Summary: After trying player after player to include the 602 I have come to realize this was the perfect match for me.
I too use the UM3X, but also Grado 325i's, K702's (300ohm) and Senn IE6's. This player just wants to push them all. Aside from the 35 presets The EQ settings are ENDLESS!
Pros: Storage, a palette of EQ settings, ease of navigation
Summary: Needed a good player for my FLAC and APE files (which my iPod could not do).
Bought this player on the various internet recommendations although its ridiculous expensive in Europe (239 Euro for 16G version).
It's a very good audio player in a nice looking package.
Pros: Compact, lightweigth, very good sound (for portable)
Cons: Feeble USB / mm card cover, software stability issues at low battery
Summary: Fairly new to mp3 players, tried the Ipod Nano 6th Gen. Never would shuffle worth a damn.
Same 150 songs over and over. Researched this J3 here and purchased it. Followed ALL instructions as to installing the newest `firmware' using my Mac.
Summary: My best Pmp so far.
I have tried sony's, sans'a, and cowon j3 is the best so far.
Unfortunately I lost it, and now it is discontinued so I have been trying to replace it, I bought a Sony Walkman A 865 which was sent back due to the poor battery and poor Eq, after that I bought a Cowon Z2 basically...
Pros: Battery Life, sound quality, audio formats, simple to use
Cons: Does not support many videos formats, blue-tooth not that good.
Summary: The short and simple of it is this is the best DAP for the price I have owned. I have used all the main stream players, (IPods, Zune, Creative Zen Player, etc) and I will never go back. Besides the great audio quality, the battery life is unparalleled.
Pros: Extreme Battery Life, BBE & Jet Audio Effects, EQ, Lightweight, Superior Audio Quality, Supports Most Formats
Cons: Screen resolution, Navigation has a learning curve
Summary: For most people, Cowon J3 is pretty much the ultimate 'non-audiophile' music player for its sound quality, battery life, and expandable storage (I've heard of 64gb micro sd cards working on it, I haven't tried myself yet).
Pros: Sound quality, expandable storage, zero hissing, BBE, battery life
Cons: Proprietary cable, difficult to create playlist, still pricey online after many years.
Summary: COWON J3 16GIG V.S. I TOUGH 2nd gen 8GIG*for sale and jail breakable*
Well where to begin.... I got this to replace my Itouch*that it for sale* due to the fact that the headphone jack is broken an easy fix I have guides for but I was looking for any excuse to get rid of the thing.
Pros: GREAD SOUND!!!, easy interface, not apple, almost ALL music format support, customizeabal, small, lightweight, GREAT screen touch and visual wise.
Cons: A little too flimsy feeling, The interface takes getting used to coming from an Itouch.
Summary: Background: When I lost my S9, I had to find a replacement. I began to look for options, noting the Cowon J3, Nationite S:flo2, and Hifiman HM-601 as possible options. Then I discounted the Hifiman for the sake of portability.
Pros: Sound Quality, BBE EQ, Battery Life, Durability, Buttons, Usability, Drag&Drop, MicroSD Slot, Screen, Powerful and Clean HO (works well as a LO)
