Audio Performance

As stated in the introduction, as well as their name, the 1MORE Triple Driver BT In-Ears use three separate speaker drivers to produce sound. A "standard" dynamic driver equipped with a metal composite diaphragm is combined with a pair of balanced armatures (think tweeters). On the wireless side of things, 1MORE used a Bluetooth 4.2 chip, which supports SBC, AAC (iOS devices), and LDAC audio codecs, with the latter currently being the best way of transfering audio via Bluetooth. LDAC has a bandwidth of up to 990 kbps and can be used to decode 24-bit/96 kHz audio files. In order for you to be able to use it, your source (smartphone) needs to support LDAC as well. The codec was developed by Sony, so all of their Xperia smartphones support it, along with some higher-end Samsung devices (i.e., Galaxy S8 and S9), Xiaomi devices based on Android 8.0 and newer, the Essential Phone, Razer Phone… the list goes on. Apple's phones don't support LDAC, but 1MORE took that into consideration—your iPhone or iPad will use the AAC codec when combined with the Triple Driver BT In-Ears. Its bandwidth is 250 kbps.

In case you have a device that doesn't support LDAC or AAC, it will use the SBC codec, which is universally supported by all Bluetooth devices. It offers a maximum transfer rate of 320 kbps, which is still good enough to enjoy streamed music on the go. You won't be able to fully utilize your Tidal HiFi or Deezer HiFi subscription as lossless files can't be handled by SBC, but I'm certainly not one of those people who'll try to convince you that there's a vast difference in sound quality between FLAC files and lossy 320 kbps MP3s/OGGs. If anything, I'd much sooner tell you that most people won't be able to make a distinction between them if subjected to a blind test. Yes, the difference exists, and it can easily be picked up on a resolving hi-fi system/headphones/studio monitors, but it simply isn't something you'll care about while listening to your favorite tunes on the go. Still, it would be nice if 1MORE included aptX HD codec support (576 kbps bandwidth, 24-bit/48 kHz file support) since aptX HD is widely adopted on newer smartphones—more so than the LDAC codec.

Back to the audio performance of the 1MORE Triple Driver BT In-Ears. I'd describe the sound signature of these headphones as full, detailed and very, very energetic and fun. They're bassy to the point of being slightly boomy in the lowest part of the bass range, but with a clean and smooth mid-range and well-controlled highs that are quite tame and never piercing. If you had a chance to try the wired version of the Triple Driver In-Ears, the wireless model is sonically similar, but with a slightly stronger emphasis on the bass, which is exactly what many users wanted. In case you'll find the boominess of the bass too excessive for your liking, it's worth mentioning that it's possible to remedy it to some extent by replacing the ear tips with a pair that doesn't seal as tightly. It works the other way around as well—you can increase the perceived volume and scale of the bass by pushing the ear pieces deeper into your ear canals.

The 1MORE Triple Driver BT In-Ears also fare well with stereo imaging and instrumental separation. They're capable of creating an impression of a much grander sound stage than you'd ever think you could get from a pair of in-ear headphones. All of this happens without the vocals ever sounding drowned out by the music. If anything, the vocals are pushed forward and placed "close" to the ears, which makes them sound quite intimate. Simply put, the 1MORE Triple Driver BT In-Ears are great-sounding wireless headphones. In terms of sound quality, 1MORE knocked it out of the park this time around.


Talk Talk's "The Rainbow" is a song from their fourth album Spirit of Eden, recorded back in 1987 and 1988. Even though the album bombed commercially, most likely due to the fact that the band made a radical change to their sound, which alienated fans and critics alike, I absolutely love it for its experimental nature and the tranquil atmosphere it manages to create. In many ways, Spirit of Eden was ahead of its time. The Rainbow is a nine-minute song the album opens with. It has a very slow build-up; it takes almost three minutes before the rhythm section starts playing, which many perceive as the "real" start of the song. During the almost-three-minute intro and throughout the song, you can hear an impressive number of instruments, including those that can be a handful for any pair of headphones or speakers, such as the Variophon, a trumpet and a violin. Because of that, and because of its varying dynamics, this song is a great test of overall sound quality for whatever you're listening it on. On the 1MORE Triple Driver BT In-Ears, the trumpet, Variophon, and harmonica sound clean and detailed without becoming shrill and piercing, even when listened at maximum volume and during particularly difficult parts, such as the one around the 7:15 mark, when the Variophon really lets loose. The piano sounds weighty, the rhythm section gives the song a nice fullness, warmth and flow, and Mark Hollis's subtle, dreamy voice remains distinctive.


Yosi Horikawa's "Letter" is a go-to song for many reviewers who dabble in headphones and speakers. It's easy to understand why—it opens with a sample of rustling papers and a pencil scribbling on them, contrasted by soft synths that establish a beat that plays throughout the song. The sound of scribbling pencil constantly moves from left to right, and you should be able to hear that clearly if your headphones/speakers are good with stereo imaging. The 1MORE Triple Driver BT In-Ears pass this test with flying colors. The movement of the pencil sample can easily be heard, with the whole song sounding massive once the intro spills into the main theme.


Icelandic musicians Ólafur Arnalds and Arnór Dan recorded a song "Take My Leave of You", heavily featured in ITV's excellent crime drama Broadchurch. It consists of a beautiful, weighty piano theme accompanied by dramatic strings of varying depths. In more complex parts of the song, such as the one around the one-minute mark, some finer details in the low-end get lost on the 1MORE Triple Driver BT In-Ears. There's a lot of stuff happening in the bass region of this song, and even though the 1MORE headphones can't tackle everything with surgical precision, they still do a good job of interpreting the haunting atmosphere of this piece. Also, Arnór Dan's voice never seems to lose its clarity and warmth. These headphones really do a great job with vocals.


Moving on to something much livelier and snappier, such as the Foo Fighters's "Learn to Fly", the 1MORE Triple Driver BT In-Ears really show off the energy and excitement of the sound they produce. Everything from Dave Grohl's vocals to Taylor Hawkins' masterful drumming sounds clean, powerful and effortlessly blended together. These headphones are very versatile in terms of music genres, with rock being one they excel at.


Massive Attack and Hope Sandoval (of Mazzy Star fame) recorded a song called "The Spoils", which will tell you a lot about how your headphones or speakers handle exceptionally deep bass, which plays practically throughout the entire song with various electronic and string instruments, and Hope Sandoval's mesmerizing voice as a layer on top of it all. Here's where the (sub)bass of the 1MORE Triple Driver BT In-Ears can get overwhelming, to the point where its boominess becomes annoying to the ear. When songs like this one come on, I tend to pull the ear pieces out slightly, which greatly reduces the boominess of the deepest bass. The same issue can be reproduced in pretty much any other song where the bass track digs exceptionally deep as it does here, such as the Ibeyi's "River" or Trentemøller's "Chameleon", which from the 0:32 mark onward becomes almost unbearable to listen to assuming you keep the ear pieces pushed in as deep as they'll go.

With that being said, I wouldn't consider getting the 1MORE Triple Driver BT In-Ears if I mostly listened to artists who dabble with excessive bass. At the same time, I can't say they aren't good for EDM as a whole because I listened to plenty of EDM music that sounded great on them (anything by deadmau5, for example). For other music genres, the Triple Driver BT In-Ears are either very good or downright excellent.
