The RE2 earphones are made for sound enthusiasts and audiophiles. They look like a regular in-ear, but the sound is anything but regular.

The HiFiMan RE-400s offer audiophile-pleasing sound quality for a very reasonable price -- just $99. All types of headphones, even very good ones, have different trade-offs, but the RE-400s excel in clarity, beautifully balanced bass-midrange-treble, and noise isolation, and they're quite comfortable.

HiFiMAN’s ES100 is a solid entry into the earbud market. Whilst it is not perfect, it does have many merits, particularly at its price point. Those seeking a fairly balanced, natural and detailed sound would do well to consider the ES100.

RE1 is a perfect example of a very special earphone that caters only to devoted audiophiles that have need for great sound quality. …The amazing thing about the Head-Direct RE1s is that they scale so well when amping them. The better the amp, the better the detail, speed, extension.

…super-easy to drive. Even the feeblest phones and MP3 players will rock your world with a set of RE300s.

RE800 uses all new Topology Diaphragms, referring to the diaphragm with a special Nano particle coating applied to its surface. The distribution of the coating has distinct geometric patterns. By varying the surface pattern, compound used, the thickness or geometric pattern sound wave formation can be manipulated to achieve the desired audio effect and control. The idea behind the new Topology Diaphragm was inspired by Dr Fang Bian's Ph.D thesis that "different Nano materials have differing structures and each of those materials have its own properties". Therefore, by carefully controlling the diaphragm surface structure you can yield different results in acoustic performance to a degree previously unobtainable.

Hifiman's uber-comfortable RE-600 offers superb transparency and accurate tonal balance.

RE252 really redefines what I would call as a 'balance' sounding IEM in its own terms as I can hardly say if there is any major flaw in its sound. Perfect it might not be, I think RE252 does earn to be crowned the new flagship of the RE series.

Over the course of the last month when I have been listening to the RE0 units heavily, I have developed a deep appreciation for Head-Direct's engineering team. They really made a quality product. … You would be hard pressed to find a set under $200 that sound better as well.

The exceptional clarity, detail, smoothness and natural presentation offered by the RE-ZEROs is well worth the asking price and these IEMs, like the RE0s, perform well above their price point.

HiFiMAN’s RE-262 is an excellent mid-priced earphone with a number of unexpected and unconventional design elements. … you’ll find its strengths center on it rich, vibrant, luscious sound, which is always engaging and easy to enjoy for long-term listening sessions. Sound quality, pure and simple, is what makes this little HiFiMAN earphone shine brightly, and at a very reasonable price.

This was probably best spent usd 200 on any headphones Ive bought so far! Sound is incredible after 90+ hours very detailed neutral with just right amount of bass. It is not true that these have no bass at all! Thanks for these HiFiMan you are now my Nr.1 brand for headphones!

マルチBAとは音の個性も違うので一味違うカスタムIEMを求めている人、ダイナミックの音でカスタムがほしい人、重厚なベースを望む人などにお勧めです。
Recommended to those who are looking for a custom IEM that stands out from the others, with a sound of dynamic and a heavy base...
