Brilliant device

The most thoughtful thing about the Ultrasone Naos is that it comes with all cables for pretty much out-of-box plug-and-play operations and can connect to pretty much any mobile device. Its so convenient. I am using it with my Note 8, iPhone X, iPad and Mac. It works pretty well with all of them. And it is so compact.

As for the sound, it is crispy sounding. The soundstage is great, vocals crisp and clear, instrument separation is good. You won’t believe this sound coming out of this small a package. Don’t know why it’s out of stock for so long.

Little Beast

what can i say about this tiny beast..? i am red dragonfly user for a long time. its simply overtook dragonfly in every aspects.. My S9+ is rocking with this tiny beast. Thank you guys for the quick delivery

Great Value

Ultrasone Naos is a an excellent DAC/Amp combo for the price offered by headphone zone. Its extremely portable and comes with a host of adaptors. Now what makes this special is the sound signature. It offers a distinctive sound where mids are moist and intimate, with great resolution, instrument separation and clarity. It has more than enough power to drive my 300 ohm sennheiser HD650 . I felt that this makes HD650 more punchy and alive, considering that HD650 has a dark or laid back sound signature. However on the flipside, this might make bright headphones more bright, and so may not pair well with bright headphones. Depending on your sound preference you might like this very much (considering its price-value ratio), or alternately, if you are in a quest for a really warm and full bodied sound or want a dac/amp for a bright headphone, then its worth to audition this once before buying. Thanks to headphone zone for making this accessible to Indian audiophiles.

Great Sound in an ultra-compact package

The best thing about the Ultrasone Naos is that it comes with a bunch of cables and can connect to pretty much any mobile device. Its so convenient. No more scouting around for these connectors. I am using it with my pixel 2 xl, galaxy s8 plus, iPad and Mac. It works pretty well with all of them. And it is so compact that I am afraid I might lose it.

As for the sound, it is warm sounding. The first thing I noticed when I used it with my ultrasone performance 840 was that the bass got tighter and more pronounced. The soundstage was better, vocals crisp and clear, instrument separation is good. I am glad I got this one.

Good sound quality

In the price value u will get a good sound quality.
Initial my review on this one is not good thats bcoz i didnt recognised the listening experience of this product. Now i completely understood listening experience. U will get a good listening experience from this dac. Loved it.


Am using rha s500u.
And am using zte nubia n1 mobile.
Actually the headphone jack of my mobile is prerty good. And i wanted some more quality. When i ordered ultrasone naos my thought's are high. But when i recived the dac i observes only little differ in a way of good sound quality which the naos did but not so much as compare with my mobile headphone jack. And i felt low bcoz my expectations are too high.
