Wired vs. Wireless

Earphones, earbuds, and headphones have become an essential item for many people today. But while they can do a great job allowing you to listen to music whenever and wherever you want, they also come with a few drawbacks. They can break relatively easily, the sound can glitch, the wires can get tangled, and if you get a wireless pair, they are extremely easy to lose.
A pair of wired earphones is a great choice for anyone who wants to have their headphones connected to their device at all times. These models are easy to use, they don’t have any battery to charge, and they are extremely useful for everyday situations.
Wireless headphones, on the other hand, are a little more complicated, but they can definitely be worth the effort. These devices are great because they let you listen to music wherever you go without having to worry about wires getting tangled or breaking in the middle of your favourite song.

Wire all the way. Bluetooth is part of the noise most of up are trying to avoid. Why would you want that to be the way your music is transmitted to your wonderfully new headphones? HiFiMAN is pitching Ananda BT. But they are in business to make money. Get the regular Anandas.

kijanki, appreciate your explanations and advice. I suppose few if any audiophiles enjoy a theoretically ideal setup. Just trying to make the best of my own circumstances, thanks for sharing.

hickamore, It's the wire, conducting electrical noise from computer or router/network to the DAC.  Even optical isolation in Ethernet network has few picofarads across - enough to inject some high frequency noise.  I would limit number of necessary wires (power wires for USB are not necessary if DAC is self powered) and use shielded cables to reduce pickup of ambient electrical noise.  I would also avoid placing network wires next to power wires. 

I'm not saying one method of delivery is better than another.  I use wireless, because I couldn't route Ethernet cable across the room.  I had a lot dropouts, until I switched to 5GHz band.

kijanki, what would cause a wired connection to inject noise into the system? I mean assuming a correct setup and assuming that all components are functioning as designed. Thanks.

WiFi might produce electrical ambient noise, that you most likely already have if you use wireless router, but wired connection can inject electrical noise directly into the system.  Also WiFi transmits only data and as such it cannot have lower or higher dynamics or amount of noise.  Important is what happens to this data later.  Data is most likely compressed, so it has to be decompressed and timing has to be attached.  In case of my Airport Express it comes out as 16 bit S/Pdif stream at 2x44.1kHz word rate.  DAC converter  can adjust/follow it for D/A conversion or just ignore it, rescan data and output it at new unrelated clock (upsample), as my Benchmark DAC3 does.

latik, thanks. That was my suspicion, but thought I should seek out community experience before dropping a pile of $$$ on Aurender or such.

A wired connection will always sound more dynamic and fuller vs wireless, IMHO. A wired connection pretty much immune to RFI/EMI and other noises as long as you’re using cables with proper shielding. In high quality audio systems, front end along with everything else matters.

Others here may disagree but WiFi is prone to transmit ‘noise’ present in your environment along with audio signal. Now if you’re using a subpar streamer /DAC then should you really care? In those systems convenience is more of a preference over audio purity.
