Although to be fair, Google Glass was also pulled off the market when users started complaining of headaches, although their PR machine focused on the privacy issues, the real issue was that the high levels of electromagnetic (EMF) radiation via non-ionizing radiation, in the radio-frequency (RF) range in operation + the battery located right next to the brain + wifi signal, had unknown potential long-term side effects in that Google themselves advised that children not utilise their product. In the USA, the Federal Communications Commission (FCC) has set a SAR (Specific Absorption Rate) limit of 1.6 W/kg, averaged over a volume of 1 gram of tissue, for the head. In Europe, the limit is 2 W/kg, averaged over a volume of 10 grams of tissue. According to the SAR Evaluation Report for Google Glass by UL CCS, the highest 1-g SAR in head for Glass is measured to be 1.110 W/kg, which comes from its Wi-Fi antenna. Since Google Glass has a SAR level below the safety limit of 1.6 W/kg, it is considered “safe” according to the FCC safety guideline. I'm not sure what the SAR rating is for the Oculus Rift googles, but I extrapolate that it's probably a little higher than Google Glass.
However, imho, the trend seems pretty clear that aside from SmartWatches, we are actually moving away from wearable tech. No one wants to be wearing glasses that give you headaches and lazy eye syndrome, and no one wants to be wearing a clunky set of googles that looks like a medieval torture device.
To be honest, I never even liked laptops simply because I was quite sensitive to typing on the heat-emanating keyboard which I felt interfered with my thinking processes. Back in the early 2000s, I would take an extra external keyboard with me on trips and connect the USB port into my laptop, just so that I wouldn't have direct contact with the laptop keyboard. When iPads came out, I was elated, because it replaced my laptop altogether, and its bluetooth keyboard was great, simply because I wasn't absorbing all the EMF radiation from the traditional laptop keyboard.
In regards to wearable tech jewellery, and even SmartClothing, I'm not sure that I want to adorn a plastic, post-modern set of minimalist looking rings, bracelets and necklaces that tell me when someone is emailing, texting or ringing me, or even, monitoring my physical activity. Those aren't the must-have features for me. However, if my earrings and rings could do cool stuff, like project holograms and play music, then that could possibly be enticing, but I could probably just do that with my mobile phone, tablet or SmartWatch, and I'll leave the silky touch of gold, silver and platinum or even sapphires, emeralds and pearls for direct contact with my skin, rather than a device in which I absorb its EMF radiation.
