Wired, SBC, aptX, aptX (LL) Plantronics BackBeat Pro 2 We measured the Frequency Response and Total Harmonic Distortion of both headphones with aptX and again without aptX, using the default sub-band coding. Plantronics Backbeat Pro 2 Audio Test (SBC)Īs you may have noticed, it's difficult to tell the difference between SBC and aptX by ear. Plantronics Backbeat Pro 2 Audio Test (aptX)

Below are a few samples of the same headphones using aptX and SBC. However, the subtle audio quality differences may be noticeable to trained ears and more critical listeners. It's not especially lossy, and its latency should be suitable for most streaming services. The default sub-band codec (SBC) works well for most audio applications. Also, we have yet to test a headphone with the aptX HD codec. So, for now, our comparison will focus on the differences between SBC and aptX. We have yet to find a reliable way to measure AAC and LDAC over a wireless connection. However, it's a bit limiting, as both the Bluetooth transmitter and receiver must have aptX or its variations for the codec to work. There are also two additional variations, aptX Low Latency and aptX HD, that either drastically reduces the latency of the connection or significantly improves its audio quality. It's ideal for demanding audio applications since it encodes audio more efficiently and at a slightly higher rate than SBC. However, it's not very common, especially for headphones.ĪptX - A proprietary and optional codec designed by CSR. This codec is mostly popular with Apple's iTunes platform and some other non-wireless applications.

This is especially noticeable with a cheap Bluetooth transmitter.ĪAC - Advanced Audio Coding - Similar to SBC, but with better sound quality. However, the audio quality can be a bit inconsistent at times.

It provides fairly good audio quality without requiring a lot of processing power to encode or decode. It is capable of bit rates up to 328 kbps with a sampling rate of 44.1kHz. SBC - Sub-band Coding - The mandatory and default codec for all stereo Bluetooth headphones with the Advanced Audio Distribution Profile (A2DP). The 3 main codecs that most listeners are familiar with are SBC, AAC, and aptX: However, since this codec has a relatively high latency and may be a bit lossy, companies have developed their own encoding algorithms, like Samsung's UHQaudio and Sony's LDAC. The efficiency of the codec will determine the quality and rate at which the audio data is sent. SBC is the default sub-band coding for most Bluetooth devices. Codecs are encoding and decoding algorithms that compress audio into manageable data packets for faster or wireless transmission.
