iFI Audio / GO pod + Ear Loop Pentaconn

iFI Audio/GO pod is a wearable Bluetooth adapter equipped with a high-resolution DAC and head amplifier. It is possible to make re-cableable in-ear monitors (IEMs) wireless. When paired with the right selection of high-performance IEMs, GO pod's high-quality circuitry can deliver sound far superior to any ""true wireless"" Bluetooth earphones or headphones.

■High resolution Bluetooth
- Also supports Qualcomm's 24-bit aptX HD and aptX Adaptive formats, allowing sampling rates of 48kHz and 96kHz, respectively, and QHS (Qualcomm High Speed) for a bandwidth of 300kbps. Other supported codecs include aptX Low Latency, regular aptX, AAC, and SBC. This ensures that all possible source devices are processed at the highest audio resolution within Bluetooth specifications.
