Why Audiophiles Choose This Product

• Bold, engaging sound made mobile
  HiFiMAN’s HIMALAYA R2R DAC architecture (a discrete ladder design) underpins BlueMini R2R’s lively dynamics, low noise floor, and natural timbre—traits listeners typically associate with high‑end desktop gear, now in a pocketable module. Reviewers consistently note improved resolution and clarity when switching from basic Bluetooth sources to the BlueMini R2R.

• Serious tech under the hood
  Built on Qualcomm’s QCC5124 Bluetooth platform and a custom HIMALAYA R2R DAC, the module supports modern hi‑res codecs (LDAC, aptX HD, aptX) alongside AAC and SBC. It’s a rare combination in this category, purpose‑built to maximize wireless fidelity.

• Practical, everyday convenience
  Weighing just 25 g, BlueMini R2R keeps your headphones comfortable and balanced. Expect up to 8 hours of playtime on a charge, plus the option to listen while charging via USB‑C. A single multifunction button and status LED keep operation simple.

• Versatile connectivity you’ll actually use
  Beyond Bluetooth, BlueMini R2R works as a USB DAC with most PCs/Macs and many Android devices (OTG). That means consistent, high‑quality sound at your desk or on the go—no extra dongle required. Note: iOS/Lightning connections may require Apple‑certified adapters and are not universally supported.

• Seamless fit with popular HiFiMAN models
  The module plugs directly into the left earcup’s 3.5 mm TRRS port on compatible headphones including DEVA Pro, HE‑R9, and R10D; it also retains the footprint of the original Bluemini for broad physical compatibility across supported designs. Always verify your headphone’s left‑cup TRRS port before purchase.
