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 recently got an ASUS Celeron N3350 based mini notebook which I want to use as a more personal stuff related computer, such as playing music etc. Will the 1.1GHz Celeron CPU on it run Equalizer APO well enough? Spec is similar to this:

Quote FiiO really dropped the ball on this one. Mine developed the same problem and the dealer said I had to return the whole package to get it fixed, so the cable is still languishing around. The Fiio guys said they would handle it themselves if the dealer insisted and I am yet to take up...

I am experiencing terrible microphonics with the AKG K371. When I wear a shirt the cable rubs against the collar too much. I think I need something like a right angled mini XLR male to mini XLR female connector, some other jig which turns the cable slighlty forward away from my collars. I've...

What are the settings needed to equalize the MSR7B to make it as "flat" or "reference" sounding as much as possible?

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 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. What third party earpads should I be looking at? It seems that earpads made for the Sony MDR-7506, the MDR-V6 and some other...

Are there any videos showing how connectors are soldered to the cables, and wiring diagrams? I suspect that soldering cables to MMCX, 0.78mm and all the other connector types is a quite fiddly process, delicate error prone process.

What equipment, parts and info do I need to make my own IEM and headphone cables? (UK) 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...

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...

It is not the earphone jack. It also gets disconnected in pavucontrol. That shouldn't happen unless the disconnection has been continued for a number of seconds. The same fault also occurs on the balanced connection.

Looking for equalizer settings for Yamaha HPH-MT8 I trying out a new Yamaha MT8 headphone and the sound just isn't right to me. Are there a set of equalizer settings that make it "flat sounding"? I haven't even been able to find a frequency response graph for it. I was looking for an upgrade...

There should be some on Amazon? https://www.amazon.com/Linsoul-Tripowin-Silver-Earphone-0-78-2-5mm-Grey/dp/B07ZQD54XR You can probably get something cheaper though by looking through the related items

My phone is a recent make phone but has a Micro-USB socket. Will a micro-usb to usb-c adapter enable it to work with the Fiio BTR5? I am talking about adapter cables such as: https://www.amazon.co.uk/FiiO-CL06-USB-C-Micro-Adapter-DIGITAL-Black/dp/B07DLQ2XYZ or...

There is a fault with my BTR5 which causes it to disconnect too easily when touched in DAC mode. It makes adjusting the volume so frustrating. The problem was present when it was new but because I didn't use it in DAC mode at the start I thought it was just the Bluetooth being flakey. Now I'm...

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...

@FiiO Kang What is the policy on damaged accessories? The L-bend in the cable came loose and the dealer is insisting that I return the whole unit for a repair or a replacement. Why can't I return just the cable alone? I even bought another cable and a cheap MMCX IEM just for the cable as a...

Do you have a link to the item you are suggesting?

The way ear tips suppliers layout their products on their website is so confusing. Even stating the exact measurements such as bore width, the length, and the widths of both ends seems beyond them. The bore is fine, it is the actual width I'm concerned with. It needs to be smaller than the...
