The ZSA are dual driver in-ear headphones with a detachable cord. There&#039;s no fancy features like volume control, skip controls, or microphone, but at US$23 that&#039;s expected. You can buy bluetooth cord with volume and skip controls for about US$9.<br />
<br />
The earphones are surprisingly good for $23. I find the high frequencies too strong and a little shrill in most cases, particularly with jazz, but not so bad it&#039;s a deal breaker - you might be able to reduce that with an equaliser. In most cases they&#039;re fairly well balanced, with good detail, good vocal clarify, and good bass. Jazz music isn&#039;t a strength because of the shrill highs.<br />
<br />
The earphones come with a wire that goes over the top of your ear, to try to support them. This is necessary as they&#039;re quite heavy metal earphones. I had trouble getting a good seal, and I wouldn&#039;t recommend them at all for use while walking, running or at the gym as they&#039;ll probably lose their seal, move around, and get annoying. Comfort and portability are compromised as a result of the weight.<br />
<br />
I compare all headphones with our Audzee LCD2 headphones. These are open circumaural headphones that cost US$1000 and are just awesome. It doesn&#039;t matter what you listen to with the LCD2, it sounds good, and makes you want to listen to more. The ZSA doesn&#039;t come close to the LCD2, but given the LCD costs 43 times more than the ZSA that&#039;s not a big surprise.<br />
<br />
Here&#039;s some comments on my standard test tracks.<br />
<br />
Cinderella Man / Eminem<br />
Bass is average strength and fairly low, but not super low or super strong. Highs are fairly good, vocals good.<br />
<br />
Sinners Prayer / BB King / Ray Chalres<br />
Reasonably well balanced. Good mix of highs and lows. Highs a little shrill at times, but good clarity.<br />
<br />
I Love Being Here With You / Diana Krall<br />
The cymbals are clear but a bit too loud - they overwhelm the track including vocals. Vocals sound pretty good. Bass is present and appropriate.<br />
<br />
The Chokin Kind / Joss Stone<br />
The highs overwhelm again. Shrill and too loud. Bass is a bit weak. Vocals are good.<br />
<br />
February Song / Josh Groban<br />
Highs are bit strong, bass a bit weak. Vocals about right.<br />
<br />
I Believe It To My Soul / Joss Stone<br />
Cymbals a little too shrill / loud. Vocals good. Bass a little weak.<br />
<br />
Voices of Trance April 2012 (electronic)<br />
Quite good. Represents the spectrum quite well. Highs maybe a little strong, but all in all well balanced.<br />
<br />
In conclusion I think these are good headphones for they money, so long as you can tolerate highs that are a bit sharp at times.<br />
<br />
Test setup: 128 - 320kbps mp3 files, fed from Bluetooth on a Huawei P9 running Stellio music player on Android 6. No equalization is used.<br />
