Hello, After more than a decade I finally got into a really bad transaction with a seller here on HF. After I sent him payment and he didn't respond whatsoever in more than 24 hours, and i saw he was logged in a couple of times, I got spooked and posted a warning message on his listing (all of...

Hi all,   I have a pair headphones that unfortunately got zapped by a very decent spike of DC voltage from a certain valve headphone amp, which caused a very loud 'PoP' sound. I ran a tone sweep and don't detect any distortion, and also no channel imbalance, But i do subjectively feel that the...

Hello fellas, I have a predicament with my right ear that pretty much requires keeping the ear canal dry at all time, or at least keeping outside water from entering. So I'm looking for earplugs that are basically water repellent. I've been quoted by an audiologist at about 115$ for customized...

Hello,   I'd like to use my obj2 as a basic preamp solution to boost the input level to my Parasound Zamp v3. Simply connectiong them obviously yields a rather distorted and dynamically flat result. I've read that the pre-power impedance matching ration should be 1:10 so i'm guessing i'd...

Hi guys,   I've just ordered some T20's on Amazon, Problem is i forgot that i'll be plugging them to a 230V outlet so i'm hoping that the AC adapter is universal voltage... It's not shown in the specs unfortunatly. If anyone can comment asap i'll very much appreciate that so i can cancel my...

Bought a CM-130 Checkmate but i found that in needs to calibrated for proper results, Is there a way w/o using a calibration device? 

Hello, I'm considering The Auditor for the HD800 but since i won't part with my W5000's in the visible future it's crucial that the Auditor gets along fine with them. Did anyone who has heard both find that the inherent upper-mid/treble hotness (not harshness) of the AT's too much out of the...

As i understand the drivers in HP1000 series have paper type cones. Also correct me if i'm wrong but it isn't common material choice in driver diaphgram anymore... In this context i'm wondering how durable HP1000 drivers are, Not just to imbalance issues but also to physical degradation of the...

Hello to you all Head-Fiers. Which headphones are particularly good for watching TV, if there are any? I need them for my dad who tends to watch movies and stuff late into the night, not before arguing with mom over the volume, each and every time Also, there is this issue that most cans...
