REVIEW: Head-Direct RE 1 IEM's

We all start our journey into the word of digital audio with a basic player and stock earphones. Some feel the urge to upgrade to better stuff, some don't. I am one of those who's never satisfied when it comes to quality sound because I just love my music, it's more than a hobby or pastime for me.

When I got the Altec Lansing MX5021 speakers modded, I started to dislike the Creative EP-630 which I used to love earlier and I wanted a pair of earphones which sounded much more refined like my speakers, so after taking a few suggestions from Faheem, and other members I finally upgraded to the Head-Direct RE2.It is one of the best IEMs I've had till date, and when paired with the Fiio E5 it's just unbeatable even for double its price!

Later when I got the Cowon D2+ and started looking for an upgrade to RE-2 as well .I was ready to spend up to $200 provided I get something worth the moolah. After a research of about 3 months and speaking to few audiophiles, reviewers for many IEM's over the Head-Fi forums and came to a conclusion that the Head Direct RE-1 is going to be my best bang for the buck .I purchased it for $89(Thanks giving and Christmas sale) and got it in less than a week .All thanks to Fang Bian of Head-Direct for the great service.

Here's a review of the RE-1.

[BREAK=Specifications]

Driver unit: 9mm
Impedance: 150 Ohm
Sensitivity: 103dB/1mW
Rate input: 10mw
Max. Input: 30mw
Frequency
response: 20Hz ~ 18KHZ

These are the official specs from Head-Direct. The specs do matter with the RE 1 as they have a staggering 150 ohms impedance, which means that they are not so easy to drive and need a portable headphone amplifier for them to outshine (I will talk about this later).

[BREAK=Packaging and Accessories]

The earphones were shipped from China through EMS on the same day I ordered and were delivered in 6 days flat .The earphones did not attract any custom charges as NZ customs don't charge duties for items up-to $500 NZD.The earphones come in a leather box which is similar to the older versions of RE2.It was packed really well with 4 layers of bubble wrap and kept in a cardboard box.

The accessories consist of a pair of white transparent L bi flanges, a shirt clip, 3 pairs of filters, normal S, M, L ear tips. When compared to the RE2 the ear tips supplied are less, but to get a good seal most folks use only the white transparent L bi flanges.

At $89 i would not ask for much but it would have been great if all the ear tips similar to the old RE2 are included ie-(1 S-bi-flange, 1M-bi-flange, 2 transparent and L bi-flanges) .Also one wouldn't want to ill-treat any of their high end IEMs so the least Head direct can do is add a cable winder and a soft carrying pouch to their high-end IEMs.

I would rate the package as 8/10.

[BREAK=Design and Build Quality]

The design of the earphones looks similar to the head-direct RE2.Its piano black finish which it a metallic look. The earphones are very light weight and you can plug them in your ear's for long music listening sessions without any discomfort .First time IEM users might need to try out all the different ear tips and use the one which provides the best balance between comfort and isolation.

The cable is fabric knit which reduces micro phonics to a great extent and the extra coating also prevents the cable from damage. The 3.5 mm connector is a right angled one and the main cable splits at the centre for separation of left & right plugs.

If you observe closely the rear of the ear plugs has small circular vents similar to that on the RE-2.Just that the metallic plate with the vents is golden instead of the silver on RE-2.The vents mainly help in a better bass response and now a day’s most IEMs incorporate small holes or vents in the IEM housing. Also the gold finish on the RE-1 makes it slightly more flashy and noticeable in public.

The RE1s have better drivers than the RE2's which is pretty obvious when the price different is so huge. They are aimed at people like me who crave for the ultimate audio experience in a small package. The RE1s are made to suit a niche market where only a relatively small amount of people who are willing to sacrifice portability and money to get a good portable sound rig.

Design and build quality 10/10


[BREAK=Performance]

I was curious to test them in my laptop with creative X-fi USB sound card instead of the D2 ,so I hooked them to my laptop right out of the box and they sounded much more neutral and balanced compared to my RE2.I thought the RE-2 were really good with mids but it’s the RE-1 which has a really smooth and perfect mid range. The sound is very laid back and smooth. It’s sort of perfect for my Sonics tastes .The sound reproduction is perfect , crystal clear and no noise at all .The detailing and sound stage is on a totally different level altogether .

Ohhh yes they sound little bass shy out of the box. After listening to few trance and EDM tracks i felt these things certainly need an amplifier. I went ahead and plugged them to my Cowon d2+ which has one of the best sounding DAP .Music was very laid back ,the vocals are amazing. I tried listening to few track of A state of Trance radio show by Armin Van Buuren .The sound stage is so awesome, that you feel as if you are right there in the studio.

Now since its a dynamic earphone it certainly does need a good burn-in. I kept them for ~200 hrs of burn-in with pink noise and white noise. During this 1-2 weeks of burn-in I also went out looking for a better amplifier to pair with the RE-1 cause from what I had been suggested by other RE-1 users, the RE-1 needed more juice and power to show their true capability.
I did have the Fiio E5 but unlike the RE-2, the E5 didn't do any wonders with the RE-1.The pairing of RE-2 with E5 is like a match made in heaven but I can't say the same for RE-1.The E5 with RE-1 just sounds bloated and the only difference is the increase in volume .There isn't much change to the sound signature as such and the bass sounds artificial.
So I posted few threads on head-fi for suggestions for a better amplifier. I did not want to spend too much on it and wanted the best under $100 for a second hand amplifier. I was suggested Meir Corda 2 move or the 3 move, Mini 3 and the JDS Labs cMoy Bass Boost amp.The more you tried getting information from audiophiles from head-fi the more you get confused:S.
I was in total dilemma with the choices I had ,spoke to Brendon(BF1983) on TE to take their suggestions. Brendon who himself uses a RE1 told me that do not spend too much on a headphone amplifier as of now as it would be my first headphone amp .So I decided to keep the budget low and Brendon suggested me to pick up the Cmoy amp Luckily a head-fier was selling of his JDS Labs cMoy for $45 AUD shipped worldwide :).Had few conversation with him and picked up the amp. Let me not discuss n dept about the amp. Below i have attached a snap of the amp and a link for you to hover to JDS labs and check the specifications.

Testing After 200 hrs Burn-in

Without amp :All the songs were sounding really good but the volume was low and bass was not upto the mark .The Cmoy boosts the volume level and since its a bass boost amp once i toggled the bass boost switch and the bass shined out. Overall clarity increased by 40% and the best part with the amp is that one can change the op amps to suit your music taste. I was using the default op-amp which could satisfy the bass head within me.

Here are my test tracks ( all of them at 320kbps or FLAC's) .I am using the cMoy BB Amp with the Cowon D2+ .

Trance:Global DJ Broadcast ( 1-10-2009-Birmingham)-Live gig.

Some tracks in these shows have some amazing bass, especially the tracks Koolhaus (Markus Schulz Big Room Reconstruction) was sounding amazing .The mids were smooth and perfect and bass was punchy and tight. Songs which had vocals like the Nothing at All ( Elevation remix) was sounding brilliant. As I mentioned earlier the complete sound signature is very laid back and a little airy .Sound stage is like super wide and makes you feel as If you are present at the live gig. The sound stage is one of the best i have seen by far and the best assets of the RE-1.

Rock/Hard Rock/ Metal/Heavy Metal:

Scorpions -Rock You Like A Hurricane
Metallica -Nothing Else Matters
Oasis -Wonderwall
Children Of Bodom - Lake Bodom.
Godsmack-I Stand Alone

With this genre i had goose bumps with few songs as they were sounding heavenly, I could hear guitar picks very clearly for example in the song, Nothing else matters ( all of us know its an amazing song) ..Vocals sound sweet and natural. The highs aren't even one bit bright or sharp. Though the high's are not very detailed , they do the job pretty well . The sound is somewhat balanced , smooth and laid back .It makes you truly enjoy the music and there were moments I really went crazy listening to some tracks.

Hip-Hop:
Pitbull feat.Lil Jon - krazy
Pitbull- Hotel Room
David Guetta-Sexy B**ch (Ft. Akon)

Hip-hop is one genre I am not a big fan of , but I do listen to some particular tracks once in a while.It's also one of the genres which demands good speed and bass,lots of bass. The RE-1 with an amp easily satisfy the bass but the speed could be a little better. It's mainly due to the laid back sound signature I guess. Nevertheless hip-hop tracks do sound good if not the best with RE-1.

[BREAK=Sound Quality Continued]

Hindi:
A.R .Rahman -A world of Music

A.R .Rahman -A world of Music is a 3CD collection of some of the best tunes by the maestro. I tried out some of the classics like Telephone Dhun,Kehna Hi Kya,Dil se, rang de basanti tracks etc. The quality of music is truly amazing and remarkable. Each and every note can be heard crystal clear. For the first time I could here the finest detailing of the tracks which wasn't revealed in the RE2.It's like re-discovering your music collection.

On the sound part as I've already described earlier the mids flow though like liquid .It has a slight warmth to it and the bass is light and punchy with classical tunes. The high's compliment the mid range without adding any sibilance ,brightness or being too sharp.I feel the high's are bit laid back as well and could be more detailed .

I had few funny moments with the RE1's.I had listened to the Global DJ Broadcast Denver USA ( Trance lovers would know why i am talking about this gig) .I had hooked them up to my laptop with the amp.I was screaming at top of my voice all of sudden because of the awesome feeling of being there at the live gig .. The goosebumps moment thanks to the awesome sound stage.My roomies thought i had gone mad :ashamed:.I had tough time explaining them what happened .

The overall sound can be summarized as detailed and smooth warm mid range, punchy bass and decent highs.A completely laid back sound with really wide sound stage.


Sound Quality
8/10 without an amp
10/10 with an decent amp.


[BREAK=Value and Conclusion]
With the price of $89 shipped worldwide these are one of the best earphones ,They used to retails at $199 sometime back.They are worth every money spent.These are perfect for someone taking thier first steps in audiophile quality music . They are not for someone looking at completely neutral and accurate sound ,for that the RE-0 might be a better choice but for some looking at a nice musical pair of IEMs the RE-1s are definitely to be considered.

My Old setup( Now i have a iBasso D4 Mamba:ohyeah:,will be writing a review on the same in a month or 2 )

Nice Review!! :D

The shipping by head-direct is extremely fast :) , I received on the 2nd day of placing order by EMS.

The only crib with the build quality is the use of paper filter on the nozzle. It tends to get damaged easily while changing tips :/ Although there are many extra filters given still something more durable is preferred.

Considering a good amp is a must to enjoy these to full potential its not exactly VFM if you already dont own a amp :P
