Headphoneus Supremus
I guessed that may be true as the Aura cast update arrives in the spring but they could till have made them 5.4 same as Intel have.Update to 5.4 will come.
To print 5.3 on the box and promote them are one of the first earbuds to do 5.4 and retailers doing the same is not very good, hope they are better at updates than Bose with their broken promises with the QCII's.
