Add aptX lossless streaming, Auracast broadcasting and low-latency audio gaming to your Bluetooth audio experience \u2014 that\u2019s Sennheiser\u2019s proposition for its all-new BTD 700 USB-C dongle.<\/p>\n

The BTD 700 is equipped with Bluetooth 5.4 and connects as a class-compliant audio device to its host to transmit audio to a nearby Bluetooth receiver i.e. a pair of Bluetooth headphones. The 2.4cm dongle (and optional USB-A adaptor) will work with any laptop, PC, smartphone or tablet.<\/p>\n

Google translated from the German press release, \u201cThe BTD 700 supports aptX Lossless and aptX Adaptive codecs for reliable, high-resolution wireless audio with up to 24-bit depth at 96 kHz.\u201d\u00a0<\/p>\n

Some points of order are, err, in order:<\/p>\n

1. Hi-res Bluetooth is not the same as the hi-res streams we pull down from Apple Music, Tidal or Qobuz using wi-fi or Ethernet. No Bluetooth codec on the planet can handle hi-res audio losslessly. aptX Adaptive will always discard some audio data to fit the audio stream down the Bluetooth \u2018audio pipe\u2019.<\/p>\n

2. That Bluetooth pipe is just about wide enough for lossless CD-quality audio but there\u2019s a catch: the receiving headphones must also support aptX Adaptive with<\/strong> aptX Lossless<\/a>.<\/p>\n

3. aptX Lossless is the uppermost tier of aptX Adaptive and will only be engaged if and when the environmental conditions are favourable.<\/p>\n

4. In the event of Bluetooth congestion or interference, aptX Adaptive will auto-magically step down to a lossy level to keep the music playing. The end user has no control over the auto-magical stepping up and down.<\/p>\n

5. Sennheiser\u2019s Bluetooth headphone app tells us when aptX Lossless is in play (and when it isn\u2019t) but other manufacturers\u2019 apps do not.<\/p>\n

6. Sony\u2019s LDAC codec \u2013 found in every modern Android smartphone \u2013 uses a similar three-tiered approach to Bluetooth streaming. It auto-switches between 990kbps, 660kbps and 330kbps and is therefore always lossy.<\/p>\n

The BTD 700 is available now for \u20ac50.<\/p>\n
