It is very easy to use and is capable of getting the most out of the 5K, controlling the volume, output

So far, I didn't really have to plug it to a charger during the day - the battery life is more than enough, even when I travel. Connecting it to a PC for some one-hour listening session in the evening replenishes all the juice it needs.The very transparent nature of the 5K makes sure that the user is essentially listening to the sound character of the earphones and not the source itself. IOS/ANDROID APP: 5K Mobile App enables the user to access every detail; Battery history, charger status, volume, DAC operating profile, DAC LPF filter, Equalizer, USB DAC sample rate, microphone gain, Bluetooth codecs. *5K is the only Bluetooth device that displays real-time LDAC bitrate. NOTE: The 2.5mm Balanced mode fully uses two ES9219C, while the 3.5mm unbalanced works with single DAC. This is the lowest battery life portable DAC i have ever had. I do use it in single DAC mode, not Dual which eat more power.

supports 96KHZ/24-bit USB audio streaming. USB Audio Class 1.0 / No additional driver needed. Windows, macOS, and Linux USB C-to-C direct connection with Android smartphones You can have it... For high-sensitivity IEMs, the amplifier noise figure is the most important. The high-sensitivity IEM is so sensitive that it translates every electrical noise or thermal drift into audible acoustic sound, usually white noise. Additionally, perhaps markings on volume buttons, though with mappable button this becomes redundant. The FiiO BTR5 2021 version is the closest rival to the Qudelix 5K with the same DAC chip configuration but it uses a separate XMOS XUF208 USB receiver that allows for 384kHz/32bit, native DSD256 and MQA decoding. has built-in mic and a great one at that. This enable voice call and even transparency mode (so-so in my experience, depend on where you clip it). I also wish it has some kind of IP water resistant rating since this is intended for on-the-go usage.This is a limitation USB Audio Class 1.0. On the upside – it ensures that the 5K requires no drivers and will run on almost anything with a USB port. You can simultaneously keep the app connections with a smartphone over Bluetooth and a PC over USB. So, with the choice of the right headphone the 5K can sound equally enjoyable with all kinds of music and will satisfy the most demanding of the listeners. High Sensitivity 3-dimensional LDS Antenna is printed on the bottom case and is placed around the red LED button. 5K provides the best RF performance in most use cases. However, for...
