Up until now, if you wanted a truly luxury smartphone, Vertu was your likely first port of call – but now there is the Solarin by Sirin Labs. This £9,500 mobile features some fine specs as well as “military-grade” security as a result of partnerships forged with Zimperium and KoolSpan, a company that specialises in mobile voice and messaging security. This means that the Solarin utilises similar technology militaries deploy to encrypt communications. Best of all, Brogue loves that fact all this spy tech is activated by a “Security Switch” on the back of the handset. For veteran travellers, 24-band LTE compatibility means you can use this mobile practically anywhere. Other tech wizardry abounds, including a 2K screen, Gorilla Glass 4 and a 23.8-megapixel camera with laser autofocus and four-tone flash. However, audiophiles might appreciate the three on-board bass-boosted speakers, tuned to maximise volume while eliminating any unwanted distortion. Fashioned by renowned industrial designer Karim Rashid, the Solarin’s composite chassis features titanium panels and a leather back. Available from 1 June in four models: Fire Black Carbon Leather with Titanium; Fire Black Carbon Leather with Diamond-like Carbon; Fire Black Carbon Leather with Yellow Gold; Crystal White Carbon Leather with Diamond-like Carbon.
