Dear Respected Customers, Ever since the release of our Apple Lightning Amplifier i1, the market welcomed it with great sales as well as favorable feedbacks. The length of i1 is about 80cm, if using it with standard earphone cables, the total length might reach 2m which is not so convenient to carry. Considering of this, we hereby release this RC-MMCX1s -- the replacement cable for MMCX plug headphones (short version). With length of only 60cm, it's still convenient to carry even use with the i1; with standard MMCX connector, it's compatible with many earphone models; 3.5mm single-ended plug; meanwhile, it's also compatible with some follow-up Bluetooth models, such as BTR1 and other related products. Check out the introduction of RC-MMCX1s by below pictures or >>Click Here The delivery of RC-MMCX1s to our worldwide agents starts this week.
