What customers say about "Key Specs"
HiFiMAN HM700 32G Portable Player plus RE400 In-Ear Monitors/IEMs
  • The fact that they actually at this price point, give you so much is simply astounding. It sounds... phenomenal and I have heard a lot of players.
  • The player is very nice, 32 gigs of storage comes in real handy and no need to buy anything to get it.
  • Display doesn't have the highest resolution, but we are not talking about video player or smarphone, and I found it perfectly adequate for song artwork view.
  • This player has great build quality and battery life. The sound is very neutral on this player. Not "warm" but not harsh either, mostly transparent.
  • It's extremely dark to use in direct bright sunlight and actually make use of the display of figure settings or otherwise.
Fiio X3-II High Resolution Music Player (Black)
  • I also don't like the way it displays my files.
  • I love the way it shows me my screen art - as I've taken the time to tag and put in screen art for nearly all of my collection .
  • The font size is very small and hard to read. I ended up picking the theme with the best contrast so I could read the menus. Still, with less than good eyesight I can barely read the display.
  • The UI could be a bit more convenient and the display is not as great.
  • The display is fine indoors, but a little hard to read outdoors.
  • The screen isn't bright enough. And its small, so its almost impossible for me to read in daylight, forget while driving

What customers say about "Size & Weight"
HiFiMAN HM700 32G Portable Player plus RE400 In-Ear Monitors/IEMs
  • A 32gb, 15 or so hour playback time, easy to use, compact and well built.
  • With a small footprint fitting in a palm of your hand, it weights only 3 oz with a compact dimensions of 105mm x 49mm x 12mm.
  • It's super compact and durable (just google YT video of HM-700 falling test - it's insane!!!).
  • This is a great product. Music coming from this player and the in ear monitors are clear and impactful for something this small.
  • I love this player, plays all formats, is well-built, sounds amazing and is compact.
Fiio X3-II High Resolution Music Player (Black)
  • Small and compact for his pocket w/out dropping out or loosing it either.
  • It is very compact, but the sound quality is excellent.
  • All aluminum case, good size in the hand, screen is easy to read and back-lit.
  • The size of the unit is very nice for dropping in your pocket.
  • Minuses are a less than ideal interface and it is quite heavy for it's small size.

What customers say about "Features"
HiFiMAN HM700 32G Portable Player plus RE400 In-Ear Monitors/IEMs
  • I decided on the HM-700 largely because there are a powerful amp section and supported FLAC.
  • Balanced headphone output equipped DAP with a set of HE-400B balanced i.e.m.'s (in ear monitor's (you may know these as earbuds or in ear phones). Oh, and all for the price of an iPod Classic.
  • The RE400 sounds quite surprisingly, and refreshingly, good out of any "good" or "great" source you plug them into.
  • String bass, piano and drums (think jazz trio), I set the equalizer to emphasize the bass....and regardless of the style of music, I hear a clean sound, showing the full range.
  • That being said, the combo is fantastic. The bass goes deep and is extremely textured, but is neither emphasized, nor recessed. It's just perfectly balanced.
Fiio X3-II High Resolution Music Player (Black)
  • You can have as much memory cards as you want, which makes your storage space virtually infinite.
  • You can use this as a beautiful sounding Hi res audio player with natural slightly warm neutral sound as well as a DAC to listen to your music on you computer with much better quality.
  • However, in addition to purchasing the MP3 player you have to purchase a memory card and a device to format the memory card.
  • User interface is horrible. Selecting genre, artist or album is very complicated.
  • Making internal playlists is borderline impossible, and importing playlists is very complicated.
  • Excellent player, a little tricky getting the software figured out, but when you do it is well worth it.

Fiio X3-II

What customers say about "Power"
HiFiMAN HM700 32G Portable Player plus RE400 In-Ear Monitors/IEMs
  • Great sound, especially with 400B headphones; Battery lasts for 6-8h when playing flac files (not bad); Bit rough UI. Really great player for the money.
  • HM-700 packs a very impressive spec for a portable DAP with 32GB of on-board flash, battery life of 15 hours, and support for various music formats.
  • You get 32GB of storage and 15hr of extended battery life, not to mention a universal micro-usb connection.
  • A major issue that I have with the HM-700 is the expected battery life. My experience falls far short of the advertised 16 hour battery life. I generally only see 5 to 6 hours of operation before needing a recharge.
  • The battery life doesn't last long, but the device has alot of memory.
Fiio X3-II High Resolution Music Player (Black)
  • Battery life seems really good.
  • Battery life is acceptable.
  • Battery life is fine, more than four hours of continuous use.
  • I think that at this price point along with the size of this unit that the battery oughta' last longer.
  • With mediocre battery life. I'd say 6-8 hours that degrades to 6 hours after wearing it in for a few months.
