Yes, both the AAC and the aptX codecs are supported. aptX HD and aptX Low Latency are not supported. Please note that N5005 is an in-ear headphone capable of extremely high audio reproduction quality. Wireless transmission cannot deliver the quality that a first-class analog, cabled signal can. The best possible quality is available with the balanced 4-pole 2.5 mm jack, connected directly to a highest-quality headphone amplifier that supports this connection, fed by the highest quality source.
