Boostaroo T613-BNC

Great Product

Works great for boosting your sound, especially if its a quiet recording.

Great product! Exactly what I was looking for!!!

I bought this product as a gift for my father who loves to jog, but has a hard time hearing his tunes on his MP3. Even at full volume, he still could barely hear the music. The Boostaroo made short work of this problem! It's small enough that it can fit easily into his pocket while he runs and now he can hear all his favorite songs at full volume. GREAT PRODUCT!!! Thanks Boostaroo : )

works as advertised

Does increase the audio level, not sure it's doubled, but that's had to tell and subjective. Wish it had a level control and also amplified to a higher gain 6db would have been nice. But, it does what it was advertised to do so it gets a thumbs up from me.

Good buy

I use this product to amplify the signal from my MP3 player to feed it into the stereo system. It works well for that purpose. The amplification Boostaroo provides is fixed. I wish it provides a bit more amplification.

A great audio sound booster

I bought this product to enhance my mp3 players audio and I am not disappointed with it . I would recommend this product to anyone looking to boost their audio sound. I'm completely happy with my purchase.

bosteroo T613 total joke do not buy

the T613 requires an old-configuration alkaline battery to be the lead battery or it will not work. the trailing battery can be any kind of battery. the old-config alkalines are no longer manufactured. new alkalines do not work

the port through which the output signal is circular. this means it can twist 180 degrees and eventually becomes flaky and then dies off altogether.

the translucent plastic piece that snaps over the batteries loses its grip after 3 months and has to be held on by a rubber band

it's obsolete and no longer in stock

Amazing Invention

Truly boosts volume in my iPOD touch to 2x the level. Outstanding sound quality. Everything I hoped for in a portable volume booster.

Boostaroo

3rd one I own and bought another for my son. Had the first one for years and the cord eventually kinked so I replaced it and have one for at home and one I travel with. Does everything it claims to do!

Great product

We got this device to use for 2 headphones out of a 14" laptop on air flights. The amplification was clear and significant - just what we wanted. I am very glad we purchased it.

headphones amplifier

Amplifies LINE-OUT audio enabling use of any headphones. There are 3 outputs for 3 listeners. Since the volume level from LINE-OUT is independent from the standard volume control, I can watch TV with its volume turned OFF while comfortably listening to the audio stream via headphones. It operates on two AA batteries, which eliminate the 60 Hz noise from the power line. Only most expensive amplifiers can be so quiet. The audio quality and the dynamic range are great. The power consumption from the batteries is insignificant. For some headphones (Apple, active noise canceling) the output volume level may be too high. Some output control would be beneficial. Overall it is great product, very competitively priced.
