5.0 out of 5 stars Great Portable Speakers that pack easy, October 10, 2006

By	M. J OBRIEN (Oak Point, TX United States) - See all my reviews (REAL NAME)

This review is from: Logitech® mm28 Portable Speakers (Electronics)

I have owned many portable speakers...none have the sound quality that these have given their size. They actually fit perfectly in the top pocket of most rollaboard luggage...solid flat case. The reason they sound so good is that they use a planar speaker design much like Magneplanar high end audiophile speakers or Monsoon computer speakers. Low mass means fast accurate sound reproduction with little energy. One price though is the unrealistic bass many like to hear is not there but the bass that is natural is and it's reproduction is very accurate...better than speakers 10 times the size because of planar design.

I own a pair of Magnaplanars and a 2 sets of Monsoons and always wanted something I could carry the size and shape of book. This is it.

Battery time is unbelieveable. I have yet to run them down on even a 3 day trip. I purchased rechargeable batteries from SAMs that are enegizers...wish I had bought the lithiums...20bucks and you have a charger and batteries that will run these about 200 hours!

What is wrong...the cord, I almost lowered it a star for this reason alone. It stows nicely but it is much to short. The stow design would have supported another 1 or 2 foot of cord which it dearly needs. I like to use these with my laptop but using the keyboard with them connected is really difficult. You need to buy an extension cord to keep your frustrations down.

Another greater feature is the blue led on-off led on the top. Bright enough to know it is on but not a bother in the dark. The automatic turnoff feature in the absence of sound for a few minutes is also nice.

Volume is loud for a speaker this size and I seldom turn it up all the way. I use these in hotel rooms and they are loud enough that I do not turn them up all the way lest I bother my neighbors. They will distort when turned up when high bass is present and they are overloaded. This is usually a problem with the batteries...current supply. Use rechargeables, particularly lithium, and you will get more out of them since the current available is higher. Same goes for any electronics.

I paid $80 for mine and here at Amazon I now see them for almost half that price....may buy another pair for spares!

4.0 out of 5 stars Logitech powered speaker, June 25, 2006

By	Reviewer - See all my reviews

This review is from: Logitech® mm28 Portable Speakers (Electronics)

The speakers sound very good even at high volumes. This is a very good addition to mp3 players. I use it connected to my pocket pc to listen to internet radio stations and podcasts.

There is a significant "wow" factor with the design.

One caution however, there is no volume control on the speaker. The volume must be controlled at the source which can be inconvenient at times.

2.0 out of 5 stars Sound great, but beware of the auto shut-off feature .., October 8, 2007

By	jbf (CT, United States) - See all my reviews

This review is from: Logitech® mm28 Portable Speakers (Electronics)

I got these to upgrade my laptop speakers while in its docking station. The good news is they sound great. The bad news is they were designed with an auto power-down feature to prolong battery life. Even though mine are plugged into the AC power adapter 100% of the time, they shut down without a music signal running thru them. I sometimes play classical music in the office and even have had them shut down in quiet passages of some pieces, or even between songs. This is not documented anywhere in Logitech's instructions or packaging, but can be verified thru their tech support.

They are probably perfect for their intended use as a battery powered portable speaker system, but under AC power with a permenent install, they have been a disappointment.
