I own all 3, because of the ebay user: Nocando01
Who gave me the E1/3 and the Boostaroo for free :)!
Thank you :D!
Its been a long time since iv'e been on Head-fi, and i always intended to make this comparison for you guys.
Just forgot to do so, and it has been, long overdue.
So, i will give you an easy to read PRO and CON for each of the amplifiers :)
Fii0 E5:
Pro:
-Light
-Rechargeable
-Doesn't use your battery
-Can be used with any device, as it is a 3.5mm in/out
-Good bass boost function
-10hrs battery life, longer than my iPod touch could do
-Easy functionalities with controls
-ON/OFF switch
-£15, which is VERY cheap
Cons:
-Extra wiring
-You won't ever get it off :P!
Video review:
Fii0 E1:
Pro:
-Light
-Doesn't use an EXTRA battery, no need to worry about recharging the amplifier unit, plug and play
-Better controls: Play, pause, next, previous, volume up and down.
-£16, which is VERY cheap, especially for an LOD as well
-Nice clarity/cleaner sound
-LOD included
Cons:
-Can ONLY be used with an iPod
-Drains your iPod battery
-Bit too long in term of wiring, quite a lot of wiring in your pockets
Video review:
Fii0 E3:
Pro:
-Extremely cheap for an extra sound gain: £7
-Boosts your sound
-Uses AAA battery
-No recharging
-No ON/OFF, switches off on it's own when not used
-Doesn't use any battery but for your AAA battery
Cons:
-Uses AAA battery
-No controls
-No ON/OFF, switches off on it's own when not used
-Bulky
-Distorts at higher volumes, whereas the e5/e1 won't do
Video review:
Personal input:
-If you want bass, go for the E5.
-If you have an iPod and won't mind a LITTLE bass "loss" in comparison to the E5, get the E1
-If you have no money or want to try it out, get the E3
I personally think the E3 is a waste of money, and the E1 is limited in use, in terms of:
-I can only use it for my iPod, if i don't have an iPod (Hopefully selling my 64GB touch soon) then its useless
Out of all the 3, the E5 is the best. That's my opinion.
I bought the E5 first and made the best decision.
I made a review and got sent the E1/3 for free. Made a review, and was happy to compare and contrast, but still used the E5.
Final comparison video (all-in-one):
Hope that helps you guys :)
Enjoy!
