Just bought an Edifier H280 IEM to pair with my Nexus 7 so here's a mini review after 12hrs burn in
Really really suprised at the sound quality for such a price (RM39)
Sounds quite close to SoundMagic's PL-21.
- Bass is quite prominent in quantity n quality, just that it does not slam like 21's.
- Low punch bass notes, mid bass notes like those of a bass guitar (120 - 180hz) are not prominent.
- Also slightly smaller sound and crispier higher end, better seperation and sounds clean/smooth.
- PL-21 sounds 'bigger/full' but slightly darker and slightly less seperation, sounds a little harsh to me too.
- Still quite some distance to a Hippo White which sounds quite large and punchier with good seperation, but a White costs RM100+.
- Easily surpass EP-630/660 (Creative >RM80) and most Sonic Gear IEMs. Razer M100 too (>RM100).
- Can bring out some small details and good instrument layering. However still has a slightly 'small' but smooth sound
- Sounds best at low to moderate high volume. Congested at high and very high volume.
- Sounds like a slightly 'cold' Edifier C3 if u ask me.
- Personal opinion, sound signature is better than some Ultimate Ears (UE), they sound really cold, congested and loud. In my opinion sounding big and full is one thing, sounding just loud and forward is another thing which is kinda fatiguing/annoying. But this is my taste and will vary with many.
For RM40, i dont think there is anything better for super-budget IEMs... Maybe they should start taking down those SG iems from the shelves...
Songs tested with, these songs have quite good mastering imo:
ATB ft. Melissa Loretta - If It's Love
Enigma - Principle of Lust (full/reprise/11min version)
Madonna - Die Another Day
Within Temptation - Faster
TJR - Ode To Oi
Norah Jones - Those Sweet Words
Norah Jones - Turn Me On
Olivia Ong - I Believe
S Club 7 - Say Goodbye
Nexus 7, Realtek Chipset.
Asus K40, VIA VT1708 Chipset.
Macbook 07' Sigmatel Chipset.
jus normal stuff

Finally I saw a H280 user...
HI^^
and happy new year everyone~
i have few question to ask~
i wan to bought a 2.0 speaker to my room~
i use laptop(which have dolby advanced audio v2)
i budget around RM450~
and i have review about edifier r2600~
i will buy a pair speaker after new year~
i am always listening music~
and i also like to watch movie(like:terminator,the dark night rise,the avanger)~
have everyone using this model?
can anyone give me some advice?
R2600 is a good speaker, worth to get one. and loud enough for most usage. But I suggest you can remain your sound card extra features off (dolby, surround effect, etc) to avoid colouring your sources.
