My Anker Q30 is not charging properly. No matter how long I charge it, when I turn it on I get the message "Battery low" and it is less than a year old. Is there some way to replace the battery, or will it be easier sending it to Anker for a fix? I think it should still be under warranty.

I need some earpads to go with the DT-250. Their clamp force is to high and I need thicker softer earpads which will push the drivers farther away from my ears. It will be good if they are also larger which means less pressure and more comfort. What third party earpads should I be looking at...

I find virtually all the cables on my headphones too long as I often use portable DACs on my shirt lapels, top pockets and at my desk. I now have to make cables which whose maximum length is around my sternum, and I need them for MMCX, 0.78mm, 2.5mm, 3.5mm and what nots. Proprietary cables...

Do headphones sound better when the drivers are further away from your ear? I'm developing the sentiment that headphones sound better when the drivers are further away from the ears. When the clamp force is strong the pads seem to push hard against your ears and the sound feels "forced" and...

Hi guys, I' m looking for a closed-back headphone with sound signature of Yamaha MT5 but with more detail and top end clarity. I tried a few so-called closed-back studio headphones, eg Beyerdynamic DT-770, AKG K371, and they have a kind of "cupped" "boxy", "horny", "hollow" sound which seems...

I want to upgrade up from the AKG K371 and I'm looking for something in the sub $250 range. How does the Beyerdynamic DT880 and the Sennheiser 560S compare to it? In fact how do these two compare with each other. The DT880 is pricier than the DT770 and DT990. What are the other options in that...
