Just buy an iPhone. Oh no wait. No hole that decent headphones fit in. Have a 6s with a dicky headphone hole and some nice HD25’s. Not sure where to go. I feel like my time on this planet is nearly over.

Suggestion if you haven't: take a plastic dental pick and try to get lint out of the headphone jack.

I've had to do this sooner or later to every phone I've owned, except my latest, which lacks this port entirely.

Is Beats even good functionality? I heard they used mediocre components and spent most of their money on marketing...

The audio quality on my £110 wireless Beats X neckbuds is abysmal compared to a set of £30 wired Sony earbuds.

My kid has some wireless Beats headphones and she loves them because she likes how they look and they are very comfortable for her.

She might be able to find headphones that sound better, but she has never found any that also are comfortable and have good industrial design. At least not in the price range that Beats typically sell for.

> _It turns out that all music players on Android actually play music using the Android-media-player-service._ This is inaccurate. Neutron music player bypasses Android's Media Player APIs and talks directly to your DAC and plays music without resampling (if the DAC supports it). Never had any audio popping or explosions using Neutron, and I've tried it on 6 different devices so far without any issues (LG G3, Nexus 6…

It seems like bypassing the APIs which might screw up the audio with downsampling, and something like this is what the OP needed: https://www.audioquest.com/dacs/dragonfly/dragonfly-black Edit: would work out of the box with the Eee PC he has as well.

A 32 bit DAC is just a full on scam.

Except you’re leaving out all the positives and only focusing on the negatives. Sure, Google can revoke my access to a movie at any time but I can watch on any of my devices and I dont have to worry about finding it in stock at the local store. I can carry literally thousands of books with me in a device smaller than a paperback. I can’t stream lossless music from Spotify but I can stream high enough quality that mos…

The "positives" you've listed were basically the case for the standard 00's setup. You just had to undertake some deliberate action to adopt it as your setup, rather than going along with that period's sharecropper option.

How would you maintain access to your entire library across multiple devices in the 00’s?

IMHO your circuit topology looks wacky. Perhaps there's a goal to making your amplifier ground ride in the middle of the waveform, but it could just as well be unintentional. So my immediate thoughts - You've already got a real split supply with 2x 9v batteries. If you use that instead of deriving a virtual ground, you will save 9mA of quiescent current. How purposeful is that whole low side duplicated circuit and wh…

I think the trick here is that the resistors are much more precise than two batteries of unknown origin will be at providing a symmetric supply voltage without further stabilization. So they serve as a 50/50 voltage divider whatever the input voltage is, 7+9 or 6+8 on half full (or half empty, depending on your mental make-up) batteries, it would still work just fine.

Binding the central line between the two 9V batteries to GND would give you the situation you describe, indeed you could then drop the resistors but now you have a fairly high risk of ending up with an asymmetric supply voltage, which means one side will clip earlier than the other.

> Android is free software in the sense that you can make and distribute modified versions. I don't think that's enough to make it free software, and "free software in the sense..." is nonsensical. Free software would guarantee the continuance of that freedom. Since that guarantee doesn't exist, Google could place limitations on the Play Store at any time. The fact that they haven't makes the example less clear, but…

Play store isn't part of Android. Even if it was only available to specific phones, that wouldn't make Android unfree. Play store isn't open source at all. Amazon was able to take Android and put it on their extremely popular devices with 0 support from Google, no play store. That's what I call freedom

Play store isn't part of AOSP.

Boy does this person need to look at the ‘good headphone’ market. I paid (a very reasonable) $2k for a set of reference headphones and a suitable amp/DAC to drive them. I could have spent a lot more. It is hard to drive a set of headphones with enough SQ to make them worthwhile. You cannot plug a set of headphones into an Android phone and expect anything good to happen. And lots of DAPs suffer from software problems…

If you're over 12 you just wasted some money. Your ears are going downhill pretty much from the day you are born. Really good audio equipment is wasted on almost every adult.

I have a pair of powered studio monitors (Mackie MR5), and I completely relate to this problem. Many PCs and phones will emit an audible hissing noise while plugged in. I've tested on a dozen different devices, with integrated and external DACs, five hundred dollar sound cards, massively shielded cables, practically every modern OS you can name, tweaking every audio setting exposed to me. The only devices that work p…

Tidal has a lossless streaming service.

Not everything at the I recently got a £20 Havit Bluetooth receiver and connected it to a pair of £70 Sony MDR-7506 headphones. The receiver drives the headphones louder and with less distortion than my iPhone can, and the battery lasts for a few days of intermittent listening. Whatever loss is introduced by the aptX coding is invisible to my ears. I'm blown away by how good this setup is given the price and there sh…

I've been under the impression iPhones don't do aptX, did you find a workaround?

That would cut into the Beets business.
