After 4 years of hard use I finally have to realize that my E5 is dead. Unfortunately it is the battery in the given one and even with usb cable connected to it directly from computer or mobile so I can not start it.
Was it worth it? Yes, I think so. The connectivity is much better than most other small DAC / AMPs on the market. The sound quality is better than the price indicates. The built-in microphone works very well. Because it only lasted for 4 years, I lower one star. But still well worth the money.
After using my e5 almost daily for over three years, it still holds an incredibly high standard. However, the battery life has decreased slightly - about 4 hours on bluetooth and has tended to be slightly heated when charging.
There have been many and welcome updates to the built-in software that have increased the possibilities with this external sound card.
In my opinion works best with usb cable for PC, bluetooth for phone and optical cable for game console. Definitely worth the price and for most a better alternative than the newer g6.
Old review from 2016:
Have used this portable dac / amp for about 5 months and very pleasantly surprised. E5 has all the connectivity I need and provides a sound quality that is much better, even for "low quality" sound, such as from Spotify or google play music, no matter what portable audio source I use. Unfortunately, the E5 has an annoying voice prompt when connecting additional audio sources - wish it could be turned off.
Have not used really good handsets, but even with cheap handsets it will be a big boost in the sound. (Mostly used aiaiai tma-1 studio and audio technica m50x)
- The price, a lot of sound for little money
- Connectivity (usb, bluetooth, line-in, toslink)
- Built-in microphone
- Good battery life
- Double headphone outputs
- Something bulky / thick when you put it together with your phone
- Requires control app - desirable with screen on E5
Recommended to anyone who wants to get more out of their portable sound.
