At first, I want to say great thanks to FiiO who allowed me to join world tour of X1 2nd gen. This review is written as a part of its world review tour. I have to add that, I have't got any compensation from FiiO.

Introduciton:

Now I owe FiiO X3 1st gen and X3 2nd gen, so I was very looking forward to try bland-new desigin DAP, X1 2nd. Its new design is very cool and may be satisfied from non geeks I thought. Audio quality is not bad, but it was lower than I expected.

Audio Quality:

 
FiiO X1 2nd has improved its chips from X1 1st. It is true I thought, its sound resoltion has improved ordinally X1 and its output power is higher than  one. But when I compared X1 2nd to other DAPs cheaper ones such as Seiun Player or Xduoo X3, I couldn't feel larger improvemnt. Unfortunatelly, this makes me bit disapointed.

Output:

To review this X1 2nd I used it everyday in a week with Etymotic Reserch ER-4P and KZ IE80.X1 2nd's output power was good enought to sound these earphones and there seemd no disconent. I have to point, this DAP is not designed to sound headphones such as AKG K702 or other ones, but for earphones great to use.

Sound Quality:

As for its sound quality, the balance of its quality is better. But thought the bass sounds is worth than other DAPs including FiiO X3 2nd. Sound resolution is clear but it did not make me satisfied enough. Some of  reverb is difficult to hear from X1 2nd althoght I can hear from X3 2nd.
The worst thing of X1 2nd is noise. I take it everywhere everytime, X1 2nd always catch noise from cellphone.The noise was larger than we expected, to avoid the noise, I had to put my cellphone my bag or other side pocket. The problem of noise from cellphone is pointed from X1 1st, so I'm very disapointed why it is not solved yet.

Design:

 
FiiO X1 2nd was changed its design dramatically from FiiO's other DAPs such as X5, X5 2nd, X3 2nd. Integrated display and touch panel wheel is very cool and X1 2nd's rounded body is very well to catch by hand. We Japanese geeks sometimes call FiiO's ordinally DAP style as "ガスコンロ=Gas stove" but balndnew style will be never calld as that.

UI and response:

FiiO X1 2nd's UI is almost same as its ordinally ones. I favorited FiiO's UI style, so I can say it as duly evolution.But as for response, balnd-new wheel response is not good than I thought. When I select songs, I always use additional keys to select that.
And I have to add for responses, when I selected play, pause, skip and so on. The deleay is longer than other DAPs including X3 2nd. It sometimes made me annoyed. I updated to FW 1.41, it is bit improved, but still worth. Hopes to improve that.

Battery life:

I used X1 2nd very long time everyday, but battery life was very well enough, when I use it 5-6hors in a day,there still too much life.

Conclusion

I've used X1 2nd for a week and surprised its cool design, unfortunatally there still have some problems when I use that. Too slow response, noise from cellphone and so on. But at all, I can say X1 2nd as a one of the most great cheap DAP around 100USD. I can suggest my friends who is non geeks on audio as a best DAP for daily listening. I'm looking forward to meet more great DAPs from FiiO.

At first, I'm very thankful to FiiO for giving chance to use and review this great portable music player.
I'm owner of the FiiO X3 1st, E3, E7 and E9, so I know how FiiO made great DAPs and portable amps.
This X3 2nd gen is one of the greatest DAP which FiiO made than ever, I thought.FiiO always give us variety of choice of hi-grade DAPs and portable amps at an affordable price.
 
There's no doubt that X3 2nd gen give us great experience with great cost performance.

THE REVIEW

 
Package

 
I know the package of E3, E7, E9 and X3 1st, and FiiO products' package designs are becoming more cooler and cooler.
But I have to say that it is NOT easy to open retail box and other boxes.
 
For accessorise, there includs follwing things,
・micro USB cable
・A digital out to coax cable(4pin plug)
・3 type of stickers.
・Warrenty card
・Quick start guide
・spare screen protecters

Comparing to X3 1st and X5

 

 

 
I wrote I own X3 1st, so I have to compare and tell you how X3 improved from 1st gen to 2nd gen.
You know X3 1st's sound is warm and musically with thick Bass and cleaar High (in Japanese we say sound like this for "Don-Shari, ドンシャリ")
Comparing to X3 1st, X3 2nd's sound is cleary sound, monitor like sound I think.BUT more musically than X5.
X3 2nd's sound inclination lie between X5 and X3 1st.
I forgot to write, sound resolution improved from X3 1st, nealy X5.(But X5 is still better than X3 2nd)

Sound Quality(phoneout):

 
hmm, I wrote X3 2nd improved its sound resolution from X3 1st.
Then, I'll write X3 2nd's own sound quality.
These reviews based on the set of X3 2nd and Etymotic Reserch ER-4PT.
 
High:
X3 2nd's high sound area is very clear, as X3 1st and other FiiO products.
Its' female vocal quality is very well, brought up free of all care.
 
Bass:
X3 2nd's bass is smarter than X3 1st, it's tight, solid, but I did't feel unsatisfying.
I can hear enough bass line, but this bass line is not superfluous.
 
Overall and comparing to other DAPs:
Right, X3 2nd's sound is clear and bass line is very tight.
For sound resolution and soundstage, X3 2nd improved from X3 1st.
 

 
At last, I'm very proud to became the member of reviewer.
Actually, I bought X3 2nd and it is already arrived and I use the unit everyday.
Thank you FiiO!Giving us great chance and great unit!
