We buy our own headphones and put it under the same test bench. This way we are able to compare the results easily. Our tests include listening tests, sound quality tests and durability tests.
Our team uses a variety of methods to measure audio performance including A-weighting, THD+N measurement, frequency response, distortion and noise level measurements.
The following graphs show the average values measured during testing.
A40 TR Headset
The A40 TR Headset from Audio Technica is designed specifically for DJs and electronic music producers. This headset offers high quality sound reproduction while being lightweight and comfortable to wear. With three different sizes and ear pads, it provides maximum comfort.
Click and drag to rotate
The A40 TR features a unique rotating design that allows you to adjust the angle of the microphone boom to suit your preference. You can easily switch between left/right side use and even flip the unit 180 degrees for easy storage.
The A40 TR is a compact wireless microphone system designed specifically for use with smartphones and tablets. With just one cable connection, you can connect up to four microphones to a smartphone, tablet or laptop via Bluetooth technology. The built-in boom mic allows you to capture sound directly into your device without having to connect it to a separate audio input jack.
The A40 TR features a high quality omni-directional condenser capsule microphone with a frequency response range of 20 Hz – 40 kHz, allowing you to pick up clear voice recordings even under noisy conditions. You can easily switch between recording and playback modes with a simple press of a button.
The included 3.5mm mini stereo connector allows you to attach the A40 TR to most mobile devices including iPhone®, iPad® and Android™ models. By connecting the A40 TR to a computer, you can playback recorded files on your computer or upload them directly to cloud storage solutions such as Dropbox®, Box®, OneDrive®, etc.
• Compact design fits nicely in your pocket.
• Omni-directional condenser microphone captures crisp, clean sounds.
• Built-in boom mic allows easy placement of the microphone close to the subject while still capturing good audio.
The Transducer Principle
The Transducer principle is one of the core concepts behind our design philosophy. We believe that every sound system needs a driver that enables it to deliver the best possible performance across the entire frequency range. This includes low frequencies, mid-range frequencies, highs and everything in between. Our goal was to develop a dynamic transducer that could reproduce all aspects of audio without compromising fidelity.
Our transducers are designed to cover the full audible spectrum, including lows, mids, highs and subsonic frequencies. The nominal impedance we use is 48 ohms, which allows us to connect up to 8 drivers together in parallel.
We chose a nominal impedance of 48 ohms because this value provides the best combination of efficiency and power handling. A lower impedance leads to less distortion and better transient response, while a higher impedence reduces efficiency due to increased voltage drop.
Each driver has its own dedicated amplifier circuit, so each driver delivers its own characteristic sound. The result is a rich, natural sound that’s free from harshness and graininess.
The sensitivity of our transducers is measured at 1 mW per 1 V peak output level. This means that the minimum input signal required to produce an acceptable volume is 0 dBm (0.01 mV).
Output Power Handling
Each driver handles up to 100 W of continuous power. In addition, each driver can handle up to 200 W peak power when connected in series.
Power Supply Requirements
All of our products require a regulated DC supply. The recommended operating voltage is 12 VDC.
Dimensions & Weight
The A40 TR measures approximately 5 x 2.3 x 1.4 cm / 2.1 x 0.8 x 0.5 inches. It weighs about 10 g.
The A40 TR comes with a 3.5 mm jack for connection to external equipment.
The A40 TR is suitable for use in applications where a compact, lightweight solution is needed.
The Apple Watch Series 5 is here, and it packs some serious improvements over previous models. This model features cellular connectivity, GPS, waterproofing up to 50 meters, and built-in Wi-Fi. The display now offers a resolution of 2160 x 1440 pixels, making it one of the highest resolution displays ever included within a smartwatch. Other notable changes include a dual-core S5 Pro chip, Bluetooth 4.2 support, NFC payments, and watchOS 6.1 software.
Here are the physical specifications for the Apple Watch Series 5.
Compared To Other Headphones
The Astro A40 TR Headphone is one of the most popular gaming headsets among gamers because of its excellent build quality, high comfort level, and reasonable price tag. While it doesn’t have many bells and whistles compared to some other models, it still delivers quite decent audio performance.
However, there are better options out there that provide more features and customization. So what makes the Astro A40 TR stand out from the crowd? Let’s take a look at how it compares to other gaming headsets.
