About this item

• 【A richer music experience】One set of headphones, two different sounds, dynamic(deeper bass) + balanced armature drivers(richer treble), metal sound chamber, 20-step process.
• 【Balance armature】A patented hybrid driver to let high notes sing and produces greater fidelity even for faint, high notes in a song.
• 【Dynamic】In order to deliver a superior sound in the mid and bass ranges, we sandwiched an aerospace-grade metal composite layer inbetween two PET layers. This preserves the outstanding treble responses of metal, while improving richness in the lower ranges.
• 【Four-time Grammy award winning tuner】Luca Bignardi, to perform a subjective acoustic tuning for Mi In-Ear Headphones Pro.
• 【Ear buds】Quality silicone ear buds available in 3 sizes(XS/S/L) so that you can find the perfect fit.
