Overview
The Aiwa AM-PX1 is a simple MiniDisc player released in 2003. It is definitely a sibling of the Aiwa AM-NX1, but without any recording or NetMD functionality and probably (also) Sony made. What is special about this MD player is, that there are NO! buttons on the device itself - none…except the mechanical opening switch to insert a MD and of course the compartment for the gumstick battery. MDLP is on board, as well as different EQ settings and remote connection (which is absolutely necessary for this device - more on that later). So let’s get into this rather quirky MiniDisc player! Please note that this review is based on my personal experiences and less of a technical review based on data sheet specs.

Design and Controls
The Aiwa AM-PX1 is a very compact device and made of aluminum on the front, but plastic on the back panel. There is some kind of engraving structure on the front panel and also some color design element which caught my attention towards this MD player. The silver finish is looking pretty decent in my opinion and other colors of this device available were black/anthracite and orange. The build quality is good, but similar of other units of this time it feels lightweight and plastic parts are used mainly inside the mechanism.
The PX1 runs on a standard gumstick battery, but also features a mounting screw for an AA battery sidecar as well as a dock connector. The standard Sony sidecar works on this device and I read that originally it also came with such standard Sony sidecar. As mentioned earlier there are no buttons to control playback or settings on the device itself. A remote is a must to use this device. It allows to operate the typical settings such as play/stop, skip and volume. Also the menu for EQ settings, display settings, etc. is accessible only via the remote. On that note it looks different than e.g. the Sony stick type remotes, but those may also work with the Aiwa AM-PX1. I tried the Sony RM-MC38EL, all functions work normally. It seems to be another hint that this device is probably Sony made as it was the time when Aiwa was fully acquired by Sony (end of 2002).

Connections
Connections on the Kenwood Aiwa AM-PX1 are simple as it gets: Headphone jack and remote plug. The original remote is backlit and from the user interface is the same as typical Sony ones. Track number- and name, album name, remaining play time, etc. is all easy to read. What is good to note here is that as mentioned above, if you do not have the original Aiwa remote, a Sony remote will do the job as well. Compatibility issues will likely not be a problem.

Usage and Battery Life
The Aiwa AM-PX1 is a great MD player, easy to use (with remote!) and with decent features. Good for everyday use on the go. Battery runtime is satisfying. No problems here, both on gumstick and AA sidecar.
Sound
Sound quality is good in my opinion. There are other more powerful players (from the personal preferences), but this MD has a 5mW + 5mW amp (European model probably like 4mW + 4mW, similar like the Aiwa AM-NX1). The sound is crisp, no complaints here. There are a few EQ presets like Metal, Soul, Jazz and Techno as well as a customizable EQ. It will be sufficient for most people.
For reference, I have tried the following (on-ear) headphones with the Aiwa AM-PX1:
• Koss Porta Pro
• Audio-Technica ATH-ES55
• and some simple Sony in-ears

Conclusion
So who should buy this Aiwa AM-PX1? If you look at this small device, there is nothing wrong with it. It works great, and the only downside is that a remote is definitely necessary to operate basic functions. If you can live with that, you will be happy with this little Aiwa MD.
Thanks a lot for reading. Keep rockin’ MiniDisc!
