Wave IEM Review: Soundbrenner's In-Ear Monitor for Musicians

Overview

If you've spent any time scrolling through Instagram or Facebook lately, chances are you've seen the marketing campaigns for Soundbrenner's Wave in-ear monitors. The targeted ads are everywhere—promising professional-grade monitoring at a fraction of the typical cost, with testimonials from touring musicians and pristine studio shots that make these $99 IEMs look like they belong in a much higher price bracket. As someone who's tested lots of music equipment over the years, I'll admit the persistent social media presence piqued my curiosity enough to warrant a proper evaluation.

The Hong Kong-based music company has built their reputation primarily around metronomes and practice tools, making their entry into the competitive IEM market particularly interesting. The Wave represents their first serious foray into professional audio monitoring, and the aggressive marketing suggests they're confident in the product's capabilities. After testing across various musical scenarios, here's what I discovered about whether the Soundbrenner Wave lives up to the social media hype.

Sound Quality

The Soundbrenner Wave delivers a balanced sound signature that prioritizes musical clarity over flashy frequency response curves. Built around dual 10mm dynamic drivers with dual-magnet architecture, these monitors produce a sound that's notably neutral—avoiding the hyped treble or boosted bass response that many budget IEMs have.

The frequency response spans the full 20Hz-20kHz range with particular strength in the midrange frequencies where vocals and lead instruments live. The Wave's bass does come in a little bit low, which may have some musicians compensating with boosted bass in their personal mix, but the neutral sound signature does ensure that your mix not be muddied up live. The treble extends cleanly without harshness, making these suitable for extended monitoring sessions without fatigue.

What stands out most is the Wave's ability to maintain clarity at higher volumes—crucial for stage monitoring where you're competing against acoustic drums and amplified instruments. These in-ears excel in their intended role: giving musicians an accurate representation of their performance and mix during live situations.

Build Quality

Soundbrenner has clearly prioritized durability in the Wave's construction. The housings are lightweight yet robust, weighing just 9 grams per earpiece—a significant advantage during long performance sessions. The ergonomic shell design follows the natural contours of the ear, distributing weight evenly to minimize pressure points.

The detachable braided cable is a standout feature in this price range. At 1.5 meters, it provides adequate length for stage use while the braided sheathing resists tangling and wear. The connection points feel secure with positive engagement—critical for live performance reliability.

Included accessories demonstrate thoughtful engineering: six pairs of ear tips in both silicone and memory foam materials ensure proper fit across different ear anatomies. The memory foam tips contribute significantly to the advertised 36dB noise isolation, while silicone options provide a durable option for daily use.

The carrying case is practical—a hard shell that protects during transport without adding unnecessary bulk to a gig bag.

One feature that many In-Ear Monitors offer that the Wave does not is a cable slack adjuster to change the point of tension to a more comfortable position.

Value for Your Money

At $99 USD, the Soundbrenner Wave occupies a sweet spot in the IEM market. This price point typically forces compromises—either sound quality suffers, build quality lacks, or both. The Wave manages to deliver great performance in both areas.

The inclusion of premium features like detachable cables and comprehensive ear tip selection at this price point is noteworthy. Many competitors charge significantly more for similar construction quality, or omit these features entirely to hit lower price targets.

For musicians, the Wave represents an enticing value proposition: professional-grade monitoring capabilities without the investment required for custom-molded solutions or high-end universal designs. The durability and replaceable cable mean these can withstand the rigors of regular gigging while maintaining their performance.

How It Competes

The sub-$150 IEM market is intensely competitive, with established players like Shure, Audio-Technica, and numerous Chinese manufacturers vying for market share.

Against the Shure SE215 ($110), the Wave offers a more balanced and bright sound signature, though the Shure 215's provides a more pronounced bass response that may appeal to some genres, but can muddy complex arrangements.

Compared to KZ and other Chi-Fi options in this price range, the Wave sacrifices some technical specifications (many Chi-Fi models boast multiple balanced armatures) for better overall coherence and reliability. The Wave's tuning and quality control tend to provide a more predictable performance.

The Audio-Technica ATH-E40 ($99) offers similar positioning but with a slightly brighter signature that can become fatiguing. The Wave's more neutral approach and superior comfort give it an edge for extended use.

Where the Wave truly differentiates itself is in the complete package—the combination of sound quality, build, accessories, and brand support creates value that exceeds the sum of its parts.

Closing Thoughts

The Soundbrenner Wave succeeds by focusing on what matters most to working musicians: reliable performance, comfortable fit, and honest sound reproduction. Rather than chasing specification sheet victories or flashy frequency response graphs, Soundbrenner has created a tool that serves its intended purpose effectively.

These monitors provide clear, balanced monitoring that lets musicians focus on their performance rather than fighting their gear.

For the target market—gigging musicians, music students, and performers seeking an upgrade from generic earphones—the Wave represents a sensible investment. The combination of professional features, roadworthy construction, and competitive pricing makes these easy to recommend for most musical applications.

The Wave positions Soundbrenner as a serious player in the pro audio space, extending their reputation beyond metronomes into products that directly impact musical performance. For a first-generation IEM effort, it's an impressive debut that suggests promising developments ahead.
