You'll be very happy !!! I use mine to listen 6 - 8 hrs a day, battery life is awesome. One thing it took me a little while to clear up, is the how to get to the High Gain Mode, you do this by : After powering up, toggle up or down to select your base mode, then hold the toggle button in for several secconds, it will turn to blue, if you toggle up, that raises your basic volume, to get to High Gain Mode, push the button up, and hold it up for 6 - 8 secconds, and it will turn to a pink/purple color, you are now in the High Gain Mode, CAUTION though, turn your computer / phone or whatever your source is, volume WAY down first, because there is a SIGNIFICANT jump in volume, trust me, the difference between the highest normal blue volume, and the volume that will come out of High Gain, once it switches over is HUGE......Good Luck, I know you'll love it !!! I had the Fiio 11 amp before, and the digizoid ZO is just SO SO SO much clearer, in my oppinion, it basically doubles the dollar value of the headphone you are listening to ie if you have a $ 200 headphone, it makes it sound like a $ 400 dollar one.... I don't know what type of music you listen to, but I love Techno music, even if you don't....this is a track that I use as a " measuring yardstick " of a headphones bass capability. At 3:15 and 6:15 mins, the bass line just punches harder than any other I've ever heard, so even if you don't " like " this piece....listen to it, to use it as a tool, to find out just how hard your headphone can punch a bass line.

Also, if Electronica with hard punching bass, is something you DO like, then I would recomend trying the SOL Tracks HD - on sale now at Amazon for $ 95
http://http://www.amazon.com/gp/product/B005OLOIUI/ref=pe_58260_30255860_email_1p_1_ti the company makes more expensive headphones, but this is the one to get if you like bass, some reviewers here have given it stuffy reviews, granted it may not be your cup tea if your trying to discern weather a violin is a true stratovarious or not, but for bass punch, nothing beats it....I accidentely stumbled on this headphone. My M50's broke, so I decided, I am going to save up a bunch of money, and " audition " some of the best expensive headphones out there. I saw this headphone, and purchased it, casually, just with the intent of a very temporary stand in, until I saved up the money for a top of the line headphone, Eventually I did, I purchased a Grado SR225I, Audio Technica ATHESW9A, Beyerdynamic DT-1350 as possible portables, and also as " Home " based models, the Ultrasone Pro 900s - the well renowned so called " King of Bass " for Bass heads, the V-Moda 100, and also the HI-FIMAN HE 400s and Bose QC 15, the HI-FIMAN EF2A tube amp, to really give all of these headphones a fair shake, with intent of purchasing one of the portables, and probably one or two of the" Home " models.....
.Well, I swear in a million years, I never thought it would turn out this way, but I " burned " them all in with 150 hrs of Pink Noise each, also upgraded the tubes on the EF2A amp, and set myself to giving each of them a fair and thorough " shake down " and no matter how I stacked it, blind tests, different music styles, adjusting the headbands, with amp, without amp, with Digizoid Zo amp, without, connecting the amps in different assorted " chains "......No matter how I tried all possible combinations, I just couldn't believe it, but I kept reaching the same almost illogical conclusion - I liked the SOL Republic Tracks HD BEST ...The Ultrasone 900 reached a lower bass level, but sounded like a large bass drum with a blanket in it. The Grado SR225I would probably be my second choice, it was very FAST, but lacked bass PUNCH....I think that's probably what impresses me most about this headphone - it is very FAST, and nothing even came close to the clear hard hitting PUNCH PUNCH FAST - HARD HARD HARD !!!! of this headphone. Believe me you, I was all set to spend big time cash on a headphone, and amp, had it all alotted in the budget, wanted to spend it.....but in the end, I couldn't believe it, but I packed all of these headphones up and the EF2A amp, and sent them back to Amazon.....
I have found my ideal with the Digizoid ZO amp, and the SOL Tracks HD headphone. Also as an aside, if you listen to a lot of streaming music, I stream
http://http://www.di.fm/ epic trance channel, through music player
http://http://www.winamp.com/ select their options..equalizers..pree-loaded, SKA...select visualization...( kinda corny - but I like ). It took me a LONG time and a lot of research to get here....Try it, all you have to loose is return postage to Amazon if you don't like the headphones, but for $ 95 - why risk loosing out on what you could actually be experiencing.....don't listen to the stodgy old violin/ cello " experts "opinions... I give you MY word, hooked up with the ZO bass turned up, running a hard bass line, Nothing will Punch like this set up !!!!
My Two Cents !!!
