Bonus impressions TBC.

 
The link below is my first impression for the Mk1 (version 1):
http://www.head-fi.org/t/631599/hippo-biscuit-music-player-review
 
The second version (mk2), which comes in more color (Red and Blue are now available, I chose blue), the button changed to a softer gel, and the time to switch on/off the player has significantly reduced.
 
Sound quality wise is still the same for Mk2. It's ideal for hifi recordings (clean music reproduction) and not so ideal for casual (fun, with certain coloring) use due to the constrain of features available in conventional players, such as the features of bass boosting, EQ, and etc.
 
To me, in my region, a sub $100 player is limited to several choice only. Commonly casual users go for iPod (with a little more topup), Sony players (more features, but to me, the interior amplifier is not powerful enough), or Sansa series (more audiophiles choose them because of the Rockbox feature) Therefore, Hippo Biscuit fills the void for the "Budget" Audiophile market segment.

I've owned E7 before, and had a Centrance DacPort LX. Well, E17 fits the bill to be the value buy (Over here Audio gears are expensive).
 
Sound Quality: Nothing impressive. Just plainly neutral with slightly rolled off treble. Not as energetic as the previous Dacport LX. Doesn't like to mess with the bass/treble boost functions. As an amp, it's quite powerful. Can drive my T70 (250 Ohm) with ease (my comfortable listening volume is at 45, minimal gain).
 
Built: Tough as tank, solid. Love the LED, looks classy. Quite bulky.
 
Features: Lots of features available. Bass/Treble Boost, channel configuration (left right +/- gain), is portable with built-in battery inside. Lots of optional connectivity (coax, usb, aux-in) and also DAC part supports up to 24/96 on USB (well, even the screen will show the playing song's bitrate info).
 
Value: Considered one of the cheaper and versatile DAC/Amp combo. Great for on-the-go audiophiles.

After struggling to find an ideal universal flagship IEM, I finally chose Shure SE535SE.
 
Reason:
Cheaper deal I got over here, compared to W4R which will be around USD$100 more.
A strange affinity towards Shure brand.
Beautifully painted body and beautiful packaging.
 
Honestly, I'm not really particular in auditioning the IEM before purchase. Reason is because it takes time to appreciate or get used to the new sound signature. And I wanted a flagship IEM so that I can stop (temporarily) searching for a better IEM while learning what BA drivers can do. Probably later I'll go for W4R or EX1000, where the latter would be more intriguing.
 
I'm a dynamic guy. So BA is kinda fresh to me. What this IEM lacks compared to dynamic ones is the bass punch. It's decent, but not as airy and powerful compared to dynamics. But the thing that impressed me right out of the box is the sense of depth in soundstage. Boy I was really enjoying the chanting and whistling behind the back of the songs in Hell Freezes Over.
 
Frankly speaking, this thing is not 50% much better than any IEM 50% cheaper than it. Value wise, it's better to go for cheaper alternatives, like SE425, or what I've tried myself: GR07, EPH-100, and those ultra value buy dynamic IEMs. However, there'll be time when I felt discontented with the lack of something in the sound by those IEM, and wanting more. Thus here I am, listening to the SE535SE.
 
This IEM is highly dependent on the source you feed it. The better the source, the more it will be able to perform. In short, Source>Headphones.
 
Edit (11/23/12): After a few month using it, I noticed that:
1. Bass: Bass is deep, but not having much impact. While remaining airy, the bass don't punch the ears. Even on pop songs which normally have powerful bass, 535LTD isn't really portraying any much punches.
2. Details: Arguably one of the better IEM with good details However, due to the nature of the FR (rolled off treble), much micro details isn't really in-yo-face. Well, I guess 535LTD is more towards fluidity of the presentation rather than a microscope analyzing all the details (or defects) of the song. It's very enjoyable, yet not for those who demands excellent micros.
3. This thing isn't really isolating 100% of the sound. It blocks out most of the little annoyance, but not moving trains or roaring thunders. I'm not sure if it's due to my use of the Olives, but 535 to me is brest used with the Olives.
 
Thanks for reading. And enjoy your music :b

Do I like this IEM? Yeah.
Do I love them? Nope.
Why?
 
PFE is a single BA IEM, which possess, IMO, the stereotype signature of BAs in the market. The sound signature is about clarity, balanced, and non-fatiguing. While the headstage is quite narrow, the bass is anemic. It's more for casual listening, and well, I'd praise its comfort design. Once hook up onto your ears, you can be sure to forget about it (and sometimes the music too, because it's so inoffensive and to me, unimpressive).
 
So, do you want to buy this IEM?
If you want something engaging, go elsewhere. See TF10 or others which really shine in a department.
If you champion comfort more than engaging sound signature, this may be yours to ponder.

It was a historic IEM for me, although it does mark itself as the first "better" iem that I've ever purchased since the $25 Sony In-ears. I can't comment anything now, because it has been such a long time since I heard it.
 
Just from what I've remembered, an un-amped SE102 has little mid bass hump, is generally light in lows, and neutral vocals. That's for what I can remember clearly.

Tight competitor of GR07, this IEM isn't a replacement for GR07, but rather, a complimentary IEM.
 
How does it sound? Fun, thick, and musical. Not your best analytical sounding IEM, while it does bring out details nevertheless.
 
To me, it's a great buy, because I don't need anymore accurate sounding phones, but rather something fun and colored to my personal preference. Mainly use it on portables and listening to vocals, rocks, and oldies.

Since there isn't any review on this can (T70-250ohm), I would like to share some user experience over here.

 

 

Audio rig: Laptop Foobar 2000-Wasapi output -> Centrance Dacport LX -> Govibe Peak Amp -> T70.
Mostly listen to: Vocals (Female over 70%), Tracks from 70s, 80s, 90s, A few rocks (Bon Jovi, Aerosmith, Queen, etc.), minor pop.
Self-rating audiophile level: 3/10 in terms of experience.
Past experience: Shure SRH840, Futuresonic Atrios M5 (MG7), Radius TWF11r, 
 
Build: 4/5 Tough, German-trademark build. It looks fragile to me (ironically, LOL), but when I hold it, I can feel that it could withstand daily use (not abuse). One sided cable input is unfortunately a ban for some audiophiles.
Accessories: 3/5 A leather headphone bag, 6.3 inch adapter, and... no replacement pad, which I highly appreciate in Shure SRH840 for durability.
Isolation: 2/5 Mediocre at best, can mildly hear the sound of the wind hitting on the exterior of the headphone driver.
Comfort: 4/5 Comfortable padding, but will get hot after around 1 hour of use. The headband has soft cushion too. Clamping force isn't as strong as SRH840, just right for me.
Aesthetic: 4/5 Looks nice to me, minimalism design. 
 
Sound:
Low: 8/10 Frankly speaking, what is lack for me is the more powerful midbass punch of beats. That's all. Other than that, everything is just perfectly in place. Tight, accurate bass reproduction is what I like. And normally, this headphone doesn't unleash its bass potential unless the music asks for it. I can go through several songs without feeling anything until a nicely tuned bassy songs will suddenly crack my head. It comes by surprise, as I didn't expect the punch to be so sudden. One thing I like on T70 is that the lows do not overshadow the mids and highs, which I highly appreciate as I render bass as a supplementary rather than the main dish of a song. Drums feel rather real, as the vibration can be clearly "seen" and not just felt.
 
Mid: 9/10 Overall neutral, but I cannot guarantee it sounds neutral to you. LOL. I'm just owning only a few audio rigs, therefore I cannot confirm that it is entirely neutral on the mids because it sounds smooth to me! Me and my friends used to call it, poisoning. I felt at home when listening to the vocals, as I can clearly hear the singers breathe, clear their throats, or even cough.
 
High: 9/10 Treble may be piercing before burn in, as some notes are quite offensive to my ears. Unlike Shure's rolling off-ed highs, T70 just let the frequency goes as far as it can extend. Therefore, it feels more "real", in a sense that I would not miss a sound due to suppression of the highs. 
 
Presentation: 8/10 The soundstage may not be as wide as the open cans, but it is definitely wider than most closed cans I have tried in the store. Depth is also present, as I can distinguish the singer standing in front of the drums. Instruments can go very far apart if the track requires, which isn't found on my SRH840. The overall sound sig is more forward, and not entirely closed as I can feel a sense of spacing between all the instruments. Thanks to the "HD" Tesla driver, I can feel that I "see" music, like where all the instruments are placed. There are abundant micro details which i never thought existed when I re-listen my past tracks. When I close my eyes, I can "see" the sound coming in and out from all direction, like the plane flying in a distance from left to right, cars zooming past in front of me and quickly drift far away, and etc. It is a wonderful experience!
 
Thanks for reading. I hope that I can have some comments on this review as I am still a learning rookie in this audiophile world.
 
Edit 11.23.12:
It's been months since I've last spent on this headphones. I'll re-rate it here:
Bass: I understand that the lack of punch is due to the use of micro-velour padding, which absorbs much of the bass impact in exchange for more comfort. It's still clear, well, I've never experienced a bloated bass on T70, maybe... poor recording perhaps, or my songs are yet to be demanding.
Treble: This can might grow treble hot sometimes. The piercing (especially on pianos) is unbearable. I'm not sure if this is how Beyer's sound engineers perceive "realistic" as, but that's one too sharp to my ears.

This is a very very early review (just a few days from my purchase).
Reason I bought this can is to invest in some home entertainment hub for myself. Initially choosing M50,
but it's out of stock when I tried the demo set over and over and was about to make the purchase. sad.
 
Then I changed my mind, go for SRH840. Turned out to be not bad. Compared to M50, this can is seriously discolored (what I mean was, the bass is flat, the mid is clear, and the high is just flat, nothing outstanding). Although i still think i would like the more "fun" M50, which is quite bassy and colored (monitoring? I don't know, more towards entertaining). But SRH840 gives me a great chill on what I always wanted - DETAIL. This can is a detail monster.
 
I'm not even qualified to be called audiophile. Just someone who enjoys occasional music. But I love what I heard. The road not taken was M50, maybe next time (after 5 or 10 years later), I'll find something fun (Maybe too late? Haha.)

First time writing a review:
 
Bought it because I love good vocal from the song (especially enjoy oldies), not a bass-lover, not so much. Initially wanted Shure SE215, but at the store, the TWF 11 sounds better in vocal richness (No idea how long they burn in the earphones).
 
Initial thoughts before 100 hours burn in : It sucks. Blurred vocal, instruments. Bass overwhelmed everything.
 
After 100 hours burn in: Splendid vocal heard, vocal centralized in the middle, leaving the instruments on both left and right sides of the ears. I love details, and TWF11 has given me much music details, like the musical instruments..err.. tinging?
 
Bad: Poor fit to my ear, keep on twisting the earbud inside. Long hour of use often results in discomfort.
 
That's all. Thanks.
