I have posted a more detailed review on my blog with hi resolution pictures. http://blog.hyperexpert.com/audio-technica-at-pha50bt-first-impressions-and-review/
I stumbled upon Audio Technica’s AT-PHA50BT little device that seems to offer exactly what I need. Even though this device was only released in Japan, there are plenty of sellers on Amazon and eBay that are willing to ship it to the US. At the time of writing this review, there weren’t any online reviews that I could find about this product (except for the very few Japanese ones), I decided to write this review hoping that it might help somebody else on the same boat. I decided to try my luck with this little device and let me tell you, I am not disappointed at all.
When I opened the box, I was really surprised by how small this device is, very tiny. Build quality is really good and solid. Exactly what you would expect from a reputable company like Audio Technica. The volume rocker clicks in place when you turn the volume up or down. It does not make any noise, but it just has a little snap to it to keep the rocker in place instead of freely sliding left or right.
In the box, you will also find a small micro USB cable for charging, a small clip case, and the user manual and a device registration paper.
Looking at the AMP, the power/lock button and a USB charging port are on one side. Four other buttons, effect/call, play/pause, skip forward, skip backward are on the other side. Everything is clearly labeled in English. The front LCD screen is very nice and bright. You can see the battery level of the device, volume level, call history, and icons that show up at the top of the technology being supported with the device it is connected to. In my case, I had it synced with my iPhone 6 so it showed me HFP, A2DP, AURCP, PBAP. You also can see on the screen what is currently playing on the phone, band and song info. Obviously, everything on the screen is in English. The device supports showing names in Japanese. I haven’t had the chance to try that, let alone understanding anything.
Sound Quality
I purchased this little device not to improve my sound quality. I have a pretty good home setup that I am happy with. I only wanted something more convenient for on the go. I was going to be pretty happy and satisfied if it had the exact same quality as plugging in the headphones to the phone directly. Except, having this now I can clip it to my shirt or put it in my pocket while using my phone freely.
When connected to my iPhone and sending music through the AMP, and since the iPhone also supports AAC, the AMP displays “AAC” on it’s screen. I am not sure if it will change the sound quality if paired with a device that does not support AAC or aptX. I also do not have any aptX device at the moment that I could try the AMP with.
Keeping in mind, I only have a small library of music stored on my iPhone. I mainly stream my music from iTunes Radio and xbox Music. When I first tried it, I couldn’t believe what I was hearing. I instantly became very happy. I kept switching back and forth between the AMP and phone and I could not tell a single difference. Could it be because of taking advantage of the AAC feature?
I mainly listen to modern and classic Rock and some classical music. Classical music sounded slightly little more crisp when connecting to the phone directly without using the AMP. I had to switch back and forth few times to be able to tell a difference. Then finally deciding that connecting to the phone has a slight more crisp sound to it. It’s not big, maybe only better by 5% when connected to the phone and not using the AMP. Definitely not a deal breaker. Also, I really didn’t notice the difference at first and took me many tries back and forth to be able to tell.
The AMP also has built-in sound effects engine. It uses AM3D that has four modes “Flat” which is the normal/pass-through mode without making any changes to the sound, Acoustic, Vocal Boost, Bass Boost, and Virtual Surround. I don’t like any of the sound effects and just keep it on Flat the whole time.
Overall, sound quality is really as good as connecting the headphones to the phone directly using AAC. I would love to try aptX one day and see if that makes any difference when listening to classical music over AAC. Will update this review if that happens.
Dislikes
One thing I really dislike is having two independent volume levels. The AMP does not control the phone volume. The AMP has its own volume and when turning the volume up or down, it only changes its own volume and not the phone. Also, there is no way to see the AMP volume level BEFORE starting to play your music. Not sure who came up with that idea.
Final Thoughts
I am very happy with this purchase. I could not have asked for more out of this little device. Solid build quality, lightweight (only about 29 grams), lots of features, very small and easy to commute with, and sound quality is as good as plugging my headphones to the phone directly. Charging the battery barely takes 3 hours and play time is about 8 hours. I definitely recommend this if you are looking for a small adapter for the purpose of making your wired headphones wireless. The AMP also has built-in microphone for making phone calls if your headphones do not have a mic.
