Blade APEX2

The ZTE Blade APEX2 smartphone was a mid-range 4G phone. It was notable for offering HD voice call quality which was powered by NXP Software’s LifeVibes VoiceExperience technology which enabled “crystal clear conversations with higher speech quality and richer, more natural tones.” It was launched in Europe as a ZTE-branded device but was also marketed by Orange as the Hi 4G, and by KPN as the Smart 400.
