Monster Cable Turbine Pro & i.Fuzen iPhone Case

Battery is great, better then my iPhone

The case is pretty simple, but it's low profile. A significant plus when stepping over from the Trident case. That thing was a brick in my pocket. I think my phone could have survived nuclear warfare. I just wanted something to keep it nice, and that certainly did. My biggest complaint was that when I would pull my phone out of my pocket, it would pull everything else out too. The second time I had someone behind me tell me I dropped something, I decided I might need to start looking for something a little smaller. This has been a good choice. Almost the same price, but this has a battery that over doubles my iPhone's life. I am on the maps app a lot, and texting too, so this has been great.

Good at first, then it stop working after 5 monthes

I bought the i.Fuzen HP-1 to help protect my I-phone 4s, extend the battery life, to listen to music through the built in amplifier but mainly to use in my cars sound system.

I like to say that I treated this item really good and never dropped the item. The i.Fuzen HP-1 case worked fine for the first 3 months and then progressively it did not hold the charge as long as when I first got the case. The i.Fuzen HP-1 case stopped working properly with the I-phone 4s and as time passIi could not listen to my music through the i-phone anymore. Eventually I could not charge the case any more and the case just died.

I think the sound quality is good. I compared the sound quality with the I-phone 4s and I found that the sound of the i.Fuzen HP-1 case has a little more bass than the I-phone 4s, but I can not really say it is a better sound. The case does have a little different sound quality with more pronounced bass and mids and highs. I listened to the case using I-phone's white headset to make the listening test. This test also confirmed that the case's battery did not last as long as the i-phone 4s when listening to music through the case's built in amplifier.

In addition I tested the sound of the case on my car 2003 GMC ENVOY with the after market sound system installed. The headunit is JVC KW-AVX810, door speakers are Infinity Kappa 62.9i two ways, a pair of Alpine SWR-1223D subs and two Alpine amps PDX-F4 for the mids/highs and PDX-1.600 for the subs. Well the case sounds good with higher bass tones than the I-phone 4s. I found that the case sounds good through my cars system , but I also confirmed that the sound of the I-phone 4s is also really good with a little less bass which gave me more control to shape the sound the way I wanted to listen to my music depending on the volume I decide to choose.


In conclusion I feel that the higher tones of bass, mids/highs produced by the i.Fuzen HP-1 case is better suited for a headset or a system that can not produced enough bass or quality sound
I can not recommend the i.Fuzen HP-1 case since durability was short and I will be returning the item.

Might be defective

At first the battery worked well , after 2 months I find myself charging
It more . Only getting 2-3 refill charges . May need to return but I like protective casing and solidness on it .

Don't do it!

I bought this battery pack cover bc my phone was discharging rapidly, so I needed more power to get thru a day. I used to have a Mophie and loved it, but after a few drops it needed replacement. The Fuzen case was half as much, so decided to try it. BIG MISTAKE. The phone is not protected at all...it sits too high and the edges aren't wrapped at all. Plus the design is poor for the user...can't even charge from an outlet, have to us a laptop.

Does what it should.

I purchased this to extend my phones battery usage. It does just that. It will charge your phone but to what % depends on your usage. For me with some usage like txt and calling it will charge my phone from 10% up to 70%. With non it will charge it to 100%. I like it and would buy another.

Awesome!

Had everything I was looking for! The case isn't TOO bulky either so that's definitely a plus for me

Awesome for the price

Wanted a simple fix for my battery dying dying on my 4S when I have no place to charge. This fixed the issue specially when I'm on a family trip to Disneyland, with having this case my phones life last the whole day at the park. If you don't want to spend an arm a leg for the one they sell in the Apple store and still get a awesome case that actually helps your phone this is the product.

EXCELLENT Unit! Very Well Designed!

This is an exceptional piece. It has a built in headphone amplifier with the Case and the external battery. The battery is a must have! And the price is certainly right. But the headphone amp is icing on the cake! great unit and an even better price.

I love it

It's nice having this case to reduce the amount of times I have to recharge my iPhone but I really bought it because of the amplifier. I have another portable amplifier that I was tired of carrying in my pocket because it is not that convenient so I decided to try this case and........MAN O MAN is this thing awesome. The sound quality is "audiophile quality"........for a portable piece. You will be able to play your music or whatever louder but I really like the amp because the sound is full (strong bass, clear vice, and highs not piercing) at lower volumes. Definitely worth the money in my opinion.

Its a STEAL!!!

i got this because of the price, and its got a good battery life on it. but i was most impressed with the amplifier in it. i was planning on getting a little amp for my headphones like the fiio or boostaroo, but this was more then sufficient. i have the klipsch reference earbuds, and they are good headphones to begin with. now i understand all the reviews people were writing about them. the sound has really filled out, and there is nothing lacking. the bass is far more present than i had anticipated from the tiny little port they are equipped with. even when i tried using the regular iphone headphones..... WOW. no need for the portable headphone amp now.

oh yea, and the battery is great also. i went 4 days straight without a single charge. and thats with regular usage. pandora would usually drain my battery every day, but now its like i got three batteries.

overall, this was far better than the other battery cases i have tried before. most of them were just another poorly manufactured piece out of china, but this one truly did everything that it said it would. and they seriously under sold me on the headphone amp. i would have paid that price just for the clean, full, sound out of my headphones, mix that in with a battery and case, SOLD!
