The tuning is not excessively V-shaped which was the case for CK3TW, nor was it too warm, which I found on the ANC300TW, nor was the bass too strong like the CKS50TW. Sony's connect app analyzes your unique ear shape, tailoring the audio to deliver the best possible 3D sound. These earbuds will be coming in a Japanese Black colourway with Dark Bronze accents, and you'll also get 12 different earbud sizes and styles to help you get both the perfect look and the perfect fit for any sensibility and ear.

Audio-Technica lets you calibrate the noise cancelling at the start of the setup and from there, you barely hear outside noises when the music is playing. Its design is unlike any that A-T has launched, the model number is also different, so they must have put in a lot of effort on the TWX9.I’m pleasantly surprised that a true wireless earphone could articulate a busy album like this so effectively. Compared to its rivals, the ATH-TWX9 has the sleekest-looking and most premium-feeling charging case. All said, Audio-Technica has come up with an attractive, top-notch pair of true wireless earphones in the ATH-TWX9.

Audio-Technica’s ATH-M40x wired headphones are ideal for professional studio tracking, mixing and monitoring. When subjected to constant music output peaking at 75dB (SPL), the earbuds lasted 5 hours, 24 minutes — not quite as advertised, but not necessarily bad. That said, I’d say the ATH-TWX9 may lack a little of the reach and extension that Sennheiser or Sony offer on their earphones, especially if you play a track, say, from the Tenet movie soundtrack that emphasises a lot of the low end. Started in June 2008 by technology journalists and ex-journalists in Singapore who share a common love for all things geeky and digital, the site now includes segments on personal computing, enterprise IT and Internet culture.Comparing wireless earbuds to Apple’s AirPods has become so commonplace that it’s kind of lost all meaning. Getting a good fit is essential to any headphone listening experience, and the people at Audio-Technica clearly know this because the ATH-TWX9 comes with no less than 12 sets of ear tips of varying sizes and lengths.
