    ExFat vs. Fat32 etc

    As we use more and more DAPs nowadays, what is the preferred format for SD and mSD cards, and the relative pros and cons of each, when used in a DAP?    There are many articles on the relative technical merits of each but I'd like to focus on their relative merits as it pertains to actual...

    NFC vs BT - how much difference does it make to sound quality?

    Hi,   Purely on sound quality (not battery life, proximity, etc), how does NFC compare with the various BT flavors when "paired" with wireless speakers? I understand that NFC has a maximum speed of 400 Kbps and BT >1 Mbps (I don't know which flavor) and would this make a difference when...

    Game apps

    I am using an iPad to access head-fi.org, sometimes via Safari and sometimes via Chrome. For a while now, for no apparent reason, my iPad App Store will open automatically and show me a game app to download. It's usually the same few game apps. Now I have found out that these same game apps are...

    Faces behind the names

    In recent weeks, I have been very impressed by entrepreneurs who stand by their products and respond directly to your queries, thoughts and suggestions, whether via head-fi.org or emails. Foremost amongst them, M. Goodman (Centrance), D. Clark (MrSpeakers), D. Maudlin (Cypherlabs). Take a bow...

    Alternative ear pads

    Hi, I thought it might be useful to start a thread and reference source on what alternative ear pads one can use on headphones. Most will likely have an impact on the sound so do feel free to add your comments. I will start with those headphones I own and have changed the pads: 1. Sony...

    CD player to headphone amp

    Is it possible to connect the RCA Out on a CD player like the NAD C515BEE to a headphone amp? In addition, are there CD players with two pairs of RCA Outs and that allow you to flip between RCA Out to say that headphone amp and an integrated amp? Thanks.

    Grado SR325i with Beyerdynamic earpad

    Much as I adore my 325, I can't stand the S-Cush, L-Cush or G-Cush. I like the size of the G-Cush but it's itchy and easily slips off the back of my head. I put the S-Cush on the 325 and attach onto it a Beyerdynamic velour earpad. It's now the same size as a G-Cush but comfortable and stays on...

    Grado SR325iS on "skinnies"

    I have an old pair of Grado SR60 (without the i) and last year bought the SR325iS and upgraded the ear pads to the G-Cush. I kept on changing between the G-Cush and the stock L-Cush but didn't like both. Then I experimented by using my SR60 flat pads on them and just loved it. Weird. This was...

    Bookend-ing the HD600

    I have the Sennheiser HD600. I have read so much about the two models HD598 and HD650 that are just lower and higher (price, quality?) than the HD600. Would it be excessive to "bookend" the HD600 by also buying the other two? I would be very interested in the views of people who have owned all...

    Amps for HD600, DT880(250), SR325iS, K550

    Hi guys, I bought a Sennheiser HD600 today on impulse, just after getting a Beyer DT880 250 ohms a week ago. This adds to my collection of Grado SR325iS, ATH-M50, ATH-AD700, AKG K550, etc. My music is predominantly rock, Blues, R&B and are usually from my iMac in Lossless and 320. I have an...

    Too soft Beyer DT880 250 ohms

    Help! The Beyer DT880 250 ohms are my first high impedance cans (the others being Grado SR325iS, AKG K550, ATH-M50, AD700 etc). Using my iMac as a source, I find that my desktop amps (Fiio E10, Audioengine D1) have to be turned to maximum volume to reach a listening level of about 1/2 to 3/4 of...

    Flat down?

    Hi. I store all my full size headphones flat. Does it make a difference whether the earpads face up or down?

    A fully iPhone-compatible headphone amp

    I currently use a Klipsch s4i headphone with my iPhone 4S. The s4i has an in-line microphone so I can make and receive phone calls. I have been trying to find a portable headphone amp that will allow me to continue to make and receive phone calls when the headphone amp is connected in between...
