What is the difference between Hi-Fi Audio, HD Audio, and Hi-Res Audio?

Hi-Fi Audio is most commonly associated with audio perceived to be of "CD-quality." CD quality audio is music that is sampled at 16 bit, 44.1 Hkz

HD Audio refers to audio perceived to be of "higher" than CD-quality. HD quality audio is music that is sampled at 24 bit, 48 Khz

Hi-Res Audio refers to audio that is sampled at a much higher rate of 24 bit, 96 Khz or 24 bit, 192 Khz

What are Bluetooth Audio "Codecs"?

Codecs “encode” and “decode” audio using different types of file compression to send as much information as possible using the available speed and Bluetooth bandwidth. Much of what distinguishes a codec comes down to bit depth (bits), bitrate (Kbps), and sampling rate (kHz), with higher numbers indicating higher quality in nearly all scenarios.

Common Codecs:

SBC is the most basic codec with the lowest bitrate and, therefore, the lowest sound quality.

AAC is a step up from SBC and most common on Apple phones and tablets.

aptX™ audio technologies from Qualcomm® are also a step-up from SBC and designed to provide great sound for music, calls and more. aptX™ is the preferred standard for Android.  aptX™ is actually a number of codecs with different purposes. There's standard aptX, aptX LL (low latency) for gaming, and aptX HD for high-quality audio.

Additionally, while Qualcomm® launched aptX Adaptive in 2018 with 48kHz support, the codec is actually capable of wirelessly transmitting 96kHz files – the sampling rate studio music is often recorded at, and digital hi-res files distributed at. aptX™ Adaptive uses adaptive bitrate to offer a combination of lower latency and higher quality.

LDAC and LHDC enable even higher quality sound than those codecs, and are currently the only ones to which the Japan Audio Society extends its "Hi-Res Wireless Audio" certification

In our current product range, the Shenoy SH010 supports SBC and AAC while the Shenoy SH030 Elemental additionally supports  aptX™ and aptX™ HD

What is a “Lossless” Audio codec?

The term "Lossless" was essentially created to mean the opposite — of "compressed" or "lossy". All of the codecs described above are “lossy” – meaning these are digital music files that have had a lot of their details, specifically their high and low frequencies, stripped away in order to save space on your smartphone or computer.

The term "Lossless" doesn't mean uncompressed, however, but it refers to a type of compressed digital audio file that uses advanced data compression algorithms so that the audio track doesn't "lose" any detail in the compression process. When somebody refers to a "lossless" track, they typically mean that it's the same quality as a CD or vinyl record (16-bit/44.1 kHz).

Introducing aptX Lossless

aptX™ Lossless is a new feature of Snapdragon Sound Technology from Qualcomm®  that is designed to deliver Lossless audio quality over Bluetooth wireless technology. Claimed to be mathematically “bit-for-bit” exact, the technology supports 44.1kHz, 16-bit CD lossless audio quality.

Despite its lossless branding, aptX™ Lossless isn’t entirely compression-free. There’s still some compression at work here to bring 1.4Mbps CD-quality audio down to the 1Mbps bitrate that aptX™ Lossless is capable of transmitting. But the difference here is that the compression being used shouldn’t result in any loss of data and is “bit-for-bit” exact. After it’s uncompressed it’s exactly the same as the original (in a manner similar to a zip file - it gets smaller, but it’s exactly what it was when it comes out

aptX Lossless features & specifications:

  • Supports 44.1kHz, 16-bit CD lossless audio quality
  • Designed to scale-up to CD lossless audio based on Bluetooth link quality
  • User can select between CD lossless audio 44.1kHz and 24-bit 96kHz lossy
  • Auto-detects to enable CD lossless audio when the source is lossless audio
  • Mathematically bit-for-bit exact
  • Bit-rate – ~1Mbps
Do digital streaming services support “Lossless” Audio?

Yes. As of this time Apple Music, Tidal HiFi, Amazon Music Unlimited, Deezer Premium and Qobuz support Lossless Audio.

Spotify's first lossless streaming service, Spotify Hifi, was announced in early 2021 and was supposed to launch before the start of 2022 — but it's still not here yet.

How do I use the SH010 headphone with MS Teams on a Windows laptop?
  1. Power on the headphone by holding down the power button for 2-3 seconds until the power on button comes on. The headphone will automatically enter pairing mode with the flashing light alternating between blue and red colors.
  2. Launch the Bluetooth panel on your Windows PC as shown below:


  1. Select the option to Add Bluetooth or other device                       
  2. On the next screen, click on the first option for “Bluetooth”


  1. On the next screen, the system will automatically detect the available devices. Select the one called “Shenoy” that is displayed


  1. Click on the “Shenoy” icon displayed and on the next screen select the “Connect” button


  1. Once the device is connected, it will appear on the main Bluetooth screen as follows:


  1. Windows will also display a prompt on the bottom right of the screen as follows:


  1. In Microsoft Teams select the option for Device Settings. Select the device called “Shenoy Hands-Free AG Audio”. And you are all set to go


  1. If the headphone power is switched off (by holding the power button down for 2-3 seconds), and subsequently switched back on, it will automatically reconnect to your Windows laptop.
