Wireless earbuds focus on sound quality? Really? Both aptX HD and aptX Adaptive are lossy.

Qualcomm have recently announced aptX Lossless, which if/when adopted may mean we finally see some lossless CD-quality wireless headphones and earbuds hitting the market in 2022...ie well after everyone including What EarBuds have tried to sell you their crappy lossy stuff this Christmas.

Or of course, you could invest in a wired solution.

Hey bristollinnet! I’m EvShrug, community manager for grell.

Have you heard of LHDC? It’s a higher-res Bluetooth codec developed by Savitech (popularized by HWA) with the unique benefit that you don’t need a phone with specialized hardware; you can download apps like the FiiO player or HiBy player to either Android or iOS devices, and more apps are currently being developed. That’s why we chose LHDC! While CD-quality FLAC is sometimes called lossless, I think we can agree it’s “less loss” not Hi-Res lossless, but still CD-quality is a welcome improvement.

We’ve also spent a lot of time on the earbud’s timbre, avoiding sibilance, evolving past a flat robotic sound, no background hiss, and also incorporating a stock grell tuning which is warm without bleeding over mid details. This sound quality is even evident with AAC and aptX! We were also able to use the ANC to improve sound quality.
