Symphonized NRG 3.0 Review

by David Wright | Last Updated on November 26, 2020

Symphonized NRG is popular among enthusiasts fond of wired in-ear headphones with aesthetic appeal and compelling design. However, technical features are also important, and this Symphonized NRG 3.0 review will walk you through the major considerations before you make the final decision.

Symphonized NRG 3.0 is the 3rd version of the product line. Let us see what kind of upgrades this latest model comes with.

Symphonized NRG 3.0 Overview

Product Headphones
Type In-Ear / Wired
Enclosure Closed-Back
Microphone Yes

Since the Symphonized NRG 3.0 is a budget headphones, it is unfair to compare its sound quality with the high-end and more expensive models.

The design and material of the NRG 3.0 are decent but weighs slightly more than most of the wired headphones. The reason is that the wire is a bit thicker, and on occasion, you might notice the drag against your shirt or jacket. However, the headphones are stable when running and easy to carry.

The Symphonized NRG 3.0 is a passive headphone and blocks most of the ambient noise.

Items in the Box

  • Symphonized NRG 3.0 In-Ear Headphones
  • Six Earbuds Tips (different sizes)
  • User Manual
  • Pouch


Symphonized NRG 3.0 earbuds with eartips and case


Wooden earbuds are the distinction of the Symphonized NRG, and the 3.0 version also features a straightforward design with a variety of color options, including:

  • Dark Wood / Black & Gray Theme
  • Dark Wood / Red & Gray Theme
  • Medium Dark Wood / Orange & Gray Theme
  • Medium Dark Wood / Blue & Gray
  • Medium Dark Wood / Purple a& Gray Theme
  • Light Wood / Yellow & Gray Theme

The cable is rubberized and features the 2-color theme. However, its feel and look are far from premium.


The Symphonized NRG 3.0 headphones weigh 0.03 lbs. The in-ear fit is comfortable, and the additional six ear-tips in the pouch let you select the most suitable pair for optimal fit.

The material of these tips is flexible, but they don’t feature foam. The feel is more like most of the conventional in-ear headphones. The designers have made a good job to keep things simple yet effective.


The in-line controls are easy to access and use, and the buttons’ tactical feedback isn’t bad either. Symphonized NRG 3.0 in-line remote supports volume, music controls, and calls. The microphone controller is missing, though.

No talk-through, no noise cancelation, and no channel mixing. The buttons’ size seems slightly smaller than usual, but the spacing between the buttons makes it easy to identify them without even looking at the remote.


The LxWxH dimensions of the Symphonized NRG 3.0 are 1.7” x 1.6” x 1”, and they occupy a volume of 2.7 Cubic Inches. Portability of the Symphonized NRG 3.0 in-ear headphones is easy, and their pouch makes it more efficient.

The downside is that this pouch doesn’t offer much protection. The pouch’s only purpose seems to keep the headphones from tangling with something else inside the pocket or bag.


The durability of the Symphonized NRG 3.0 is decent. The rubberized cables are relatively thicker than most of the wired headphones. The wooden earbuds don’t easily break or crack after dropping on the solid floor.

The remote control has a nice and cool fit, and apparently, nothing looks out of the place.

Since you don’t usually find uni-body earbuds, some parts’ loosening is obvious after a few months of use. Expensive headphones often come with detachable lines, but you can’t expect that feature in a budget in-ear headphone. To me, Symphonized NRG 3.0 build quality is pretty good overall.


One of the most important considerations of the Symphonized NRG 3.0 is stability when running or walking. The tips remain comfortable even if the earbuds slip a bit deeper inside the ear, and usually, they do. Dislodging the earbuds amidst casual listening becomes slightly tough, but it doesn’t hurt.

The stability during running and walking is better than most of the in-ear headphones. Symphonized NRG 3.0 is missing stability tips or clips, which means the usual intentional tug on the cable will pull the earbud out.


0.11 dB Average Standard Deviation suggests excellent Frequency Response Consistency. With a nice fit and proper seal (selection of the right ear tip), you can ensure outstanding performance every time.

Brass Range Performance is below average. The response feels flat, and you can easily notice the impact of heavier bass. The high-bass also features a somewhat annoying additional bump, which optimizes boominess.

The Mid-Range Performance of the Symphonized NRG 3.0 is good. The continuation of the high-bass bump is almost 3dB (overemphasis). Somewhat muddy sound is the feature of these headphones at Hyper-Low Mid. The Mid and High-Mid ranges push back leads or vocals more than you’d like.

Talking about the Treble Accuracy, the performance is poor here. Over 5dB underemphasis at Low-Treble feels slightly out of the place as it negatively impacts vocals. There is inconsistency at high-treble as well. The overall sound feels bass-heavy and dark.

Noise Isolation

Symphonized NRG 3.0 headphones are good at noise isolation. Though you don’t get an active noise cancellation feature with this model. The reduction of 5dB, 19dB, and over 40 dB (Bass-Range, Mid-Range, and Treble Range, respectively) better than most budget headphones without active noise cancellation.


21.21 dB at 1 foot is excellent in terms of leakage of any headphone. It is even quieter than some expensive headphones.

At the Bass-Range and Mids, the leakage is closer to none. Slight leakage is audible at Treble-Range.


Symphonized NRG 3.0 has an in-line microphone that supports analog audio. It is not detachable. The quality of audio input is good in quiet surroundings; however, if you want to record something for a webinar or a YouTube video, you will have to go for a noise-cancellation microphone.


I can conclude this review with smiley lips since this model’s features are better than what I usually expect from budget headphones. However, if you are a critical and music-sensitive geek, you may not get the sound quality you are used to if you mostly go for expensive and high-end headphones. But I think that Symphonized NRG 3.0 is among the best in-ear budget headphones available currently.
