Intro:
I like to start my review with a compliment for AIWAs customer service. From the beginning you get quick and helpful assistance giving you a positive feeling that you have chosen the right brand.
Unboxing / Inside the box:
The Arc-1 comes packed in a sturdy natural colored carton.
Whats inside the box?
- nylon headphone case
- of course a small fluffy animal
- ARC-1 headphone
- braided micro usb to cable with gold connectors and red shiny housing 1,04 m
- basic rubber 3.5mm TRS headphone cable 1,22 m
- letter to the customer
- quick start guid
- service info card
Optics & Haptics:
The black nylon headphone case is very robust and protects the phones well. The zipper is easy running and the rubber zipper handle got the red AIWA logo imprinted.
The ARC-1 looks good. Black basic well done shaped headphone. The inner red accents of the earpads with L & R imprinted in white color are stylish and fit to the companies colors. In general i have to say that i dont like colored accents so much often reminding me of the fancy Pc-gaming products.
First thing you will notice is how lightweight the ARC-1 headphone is when you grab it. The leather headband is very nicely done. Basic shape and thats good. No fancy crackling complex headband construction. The small metal AIWA logos on both sides of the headband are showing their origin. If you dont know the AIWA symbol you are probably a very young peasant. Cution is soft and comfy.
It feels to me that my ears exactly fit into the earpads. Lets see how it feels wearing the phones after an hour. I survived the hour and my ears did not get too stresses comfortwise but its no match for example to the cosy and bearish cutions of a Fidelio X2. The cutions are soft and comfy like the headband. Im not sure if the ARC-1 will fit big ears. Cutions of the Meze 99 Neo headphones come to my mind.
The length adjustment of the hangers is a bit raw. You just pull them out with a bit of gentle force and stop when you think its the correct length. The hanger will stay in this position. There are no adjustment steps. I like clicky adjustment steps like those on the new Denon AH-D models. The chosen adjustment mechanism of the Arc-1 doesnt look promising to hold its tight fit for a long time and makes the impression of wearing out sooner or later. I adjust my headphones one maybe two times and leave it then but when i adjust my headphones there is always a click and i can be sure that it is locked in place.
Operation:
The Arc-1 came fully charged and ready for action.
Very easy and intuitive handling of the functions. I just quickly scanned the quickstart pages 3 and 4 with my very own eyes and it was all clear to me. If you wake me up at night i can confidently yell out how to operate the phones. Even under mature dehydration and pain.
I test the ARC-1 headphones with the tiny Shanling M0 player.
- i press the power button located at right headphone shell. A female voice says: Power on. I blush a bit and...
- press the bluetooth button to get the female headphone ready for some pairing action.
- i nice beep appears, green & white color changing led light up.
- i turn on bluetooth aptx of the M0
- it searches
- Arc-1 found
- paired.
Hold +/- to jump forward or backward to a song works nice. Takes a little time and attention to coordinate it when you lower/raise volume (quick button pushes) but its intuitive.
Bluetooth AptX range in my apartment (doors open no disturbing walls) was approximately 8 m.
Listening experience:
You can hear that the amp of the ARC-1 gets in action. Its a very audible hiss. You hear it every time you pause the music. If the M0 get into sleep mode the ARC-1 gets silent, stays connected but as soon as you wake up the M0 the hissing is back. You cant hear that hissing playing music at normal listening levels. This is my first contact with a wireless bluetooth headphone and i did not expect to hear the amp making any noise.
I used the +/- buttons located aswell on the right side of the headphones and lowered the volume. The hissing is now unacceptable present. A totally no-go for quiet parts in the music and overall quiet listening. Im not a low volume listener so it bother me not too much in action but only knowing that theres background noise of the amp bothers me.
Lets push the + button to the max... and here he comes the BEEP, the implemented headphone eardoctor says: you shall not pass this volume!!! Thats all i get? The max volume is around my usual listening. You cant crank up the volume further. Thats too less. Some songs must be heared loud.
Sound:
Testequipment:
- Shanling M0 player
- Flac & MP3 files
Highs:
The highs are not harsh but lack sparkle and could be more detailed.
Mids:
Mids are good and complement the highs.
Bass:
The bass is elevated. It is thumping nicely and on the softer side of presentation. Another reviewer called it creamy. It can go deep and often do so but i found some music tracks where i wished for more tightness and less boominess.
Soundstage:
Soundstage is good for a closed headphone. I could hear where the sound of an instrument is coming from.
3d-effekt / Spaciness:
If you go to the specs on the AIWA homepage you will find the words „technology: surround“. Dont be scared about your stereo experience. The Arc-1 got no elevated space. It sounds right. You will not get pumped into heavy surround sound 3d effected landscapes.
Voices:
High female voices wont pierce your eardrums. This phones are made for a non fatiguing listening experience. Voices are not pushed into your face and go along with mids and highs.
Overall presentation:
Bass focused. Can sometimes be too much. The highs are not fatiguing. The mids go well with the highs. Its a headphone for long listening sessions. You wont hear the crispiest sparkling highs and not the tightest mids but the frequencies get along with each other very well.
Conclusion:
The Arc-1 in its current state is not for me. The hissing of the build in amp is too audible and signature and some haptics can use improvement. The max volume is too low.
What can you do to make the Arc-1 better?:
- make it louder
- make the earcups a bit bigger
- satisfying clickable headband adjustment
- tame the lows a bit, convert some of the softness into tight striking tones
*** Note from the author: ***
This review reflects my personal experience with the Arc-1. Previous reviewers are blown away making you think buying a 1000 $ worth headphone. I show what i think is not good and how it could be refined. I appreciate if you have a different opinion and think: "what the hell phony..." this is not true. Leave me a message. Theres a promising Arc-1 product out there and its worth to be improved.
