Description

Beyerdynamic DT 770 PRO 250 Ohms

The legendary DT 770/880/990 series dates back to 1981 when the DT 880 model was released - the first dynamic headphones with electrostatic characteristics. Following that, in 1985, the DT 770 and 990 models were introduced, completing the series and providing maximum flexibility and choice to the market with closed-back (DT 770), semi-open-back (DT 880), and open-back (DT 990) headphones.

Features:

  • Studio headphones with excellent frequency range response
  • Bass Reflex technology for more voluminous, "breathing" bass
  • Impedance of 250 Ohms
  • Comfortable fit due to adjustable padded headband and soft velour earpads
  • Durable spring steel headband
  • Among the most reliable professional headphones, easy to maintain as all parts are replaceable
  • Coiled single-sided cable made of oxygen-free copper (99.999%) with gold-plated 3.5mm jack connector

The initial versions of the headphones had a plastic headband, which was durable but not as much as needed. In the early 1990s, the first professional models (PRO) were introduced, featuring a spring steel headband, aluminum forks, and an extremely sturdy ABS plastic body. This Beyerdynamic lineup has since taken the world by storm. Today, you can find DT 770/880/990 headphones everywhere: in recording studios, live broadcasts, the homes of music lovers, and audiophiles.

The closed-back Beyerdynamic DT 770 PRO dynamic headphones were designed in line with the requirements and preferences of professional sound engineers and performers. For over 20 years, this model has been a standard in the professional audio industry! Specifically for studio or stage work, the headband of the DT 770 PRO model ensures more secure fixation while the velour earpads and lightweight design enable comfortable extended use.

These headphones are renowned for their excellent noise isolation, which is essential when working with highly sensitive microphones. The low-mass sound coil paired with the DT 770 PRO membrane produces sound comparable to more expensive electrostatic headphones. Additionally, the Bass Reflex technology in the headphones allows the diaphragm to "breathe," resulting in better reproduction of low and high frequencies (as the diaphragm can move much more freely).

While sacrificing a small amount of noise isolation from the surrounding environment, the already outstanding sound profile of the DT 770 PRO becomes even better! Combined with a carefully calibrated frequency response, the model offers natural and balanced sound and comes in various impedance options (32/80/250 Ohms). These headphones excel with any music style or type of audio recording. Hand-assembled in Germany, the Beyerdynamic DT 770 PRO headphones are an excellent choice for professionals and anyone who values high quality and the impeccable, globally recognized sound.

Package Includes:

  • Beyerdynamic DT 770 PRO / 250 Ohms headphones
  • 3.5mm to 6.3mm jack adapter

FiiO K5 Pro ESS

Fiio K5 Pro Headphone Amplifier

Exquisite design and excellent assembly

Compared to the E series, the K5 Pro ESS has made a breakthrough in design and assembly, with tighter tolerances and better surface processing. The front panel is constructed independently from the rest of the body.

Every detail meticulously crafted

The FiiO K5 Pro ESS with enhanced decoding allows you to truly experience every moment in the smallest details. It acts as a bridge that enables your computer, speakers, and headphones to operate together, immersing you in a stunning concert hall experience right from your workstation.

Upgraded chip

The new XMOS XUF208 USB chip with a pulse synchronization generator delivers outstanding decoding performance. The new ESS ES9038Q2M DAC supports decoding with a sampling rate up to 768 kHz and hardware decoding of DSD512.

High-quality line output

In addition to a wide range of digital inputs, the K5 Pro ESS also features a traditional analog RCA line input. The RCA line input is not only more reliable and less prone to failure compared to the 3.5mm input but also offers higher resolution. The adjustable RCA line signal allows you to set a maximum value of 2Vrms, enabling the K5 Pro to be used with various active monitors and external power amplifiers.

Features:

  • New ESS ES9038Q2M chip
  • Three levels of gain
  • Output power of 1.5W
  • Recommended headphone impedance: 16 Ohms - 300 Ohms
  • DAC resolution: 768 kHz / 32-bit and DSD512
  • Headphone output: 6.3mm
  • USB-OTG function
  • Line output: RCA
  • Inputs: USB, optical, coaxial, RCA

5
The highest frequency, kHz

The upper limit of the frequencies reproduced by the device. The human ear hears the standard frequency range: 20 Hz – 20000 Hz.

Glossary of terms

Impedance, Ohms

No higher than 32 Ohms for smartphone headphones. When using a good player or amplifier, it can be up to 100 Ohms. For stationary models you should coordinate the impedance with the amplifier power

Glossary of terms

Driver type

Most of the headphones are dynamic but there are electrostatic, isodynamic, etc.

Glossary of terms
dynamic

Dynamic drivers use a circuit with a fixed magnetic system, in the gap of which a movable sound coil connected to a diffuser is placed.

Type of acoustic design

Open (with no insulation) or closed (passive noise insulation) or semi-open (intermediate version). Open headphones sound more airy and provide a wide stage, closed ones provide noise isolation and amplify low frequencies.

Glossary of terms
close
Cable length, m

The length should allow you to lay the cable with a small margin. The longer the cable, the more impact it can have on the sound.
