    Earsonics SM3v2: Really crappy bass on iPod

    So I recently bought some SM3v2's according to some advice I had received on a thread I made and some research.   Everything seemed to be going well with them until I decided to try something.   I switched the EQ from "off" on my iPod classis to "Electronic" and all of the sudden it...

    Hi all,   I'm looking to get myself some new headphones.  These will be my first pair of dedicated, portable headphones, so they need to be closed.  Currently I am using the CX 300-II IEM and they're showing their age.  I listen to a wide variety of music such as house, electronic...

    Review: Alclair reference monitor CIEM

    Alclair Reference Monitor review:   I recently decided to enter the world of custom IEM's, and decided to go with Alclair because of Average Joes multi custom IEM review, and the price. I soon found out that they have excellent customer support and was impressed with the way they treat their...

    Detailed + Forgiving + non-fatiguing?

    Detailed + Forgiving + nonfatiguing?    Is this a real combination?   I liked the silky smooth mids and forgiveness of my Re262, but the detail of my HF5.   Unamped or with a JDS Labs c421, what are my options under $200?   Thanks

    Increasing bass for W4R

    Hi guys,   Just got a pair of W4R. However, coming from ATH M50, I find the bass lacking in W4R. Is there any ways I can increase the bass? I'm using star tip. The foam tip seems to increase the bass, but for comfort, I'll prefer the star tip, Any advice?

    Replaced my TF10's with W4R's and I 'might' not be in love :shrug:

    Hello All,   My TF10's with a lune cable were destroyed a year ago.  I finally got around to replacing them.  I decided on the Westone 4R's.  Unfortunately I can only compare them to my memory of the TF10's.  I remember the TF10's being much more engaging and detailed.  Is there anything I can...

    Review: Fiio E12 (comparison to C&C BH + JDS Labs O2 + JDS Labs C421)

    I'm sure many are pondering about these two portable powerhouses. So this one is for you.   First off, some size comparisons: (taken directly out of camera without any adjustment whatsoever)           So, as you can see, E12 is almost roughly TWICE the size of C&C BH...

    Leckerton UHA-4 vs JDS Labs C421 vs FiiO E17 (E12?)

    Hey guys so I'm looking for a portable amp to drive some of my IEMs through my ipod touch and was wondering which would be the best value and performance out of these 3 amps. I've read that the UHA-4 and C421 are very closely similar and the E17 has the most features out of the bunch. Also the...

    Headamp for Shure SRH-1840

    Hi all,   Just joined this forum to ask this:)   I've just ordered Shure SRH-1840 and I want to do them justice by getting a descent headamp as well.   The first question probably should be, do you need to buy a dedicated headamp for these 65 Ohms headphones?   If the answer is...

    Best dedicated desktop amplifier for a DT990 used primarly for gaming?

    For my computer audio I've been using a Creative X-FI Titanium Edition, Berrydynamic DT990's 350ohmz, and a Fios E11 Portable Amp. I'm getting annoyed changing out the batteries to the portable AMP so often, so I would like to switch to a dedicated desktop amp. Additionally, I figure a better...

    JDS LABS Objective 2 with Titanium HD and DT990 250OHM Combo?

    Hey guys this is the setup I have pretty much been thinking about going with. I already have the Ti HD driving my AD700s. But want an upgrade.   Would the OB 2 source be plugged into the 3.5 mm jack? Or the RCA outputs on the soundcard?   Any help would be great. Any advantages to the...

    ATH-M50s revived my love of hi-fi audio. Now I want an affordable, portable amp for ALAC.

    I just listened to Radiohead's Kid A over these without even breaking them in using my Native Instruments sound card. Boy was that a pleasure.   I used to have a crappy headphone amp I'd route out of an iPod Classic (using the iPod's DAC) to some Denon AH-D2000s. This sounded pretty bad...

    Quick question about the Fiio E17

    Hello,   I am looking into getting a Fiio E17 and just have a few simple questions. I'm a beginner when it comes down to this sort of stuff so excuse me if these are silly questions. Since the Fiio E17 is a USB (and headphone) DAC/AMP that means I can plug it into my computer USB jack and...

    What to get for Christmas?

    The title says most. I am wondering, what you would get, if you were me. The budget is around 350 dollars, and alternatively I can get my money back on my new dt-880, which would get me approximately 350 dollars extra.   I would really like a CIEM, but i am only 17, so i guess it would be...
