrating!
-
To avoid unwanted pops and thermal noise, suggest let the tubes warm up for a minute or two before jack-in and jack-out before turning the unit off.
-
I had my headphones on my head and turned the device on, and heard a loud pop like noise
