After reading the review I was like.
So with a few clicks I went to Amazon and got it for € 80 with the coupon. I don't use the app equalizer because I'm an equalizer snob and want a full parametric equalizer with adjustable Q. Technically speaking this is the ratio of the center frequency to the bandwidth. Simply put increasing the Q narrows the bandwidth, and decreasing the Q widens the bandwidth. (well, duh)
the android app Poweramp Equalizer has all that and more.
Low Pass/High Pass - passes the signal starting from the defined frequency, resonant with higher Q factor
Low Shelf/High Shelf - similar to Low Pass/High Pass with a flatter frequency response
Band Pass - passes the signal around user defined frequency
Peaking Band - narrower version of the Band Pass
Oh and If you have more than one wireless headphone (guilty as charged) you can apply an individual EQ profile to each device.
I have used the windows software of the same company for years as a Music Converter/CD ripper with multi core enabled batch processing. I painstakingly ripped my entire CD collection (500+) to FLAC and dumped the files on my NAS. What can I say? My autism brain just loves tedious jobs. To make things even harder on myself i had to make sure the files were properly TAGGED so the resulting database is searchable. For my smartphone I converted some of my favorite tunes to AAC to save some space. I can't hear the difference if the bitrate is high enough let's say >192 kb. (variable bitrate mode) But in hindsight this was unnecessary because my phone has a Micro SD card option. I could have spared me the extra work by putting an 128 Gb micro SD card in my phone and be done with it. Oh, well. But i only use local files if Wi-Fi isn't available because In that case I can just directly stream my files from my multiple Cloud storage providers and if that doesn't work my NAS is of course also accessible from the internet.
As an IT nerd I have to mansplain this over and over. You don't want a single point of failure.
Redundancy is key. In other words: make <beep> backups of important stuff.
I have encountered many unfortunate less tech-savvy souls who lost all their data because the hard drive in their laptop or PC failed. You will not survive in this mad world without some basic IT skills. Memory sticks, hard drives and even Solid State Drives will eventually fail at some point. With a NAS you can use RAID (redundant array of independent discs) options to reduce data loss due to drive failure. This does not mean you can skip making backups. With RAID only the probability of data loss due to drive failure is reduced, Data loss due to viruses or user errors, e.g. overwriting a file or deleting it, is not.
Hope for the best, but prepare for the worst. If that makes you anxious:
Xanax is your friend
No I wouldn't recommend that. Benzodiazepine withdrawal is no joke and can be fatal. Just trust me. Focus on the things you can control and let others worry about the rest.
DATA is LIFE
