Many high-quality Bluetooth headphones use the favored aptX codec for Bluetooth audio – properly, it’s common with Android customers, Apple has averted aptX for years (probably due to a long-running patent dispute between Apple and Qualcomm, which owns the aptX know-how).
Fortunately, many of the finest Bluetooth headphones and earbuds help Apple’s most popular AAC codec, so you’ll be able to nonetheless use Apple gadgets with a variety of Bluetooth headphones, however many individuals argue that aptX offers superior sound high quality, particularly for listening to the lossless or hi-res music that’s now out there on Apple Music and different streaming companies.

Sennheiser says that the dongle’s aptX Adaptive can deal with hi-res audio codecs as much as 24-bit/96KHz, so it’s possibility if you wish to hearken to lossless or hi-res music.

The HDB 630 can be utilized with Bluetooth or wired connections, and in addition features a USB-C adaptor for aptX as properly.

Some folks will argue that aptX doesn’t sound a lot better than AAC, however I may hear a transparent distinction when listening to the hi-res model of The Beatles’ Eleanor Rigby on Apple Music. With the BTD 700 dongle plugged into my iPad Air, the sharp, stabbing strings sound extra forceful and dramatic, and the deep cellos particularly have a richer, extra resonant tone than when listening by way of the iPad’s commonplace AAC connection.
The dongle additionally does an awesome job with the dense rock sound of Sing Alongside by Sturgill Simpson, laying down a deep, grinding sound for the fuzzy rock guitars, but in addition choosing out the high-quality element of the ticking percussion that holds the observe collectively.

Our solely criticism is that it wasn’t solely clear find out how to change between utilizing the built-in Bluetooth with AAC on my iPad Air, and the aptX Adaptive possibility with the separate BTD 700 dongle plugged into the iPad.
It took a couple of minutes of random button-stabbing earlier than I managed to attach the headphones to the little dongle. As soon as that’s carried out the Sennheiser app lists the BTD 700 and the iPad’s commonplace Bluetooth as separate connection choices, making it simple to modify between them, however it might assist if the directions in Sennheiser’s PDF guide have been a bit of clearer.
The Sennheiser app has additionally been up to date for the HDB 630, with a brand new parametric equaliser that gives extra high-quality management over particular person frequency bands, and improved controls for the noise-cancellation options.
