To those who ordered: I’d be very curious to know if these suffer from Chronic Bluetoothitis* as nearly all Bluetooth headsets (except one or two) suffer from.
Looking forward to your reviews.
————————
* Chronic Bluetoothitis: a condition afflicting Bluetooth headphones whereby compression artifacts are audible to this human’s ear. Picture a FLAC file lossy-converted to 192 kbps mp3, then the lossy mp3 itself again reconverted to 128kbps or lower, thus losing even more dynamic range as well as low and high frequencies within the audible spectrum. I’ve found this condition to affect Bluetooth headsets like the Sony WH-1000-XM2 & 3, Bowers & Wilkins PX and P7W, Shure AONIC 50, Bose QC 35-II, Sennheiser PXC550 & Momentum 2 Wireless, Audio-Technica ATH-DSR9BT, Panasonic RP-HD605N-K, NAD Viso HP70, KEF Space One, Pioneer SE-MS9BN(B), Focal Spirit Wireless, just to shame a few but the list isn’t complete. Wireless earbuds affected include the Jabra Elite 65t, Beoplay E8 (one of the least afflicted), Sony WF-1000X, Samsung Galaxy Earbuds, and various Bluetooth earphone cables from Mee Audio, Westone, and others. The condition is present on all formats tested (SBC, AAC, aptX, aptX-HD, LDAC), with a variety of sources (bluetooth DAPs from Fiio, Sony, Cayin, others; iPhone, plethora of Android devices from Samsung (S9), ZTE Axon 7 Mini, LG G7, Sony Xperia something or other, and Huawei P20 Pro) and occurred regardless of source format (usually FLAC, 320kbps mp3 or 256/320 kbps iTunes/qAAC-converted AAC)
The only headphones which mostly escaped this affliction so far have been the Beyerdynamic Amiron Wireless and AKG N700NC
