Why do people keep quoting that cons list for wireless like it is the definitive pros and cons. It isn't :-
Not exactly plug and play
Yep totally right it is not plug and play because there is no plug. It is however press button and play which is just as easy. Hell if my 75 year old mother can do it I am pretty sure most can learn how to use these apparently heavily complicated new fangled bluetooth devices.
Erm yes it is. As far as I am aware Blue tooth is a universal standard. You can use any blue tooth device with any other blue tooth device. Just like you can use a 3.5mm jack with any other device that has a 3.5mm connector
Legacy devices will need adaptors in the form of dongles, making them even less convenient and adding costs
OK you got me there but that is inevitable whether it happens now or later there is going to be a short period of time where you have to transition from your decades old technology to the newer tech.
Audio quality is compromised
Audio quality over bluetooth is just fine for the 99.9% of people that listen to music on their phone. If you are one of those that wants to hear the nuances of Miley Cyrus's voice on your phone at 8:20am in the morning whilst on the bus to work then I guess you are out of luck.
Smaller variety of accesories and at higher prices
There are more bluetooth accessories then there are wired at this point. Usually you will find bluetooth accessories come with extra features over their wired counterparts.
Just having a look on Amazon.co.uk and you can get a pair of blue tooth headphones for £4. The cheapest wired ones are about £2, both will be utterly shit.
No connector to power external speakers
Bluetooth speakers anyone ? I have a bluetooth speaker right next to my bed which is also a clock and a wireless charger (and here is the shocker this speaker doesn't need charging :-O ). When I go to bed at night I turn the light off start up my music automatically connect to the bluetooth speaker and plonk my phone on top of it and it starts wirelessly charging. Hell how about a bluetooth speaker you can have that floats in the bath whilst your phone is in your bedroom all safe and dry.
Require batteries, charging
So does your phone, perhaps you should switch back to a landline since charging some thing seems to be such a horrendous challenge. As I said I have a £20 pair of bluetooth ear bud headphones that gives me 6 - 8 hours of music from a 30 min charge.
Battery degradation ensures you'll have to buy new headphones over time
Wired headphones break you'll have to buy new headphones over time so stop buying headphones. I have some bluetooth headphones that are 2 - 3 years old and I have not noticed any measurable decrease in battery life. Obviously the cheaper the bluetooth headphones the shittier the battery just like the cheaper the wired headphones the shittier the cabling is.
No such thing such as "free wireless headphones" at trains, planes etc.
There is no such thing as "free wired headphones" at trains, planes etc either. Those shitty headphones you get for "free" were paid for by you as part of your ticket. They probably cost the airline 25p to buy and they added an extra £5 on your ticket to cover the cost of those "free" headphones.
So if they are not giving you "free" headphones perhaps you should ask for a discount on your ticket. At the very worst as wireless headphones become the norm it is entirely feasible that the airline/train company will offer you free shitty wireless headphones that are fully charged instead of offering you "free" shitty wired ones.
