Audio-Technica ATH-DSR9BT Bluetooth Headphones

Key info

Audio-Technica ATH-DSR9BT over-ear Bluetooth wireless headphones supply your ears with Audio-Technica’s new Pure Digital Drive system, which allows the headphones to function without the sound-degrading digital-to-analog audio converter found in ordinary Bluetooth wireless headphones. With the use of new Trigence Semiconductor’s Dnote chipset, the ATH-DSR9BT headphones transmit the digital audio signal with the Bluetooth Wireless transmission and transfer the signal from source to the drivers, where the sound waves are created using the voice coil and diaphragm.

 

Audio-Technica Pure Digital Drive system, used in the ATH-DSR9BT wireless headphones, depends on exceptional and lightweight 45mm True Motion Drivers and purpose-built voice coils to bring superlative fidelity and extended 5 Hz – 45,000 Hz frequency response. The driver’s 4-core twisted OFC-7N voice coil brings accurate control of the diaphragm displacement, and the resistor controls the airflow around the diaphragm to ensure smooth sound reproduction across the entire frequency response range. Audio-Technica ATH-DSR9BT featured acoustic resistors are used to govern the airflow in front and behind the diaphragm to deliver a pure, well-balanced sound, and the entire driver assembly is housed within a layered aluminum structure that helps to minimize undesirable response.

In addition, the Pure Digital Drive system allows the ATH-DSR9BT to transfer the signal from source to the driver, overcoming the sonic limitations of common Bluetooth wireless transmissions by supporting the 24-bit/48kHz Qualcomm® aptX™ HD codec. The ATH-DSR9 Bluetooth Wireless headphones also come with the 2.0 m (6.6′) USB cable that allows to reproduce high-resolution audio when connected to a PC or any other digital playback device.

Audio-Technica ATH-DSR9BT headphones feature volume control, a microphone and tap control for playing/pausing music or answering calls on a smartphone or any other device paired with the headphones. The LED indicators represent the codec in use, pairing and charging status – the battery provides approx. 15 hours of continuous use (up to 1000 hours in standby mode) of ATH-DSR9BT model.

About High-Resolution Audio
In Brief: The Move to Hi-Res Audio
There is common belief that Hi-res audio is associated with the introduction of the CD in 1982. However, the limitation on the CD memory space always kept the audio (standardized at 44.1 kHz/16-bit) from wholly reproducing the original recorded sound, as well as the subsequent birth and rise of MP3s only made this problem more noticeable – the compression of audio files made the quality of sound to fade away, thus greatly reducing listening experience. However, with lossless audio file formats (FLAC & ALAC), faster Internet speeds, and general increase in devices storage space the push is on to produce audio equipment capable of transmitting and reproducing true High-Resolution Audio, which is considered to be at least 96 kHz/24-bit. The Hi-Res Audio logo certifies that a product meets the Hi-Res Audio standards. Per these standards, the audio equipment must have transducer frequency performance to at least 40 kHz. As a premium manufacturer of Hi-Res audiophile equipment, Audio-Technica is well-positioned to create headphones, such as ATH-DSR7BT that meet the requirements of Hi-Res Audio media formats, allowing for the complete reproduction of their extended sonic characteristics.
