Just like the charging case, the TWS1 Pro has a matte dark grey finish. The faceplates have an Edifier logo in the middle and are surrounded by a matching gold ring. There’s also an L and R marking on each one for the Left and Right sides respectively. A small LED flashes red and blue when the earbuds are in pairing mode.
Although it’s a simple design, it looks great, especially considering the sub $50 price. The shells are smooth all over, very lightweight and feel very durable. With an IP65 water resistance rating, the TWS1 Pro is perfectly suitable for working out or rainy days.
Internally, the earphones have Bluetooth 5.2 with Qualcomm® TrueWirelessTM Mirroring technology, meaning you can use either earbud left or right independently. In addition, the TWS1 Pro supports aptX Adaptive providing both lossless and low-latency audio.
The earbuds have touch controls for playback and call controls, including the holy grail of touch functions: volume control. Here’s a list of available operations:
Accept a call: single tap the left or right earbud
Decline/end a call: press and hold the left or right earbud
Pause/play: single tap the left or right earbud
Previous track: double tap the left earbud
Next track: double tap the right earbud
Volume up: press and hold the right earbud
Volume down: press and hold left earbud
When it comes to fit, the TWS1 Pro is one of the most comfortable TWS earphones I’ve tried. The fit is very secure even when I’m doing a demonic headshake, so these are ideal for workouts or playing sports. Passive noise isolation is pretty solid and similar to a wired IEM.
The charging case is matte grey in colour with gold Edifier branding on the top. A USB Type-C port for charging can be found on the back of the case and there’s a single LED on the front that indicates the battery life. It’s quite small (about the same size as the Sabbat E12 Ultra case) and with its rounded edges is very pocket-friendly.
The earbuds have an excellent battery life, with the buds lasting up to 12 hours on a single charge. With an additional 30 hours from the case, the total playback time is 42 hours which is really impressive for such an affordable model. The case has fast charging capabilities and can be topped up to full in just 40 minutes.
Qualcomm’s QCC3040 Bluetooth chipset provides Bluetooth 5.2 connectivity for lower power consumption and a more stable connection. The working distance is the standard 10m which I found to be accurate during testing. Pairing is fast and easy and the connection remained stable for me the whole time without any cutouts or disconnects.
The TWS1 Pro earbuds have cVc8.0 noise cancellation technology that integrates with the dual built-in microphones to provide better clarity. The mic pickup is sensitive and my voice plays back quite loudly. Voice quality is clear, although the mics do pick up some external noise.
Gear used for testing includes:
Sony NW ZX-300 (aptX)
The Edifier TWS1 Pro has a lively, dynamic signature with punchy bass and a forward treble. It’s a bit brighter than the average TWS earphone but is well balanced by a good quality bass.
I found myself really enjoying the bass on this earphone. It’s raised but not massive and has a strong mid-bass punch without any bloat. Decay speed is rather fast and leading edges are tight and snappy. It’s an engaging bass with good drive and a sense of rhythm.
Sub-bass notes are not as forward as the mid-bass but the TWS1 Pro produces a visceral rumble which is really engaging. The bass is a really vital part of the overall sound signature here as it’s required to counterbalance the forward treble. Not only does it do that but it does so with nimbleness.
The mids are vibrant and expressive thanks to a boost in the upper midrange band. Vocals and instruments have excellent clarity but can sound a little bright. However, the tone is generally pleasing and appealing, if not totally accurate.
Vocals show occasional hints of sibilance but for the most part, there’s no harshness or discomfort. This is an energetic, forward midrange with good articulation and prominent vocals.
In the highs, the focus is mostly on the lower treble. This gives the TWS1 Pro ample energy and clarity without becoming thin or brittle. You can hear lots of small details in the music: TWS1 Pro will reveal sounds that other TWS earphones bury under a blanket of warmth.
It’s a crisp, clean treble that doesn’t sparkle but is still quite airy and open. The effect of this treble tuning can be heard throughout the spectrum, from the clarity in the midrange to the definition and attack of percussion instruments.
The soundstage has fairly large dimensions and sounds good with large orchestral string sections. Positional cues are only average but still respectable for a budget IEM. Instrument separation is good and there’s minimal congestion even on busy tracks.
AUVI Studio-G ($59)
The Studio-G has a warmer tonality than the Edifier. It has thicker bass notes and comparable decay speed. Its warmth also carries through to the midrange, giving it a rounder, smoother sound. Detail retrieval is less than the TWS1 Pro but Studio-G has slightly better resolution.
The AUVI has a more laid back and smooth treble so would be more suitable for treble-sensitive people. In comparison, the Edifier is more energetic and vibrant and it has greater clarity. The Studio-G has a very low latency which is great for gaming and video while the TWS1 Pro has more than double the battery life.
The Edifier TWS1 Pro is a great all-around budget TWS earphone. Its build quality and battery life are excellent plus it has good call quality and a clear, vibrant sound. This is a no-brainer if you’re looking for a wireless earbud under $50.
